Re: [MW:28140] Weld bead length

Dear Steve,

Thanks for your suggestion, but my client asking us to start multi run welding after hot pass, actually we are doing multi run for cover pass. As it is very difficult to weld multi run in narrow groove.

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,
