Dear Experts,

Our customer is forcing us to do multilayer welding for 6mm throat size, which is increasing our welding time because most of welding is in a6 size.

I have tried so many test coupon to prove that a6 can be done by single layer but I am not succeed in all test.

Customer requirement is root penetration at least 0.3 mm. But I am not able to achieve it. refer following parameters which I have used.

• Welding process :- GMAW
• Filler Wire :- ER 70 S6 (1.2 mm dia)
• Shielding gas :- 80 % Argon + 20 % Co2
• Current :- 245-255 Amp
• Voltage :- 26.5 to 27.5
• Travel speed :- 220 - 240 mm/min

Please advise any modification is required in the parameters.  

Should I change Shielding gas composition?

Waiting for your valuable reply?

Thank you

Vijay Katkar
