Description and Applications |
HM310 is a gas
metal arc welding wire to be used with Ar+0.5～2%O2
shield gas. Deposited metal contains a full austenitic
structure with excellent corrosion, acid, and heat
resistibility.
Welding of 25% Cr-20% Ni stainless steel, dissimilar
metals such as 18% Cr-8%Ni stainless steel to carbon
steels for petroleum and chemical industries. |

|
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. |
