MULTIMET® RTW™ Filler Metal
Product Description:
MULTIMET® RTW™ filler metal is used for the gas tungsten arc and gas metal arc welding of MULTIMET® alloy. The deposited weld metal has excellent strength at temperatures up to 1500°F and moderate strength up to 2000°F. The weld metal also has excellent oxidation resistance and good ductility. The RTW™ filler metal finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
