Re: [MW:28139] Weld bead length

All,

Your client is right, multi bead welding  for cover pass - with SMAW - ensures fine grain weld metal and eliminates the risk of undercut which is the result of high amperage and incorrect electrode control.

Dear Gentlemen,

We are doing welding of LTCS materials, while welding some of the

joints we welded final run in single bead which is as per approved

WPS(3 x electrode dia.)  Our client is asking us to do multi bead

welding above 6" pipe even though the gap in groove is below 9 mm. We

are using 3.15 electrode to do the final run. We are maintaining heat

in put in control. Please clarify me whether it is correct or not?

Thanks & Regards

N.Kiran kumar,
