Re: [MW:25959] Fillet size a6 with single layer (GMAW welding process)

     Mr. Vijay

      

      As pointed out by you,  a 6, throat can be welded using single pass technique.

     The leg length  will work out to be 8.50 mm or 9.00 mm  . You easily get it using

     following parameters. 

     Have carried out hundreds of joints in 2F position.It can be achieved with few

     trails at your end and without any undercuts.

     You can also succeed with 

• Welding process :- GMAW.
• Filler Wire :- ER 70 S6 (1.2 mm dia)
• Shielding gas :- 80 % Argon + 20 % CO2
• Wire feed 10.30  m/min. on Lincoln  or 9.90 m/min on Miller or it may vary                 depending up on machine and its condition.
• Current : 280 - 290  Amps
• Voltage : 28.5 to 29.
• Travel speed : 270 - 300 mm/min
• Position 2F

    If you need any further info. pl. let us know.

Use 1.6mm, amp around 355

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
