The last vessel,the customer accepted one SWPS, but it only went down to 1/16.I found only one other AWS procedure that was anywhere close,and it only covered 10-18 gauge sheet metal.
I told the customer that more that likely they will have to get one qualified thru a materials lab.The only other option I thought of was to see if they could use the WPS from the main contractor,and get qualified thru them.
Thanks for the response,Ringo
