Description and Applications |
HM316 is a gas
metal arc welding wire to be used with Ar+0.5∼2% O2
shield gas. Arc is stable, and has a beautiful beaded
appearance. Its ability to weld is satisfactory. Its
metal deposits contain an adequate amount of ferrite and
shows excellent resistance to heat cracking.
Welding of 18% Cr- 12% Ni- 2% Mo steels for chemical
engineering and power plants. |

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. |
