[MW:18977] Re: GMAW instead of GTAW +SMAW

Hi,

I need your technical advice on the use of SMAW qualified welders to participate on a GTAW procedure. Please note that initially we were using SMAW procedure but we decided to adopt an improved procedure, hence few welders were qualified on the GTAW.
My plan is to allow the welders on SMAW to fill and cap the root done by the GTAW welders.

Please advice me.
