Re: [MW:11542] GMAW application restriction

dear,


GMAW process with  proper combination of shielding gas with some advance features power source can be used for root welding. This process is widely used in cross country pipeline welding.this process is used in pipeline welding is to increase the production rate.

 
Why GMAW is not widely used for single sided full penetration joints (with out chip back) for pressure vessel industrial applications?
Is there any problem regarding to penetraiton or lack of fusion? I am confusing. Request you to give technical answer.
