Best Procedure Weld Technique to build-up Pipe
Best Procedure Weld Technique to build-up Pipe
(OP)
Hi All,
I was wondering what welding techniques are optimal for building up thinned piping without burning through. In other words, what techniques allow you to lay down good filler with very minimal penetration? I'm looking for information not just on process (GMAW,GTAW,SMAW) but also on other factors affecting penetration like travel speed, etc.
I have read that with stick welding with 6010 electrodes, slow travel speeds actually tend to lead to less penetration which is opposite of what I would have suspected.
Thanks,
bob

You have quite a bit of manipulation with the manual GTAW process because of the local heat input that works in your favor. GMAW could also be used for welding on thinned material, but you have to be experienced with GMAW to avoid lack of fusion type weld defects.

The above should be "arc blowing" not bowing
