Description and Applications |
|
HM347 is a gas
metal arc welding wire to be used with Ar+0.5%～2.0% O2
shield gas. Deposited metal contain Nb. It shows
excellent resistance to inter-crystalline corrosion and
high temperatures. Welding of SO5347, 321, 304L
stainless steels. |

|
Guideline in Usage |
|
When high
X-ray quality is required, stable spray transfer
mode should be maintained with low current and
slow welding speed using a pulsed arc and power
source. |
