WELDING IS A KEY MANUFACTURING TECHNOLOGY !
It contains MATERIAL SCIENCE and MECHANICAL ENGINEERING
and AUTOMATION AND ROBOTIC
ADVANCED MANUFACTURING 06.06.2012
MATERIAL SCIENCE BASED WELDING RELATED PRODUCTS AND THEIR R&D ACTIVITIES
EXAMPLES OF R&D ACTIVITIES… POWDER (Flux) WIRES ELECTRODES
06.06.2012
CASE 1: SUBMERGED ARC WELDING (SAW) PROCEDURE
• SAW – Submerged arc welding process u s e s W IRE and POWDER ( F l u x ) combinaLon.
• The metal is joined by fusing with an electric arc between wire and the metal. Powder (flux) spread in a deep layer over the weld area. • Powder shields the arc and molten metal.

POWDER CONTAINS VARIOUS ELEMENTS AND NEEDS FOR R&D FOR OPTIMUM COMBINATION!!
FOR GOOD WELD, WE NEED QUALITY POWDER (FLUX)!!
In November 2011, GeKa Flux branded SAW flux has been put on the Turkish market with a capacity of 5000 tons/year.

We have number of wire alternaLves for different type of materials.
UNIVERSITY-‐INDUSTRY COORPERATION
R&D PROJECTS
1. Developing NaLonal Flux Cored Wire Welding Technologies
2. Developing Welding Process and Filler Metals for High Strength Pipeline Steels
3. Developing Low Temperature TransformaLon (LTT) Weld Filler Consumables for Manual Metal Arc and FCAW Processes
EXAMPLES:
06.06.2012
Developing Na_onal Flux Cored Wire
Welding Technologies
Aim: Developing flux formulaLon and manufacturing flux cored wires
Mo_va_on: Easy handling, suitability for otomaLzaLon, higher producLvity and significant lower risk of defects such as porosity and lack of fusion
Dura_on: 16.03.2009 -‐ 31.12.2011 Budget : 1.900.000 USD
06.06.2012
Developing Welding Process and
Filler Metals for High Strength Pipeline Steels
Aim: Developing submerged arc welding, gas metal arc welding and manual metal arc welding processes and developing consumables for high strength pipeline steels.
Mo_va_on: ReducLon in pipe wall thickness, lower consumable consumpLon, shorter weld Lme and lower pipe transportaLon cost lead to reducLon in overall cost of the construcLon, operaLng pipelines with higher pressure resulLng an increase in gas transportaLon efficiency.
Date: 01.09.2010 -‐ 01.09.2013 Budget : 680.000 USD
06.06.2012
Developing Na_onal Low Temperature Transforma_on Weld Filler Consumables for
Manual Metal Arc and FCAW Processes Aim: Developing low temperature transformaLon weld filler
consumables Mo_va_on: Lowering amount of distorLon and tensile residual
stresses. High faLgue strength and faLgue life for high strength steel structures.
Date: 01.01.2011 -‐ 31.12.2012 Budget: 870.000 USD
