JIS Y347
AWS ER347

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.
