Task 1: Test coupons

Time: 4 hours

Quantity: 3 specimens, either Single V-groove butt joint welds or

fillet welds.

Processes and Posistion


8/15

One test plate coupon for butt weld shall consist of two (2)

pieces, each 12mm in thickness,125mm width and 350mm inlength

The second test plate coupon for fillet weld shall consist of two

(2) pieces, 12mm x 100mm x 250mm and 12mm x 125mm x

250mm

The test coupon welded shall contain a stop / restart in thecentre 75mm of the cap pass.

GMAW (MAG), (135) only is to be used for the fill and cap passes

and the stop and restart shall take place only at the cap pass. A

weave or the last pass on a multi-pass welds considered for the

stop and restart.

GMAW (MAG) is also qualified to be used for a root pass and as

top and restart as above shall be applied for the root pass. FCAW

or MCAW (136) shall not be used for making root passes

The final test coupon shall be a pipe welding test consisting of

two (2) pieces of 168,3 mm Outside Diameter x 10,9mm wall

thickness (6Diameter SCH 80), 125mm length carbon steel pipe
