Instructions of Using Stick Electrodes

Storing Stick Electrode

1. Electrodes in unopened package retain the proper moisture content when stored in good

condition.

2. Once the package is opened, electrodes should be stored in a cabinet at 120°-150°C.

3. Dry the electrodes at 300-350 for 60 minutes, and keep at 100-150 before welding. If

exposed to humid air for excessive time, electrodes may pick up enough moisture to affect

operating characteristics or weld quality.

4. Over-drying could damage the electrodes. Please -dry condition for stick electrode

(page )

Welding Procedure

1. Please check welder before welding. Insulate yourself from work and ground.

2. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the

breathing zone.

3. Clean up the contaminations on the work piece to prevent welding defects.

4. Arc strike or re-strike of low hydrogen electrodes should be performed with back-step method

(refer to page 1-8).

5. Choose proper welding current to prevent large spatters or poor weld quality and

mechanical properties.

6. Keep proper width of weaving to prevent slag inclusion and undercut.

7. Apply proper preheat and Interpass temperature to prevent cracks in welds and HAZ when

low hydrogen electrodes are used to welding mid/thick plates.

8. Low hydrogen electrodes should be applied to the base metal with higher carbon, phosphor

or sulfur content.

9. The X-ray quality welds is improved if the joints are ground before the root pass welding.

Instructions of Gas Metal Arc WeldingWelding Instruction

(1) Use a CO2 shielding gas corresponding to ANSI/AWS A5.32/A5.32M SG-C or an equivalent CO2 gas purified for welding.

(2) Control the mixing ratio of Ar and CO2 in an Ar-CO2 admixture shielding gas because fluctuation of the mixing ratio affects the usability of a solid wire.

(3) Adjust the shielding gas flow rate in the 20 to 25 l/min range.

(4) Use a wind screen in welding in a windy area because a strong wind causes blowholes.

(5) Use a proper ventilation system at where general ventilation is inadequate.

(6) Keep the tip-to-work distance at around 15 mm with welding currents less than 250A and at around 20 to 25 mm with welding currents over 250A.

(7) Store welding consumables in a warehouse where the humidity is low.

(8) Use downward welding in the inclined position or forward welding on thin sheet. (Refer following figure)

(9) Impropriate transportation way causes clamp of wire and spool deformation during transporting plastic spool and basket spool.

Appendix B

Instructions of Gas Metal Arc WeldingWelding condition

Please choose appropriate welding condition during GMA welding because different welding conditions cause different bead appearance and penetration.

a. Torch angle

( 1 ) Narrow and convex bead

( 2 ) Deep penetration

( 3 ) Prone to blowhole

b. Fast travel speed

( 1 ) Narrow and convex bead

( 2 ) Shallow penetration

( 3 ) More spatter

c. Long tip-to-work distance

( 1 ) Low current at constant wire feed rate

( 2 ) Prone to curvy bead

d. Surface contamination e. Shielding Gas

Surface contaminations (oil, plant,

coating, plating and rust) cause the

formation of blowhole

( 1 ) Less flow or wind cause the formation of

blowhole

( 2 ) Different shielding gas affects arc, bead

appearance and weld properties

f. Nozzle position g. Too high current h. Too long arc length

( 1 ) Too high nozzle position cause insufficientprevention of gas to form blowhole

( 2 ) Too low nozzle position causes spatter to attach in nozzle

( 1 ) Wide bead width

( 2 ) Deep penetration

( 3 ) Convex bead

( 4 ) Small spatter

( 5 ) Poor bead appearance

( 1 ) Wide bead width

( 2 ) Flat bead

( 3 ) Shallow penetration

( 4 ) Large spatter

Appendix B

Drum packageArrow Pack is a pail-pack of large amounts of flux-cored wires and solid wires for gas shielded arc welding, in which the wire is spooled into the drum from its bottom to the top in coil by a unique way. The wire is spooled to be elastically twisted in the pail so that the wire can be pulled out straight without rotation of the pail. The wire makes good tracking on a welding seam. The use of Arrow Pack wires can reduce the downtime for changing wires when compared with conventional spooled wires, which is effective particularly for robotic welding and other automatic welding.

Instructions of Gas Tungsten Arc WeldingFeatures

Advantages of gas tungsten arc welding are less spatter, stable arc and excellent bead appearance. Tips for better welding results in Gas Tungsten Arc Welding

(1) Use the DC-EN connection with the constant current or drooping characteristic DC power source in general applications.

(2) Use an argon gas with a high purity to prevent pits and blowholes in the weld metal and decrease consumption of tungsten electrode. Adjust the shielding gas flow rate in the 12-18 l/min range.

(3) In order to keep the shielding of molten weld pool in good condition, the extension of a tungsten electrode from shielding nozzle should be approx. 5 mm. Maintain the arc length at 2-3 mm. The use of an excessively long arc length can deteriorate the shielding effect

and causes undercut.

(4)Because the quality of gas tungsten arc welds is markedly affected by dirt on groove

surfaces, scale, rust, water and oil must be removed before welding because they cancause pits, blowholes and unstable arcs.

(5) Use a wind screen in a windy site to maintain the shielding gas in good condition. Use an appropriate ventilation system where welding is carried out in a confined area to prevent welders from oxygen deficiency.

Instructions of Flux-Cored Arc WeldingFeature

Flux-cored wires offer excellent weldability with good arc stability, bead appearance, slag

removability and low spatter generation. High deposition rates and welding efficiency of wires are due to high current density, as shown in figure 1.

Welding Instruction

(1) Store wires in a warehouse where the humidity is low.

(2) Because the wire is softer than solid wire, do not excessively tighten the pressure roller of the wire feeder so as not to cause the deformation of the wire.

(3) In flat butt welding, backhand technique is better for stable penetration. In horizontal and overhead fillet welding, forehand technique is better for flat bead appearance.

(4) In vertical down fillet welding, the first layer run should be straight and keep the welding speed faster to avoid slag inclusions and to get better penetration. For the 2nd and subsequent layers, remove the slag of preceding beads and avoid weaving, refer for figure 2.

(5) Use a proper ventilation system at where general ventilation is inadequate.

(6) In one-side welding, welding parameter should carefully be selected to prevent welding defects such as hot cracking.

(7) Use a wind screen when wind velocity is more than 2 m/sec for gas shielding and 10 m/sec for self-shielding, respectively.

(8) Use a CO2 shielding gas corresponding to ANSI/AWS A5.32/A5.32M SG-C or an equivalent CO2 gas purified for welding.

(9) Other instructions refer to P2.16 and P2.17.

Instructions of Submerged Arc WeldingFeature

Submerged Arc Welding is the combination of flux and wire. Wires include solid wires and flux cored wires. Flux is classified as fused and agglomerated flux.

Welding instruction

Accuracy of groove sizes:

The accuracy of root gap and groove angle affects the quality of welds much more than with other welding processes; where the accuracy is poor, burn-through, lack of penetration, excessive or insufficient reinforcement can occur.

Surface of groove:

Rust and oil in the groove must be removed before welding to prevent pits and blowholes.

Storage and dry:

Store flux in a warehouse where the humidity is low. Before use agglomerated flux, the flux must be dried at 200~300 x 1hr and fused flux must be dried at 150~350 x 1hr.

Distribution and circulation of flux:

Where a flux is supplied excessively on the base plate, the bead appearance becomes irregular particularly in use of melted fluxes. In case where a flux is used repetitively by means of a circulation system, the flux can be contaminated with scale and dust and its grain size distribution can be varied; therefore, add new flux occasionally to maintain good performances of the flux.

Grain size of flux:

Sever grain sizes are available for a certain melted flux. The most proper size depends on welding currents to be used. The use of high currents with a coarse grain size flux can deteriorates bead appearance; in contrast, the use of low currents with a fine grain size flux can cause pock marks because of poor degassing.

Welding condition and penetration:

Submerged arc welding can use a wide range of parameters such as wire diameter, welding current, arc voltage and welding speed; however, erroneous setting of theparameter causes burn-through, and insufficient or excessive penetration and reinforcement. The bead shape can be affected by the travel angle of a wire; that is, where the wire is leaned to the direction of welding (backhand welding), the bead shape becomes narrower with comparatively deep penetration. In contrast, where the wire is leaned to the opposite direction of welding (forehand welding), the bead shape becomes wider with shallower penetration.

Submerged arc flux and wire for High Tensile Strength Steel

Submerged arc flux

Kuang Tai manufactures three types of submerged arc fluxes:

(1) acidic flux: KF-330, (2) neutral flux: KF-550,(3) basic flux:KF-990.

KF-330 It has excellent performance characteristics, including very good slag removal, making it

the most common choice for a variety of applications. The faster freezing of KF-330 slag

minimizes spilling on roundabouts. It is designed for welding on rusty or scaly sheet steel

and single arc high speed welding.

KF-550 General purpose flux designed to weld butt joints and both single and multiple pass fillets.

It can be used for automatic and semi-automatic welding. It provides good impact

strength and slag removal

KF-990 It has good operating characteristics and produces excellent impact properties when use

KW series wires and is the ideal flux for most double ending applications.

Instructions of Welding Stainless SteelFeature of stainless steel

The corrosion resistance of these steels, which is based on the passivating effect of chromium due to the formation of dense, adhesive, thin passive films, is brought about by Cr contents above 12 %.Stainless steels are also classified by their microstructure:austenitic, ferritic, martensitic, precipitation-hardening martensitic and duplex stainless steel. The common austenitic stainless steels, such as Type 304, have lower thermal conductivity than carbon steels and this is useful in applications such as cappuccino cups and thermos flakes. Their rate of thermal expansion is also greater than ordinary steel.

Welding instruction for stainless steel1. Arc length:

Nitrogen and oxygen enter into weld metal and reduce ferrite content when arc length is too high. Therefore, keep the arc as short as possible.

2. Welding current:Use proper welding currents because the use of an excessive current causes

overheating of the electrodes and thereby welding usability and weld metal mechanical properties can be deteriorated.

3. Groove cleaning:Cleaning should be done just prior to welding to prevent the formation of oxides.

The groove surface must be free of grease, oil, paint, dirt, etc. A clean surface will provide a smoother, stronger joint. Brush the plate surface & edges with a stainless steel wire brush to remove burrs & oxides. Gloves should be worn to prevent hand oil or dirt from getting on the joining surface.

4. Distortion control:Distortion of stainless steel is very large after welding process. Several

techniques can be used to reduce weld distortion, such as controlling heat input, using clamp and changing welding process.

5. Crack prevention:Welding austenitic stainless steel with low ferrite content is easy to produce the

crack at high temperature. It is noted that arc crater should be filled to avoid crater crack before extinguishing welding.

6. Heat treatment:The preheating, interpass temperature control and post welding heat treatment

are not necessary when welding austenitic stainless steel. Use higher travel speedto avoid the effect of excessive heat input and carbide precipitation. However, the preheating, interpass temperature control and post welding heat treatment are necessary when welding ferritic stainless steel.Take extra caution when performing the heat treatment to avoid carbide precipitation included cracking and distortion.

Stick Electrode for Cast Iron

Instructions of Welding Cast Iron

1. When cast irons have impregnated oil, the base metal must be heated at 400°C to

burn off the oil before welding. Other contaminants should also be removed off

before welding.

2. Stringer welding with the maximum bead length of about 50 mm is recommended to

prevent overheat, distortion and cracking.

3. Peening is needed to minimize residual stresses. Just after one bead was laid, it

must be peened with a hammer to the extent that the ripple of the bead disappears.

4. To repair a defect, it must be removed completely by machining or grinding (arc air

gouging is not suitable for cast irons) before welding. The welding groove should

have a round bottom for better fusion. Where a crack defect seems to be

propagated by machining or grinding, make stop-holes at both ends of the crack.

5. Ni-based cast iron electrode is good for welding in working piece that is no preheat

requirement or small area welding.

Stick Electrode for Arc Cutting

Instruction

Air carbon-arc cutting (ACC) is a process of cutting, piercing, or gouging metal by heating it to

a molten state and then using compressed air to blow away the molten The equipment consists of

a special holder, that uses carbon or graphite electrodes and compressed air fed through jets built

into the electrode holder. A push button or a hand valve on the electrode holder controls the air jet.

Welding Instruction

1. Extend the carbon electrode less than 6"(150mm) beyond the holder to prevent heat buildup

decreasing. While using, the recommended the length of carbon electrode is 3"(75mm) as carbon

or graphite electrodes become smaller.

2. Generally, the electrode is operated with the electrode positive and the metal is melted and

removed quickly.

3. The glass of mask is No.12~14 perfectly.

Welding Backing Material

Ceramic Backing Tape

--------------------------------------------

Introduction

1. Designed for general welding, weld backing tape produces smooth and homogeneous bead

by supporting the puddle and forming back beads during plane welding.

2. Weld backing tape speeds production, improves worker efficiency and reduces costs.

3. It allows one-side welding for steel, alloys and aluminum of any thickness. The product is

composed of ceramic tiles attached to aluminum tape on which specific heat-resistant

adhesives are spread, shown in following figure.

Welding instruction

1. The crack occurs in the first pass weld as use high current/ speed welding.

2. Shrinkage hole and crack occurs as stop welding. They should be removed with for post-weld

grinding and cleaning before re-welding .

Base Metal

The backing tape would be ideally used for welding in mild, alloy steel, stainless steel and

non-ferrous metal

Applications

It is suitable for one-sided welding of deck, strake, shell plate, bridge and box-beam, such as

shipbuilding, boiler/vessel storage tank, fabrication and non-ferrous metal industries
