[MW:28985] RE: 28982] Backing gas as per API RP 582

Manoj,

 

SMAW never requires back purging. It's the "slag" generated by the process, which protects the weld root. This is just back to basic scenario.

Thanks.

Dear Experts,

 

As per clause 7.3 of API RP 582 Ed. 2016 back purging required for GTAW & GMAW process but no where I could found for other process like SMAW.  Is it mean that if we do welding with SMAW process back purging is not required?

 

Please share your interpretation.

 

Thanks and regards

 

Manoj.
