Are there any Welder Qualifications or Certification per D1.1 for spot welding. I am not seeing anything in there and thought I would seek some veteran CWI's advice.

i think that is covered in aws d1.3 (sheet steel)

What materials are you spot welding? Resistance or arc? D1.1 only covers material thicknesses down to 1/8 inch, which you probably know. I'm appologizing for being so generic here, but I have seen references to spot welding when "plug welding" was the actual criteria as well. If D1.3 is the criteria, which it would be if the material is less than 1/8", then there should be procedures and qualified welders for this as per 2.3.5.1 & 4.6.4.1 (AWS D1.3-98). If this is resistance spot welding then I would like to see WPS's & PQR for review.

Jarsanb;

We are resistance welding sheet metal together and putting three and six projection spot weld nuts and studs on sheet metal also.We do not have any WPS's or PQR's for review written.

D1.3 cover up to 3/16" material

I believe I would recommend reviewing a resistance welding standard. To my recollection, the sheet metal code does not address resistance welding and the material would not be covered by D1.1 if it is less thn 1/8 inch thick.

Al;

Do you know where or whom I can retain this resistance welding standard from ?

It's in the catalog Mwccwi listed, pg. 30. If you do not have a WPS and have not tested certain combinations of equipment settings, then that is quite a bit to expect out of your operators. They just pull an arbitrary time/pressure/heat setting? Not to mention tip diameters for given gauges. You probably see an inconsistant product. These manuals do give alot of this information. If you don't have any I think it would be a must. The equipment manufacturer manuals are excellent as well. Now this has been a few years since I've been involved with resistance welding but I believe the best one I ever found was made by "Logan", but I can't find them on-line. Maybe that wasn't their name, hopefully some else can shed a little more light. Tuffalloy has some ok publications. Your distributor should be able get these if you don't already have them.

Go to the AWS website. I have a copy here somewhere, but it will take some doing to find it.
