GFW310E

Applicable Specification

JIS Z3323 TS310-FC0
AWS A5.22 E310T0-1

Applications and Characteristics

TASETO GFW310E is used for welding AISI310 or SUS310S and welding dissimilar metals such as stainless steel and carbon steel combinations. Weld metal has excellent corrosion resistibility and heat resistance, because of the higher content of Cr and Ni than Type 308 weld metal.

Notes on Usage

Please refer to “Guideline for Welding Stainless Steel with GFW Wires”.
* Because of the fully austenitic structure of weld metal, the weld metal susceptibility to hot cracking is high. So, the welding current must be kept within 150～200A. In the case of highly restrained conditions, it must be kept within 150～170A. Keep the interpass temperature at 120℃ or below. To minimize crater cracks, fill craters with filler metal and remove crater cracks with a grinder.
Use 100%CO2 as shielding gas.

GFW625

Applicable Specification

AWS A5.34 TNi6625-04

Applications and Characteristics
TASETO GFW625 can be applied to welding of nickel alloy 625 (UNS N06625), welding of nickel alloy 800 (UNS N08800), welding on the clad side of nickel alloy 625 (UNS N06625) or nickel alloy 825 (UNS N08825) clad steel, and overlay welding of carbon steel. As GFW625 has a high PRE value and good resistivity for pitting corrosion, it can apply to welding of UNS S31254 class austenitic super stainless steel.
