MIG welding process-reg

[Karthikeyan Shanmugananthan]

Dear Experts
Can we use MIG welding process for load carrying structural steel.... and also provide limitations of MIG welding process

Expecting your valuable suggestions

Yes you can, but not outside because the gas shield gets blown away. The big issue is lack of fusion defects. I hope that you have trained welders, qualified welding procedures and non-destructive testing, and that you are working to a recognised welding code of practice.

The limitations of MIG welding has a lot of Depends:
1. Depends on Base Material.
2. Depends on Welding Wire
3. Depends on Shielding Gas
4. Depends on Welding Mode and Transfer
5. Depends on Heat Inputs
6. Depends on Joint Design

Mode of metal transfer plays a major role to choose this conventional GMAW process. If u have pulsed GMAW, in all current it will be in the pulsed spray mode only and u can use it for any thick, any position?

No issue .
Qualify PQR and use .
Use latest power source /wire feeder from reputed  welding equp manufactures

[Kannayeram Gnanapandithan]

if it is conventional power source, restrict to below 13mm or go for FCAW
