Hello!
I'm new to the AWS and have only had about 6 months experience in using it at my current job. Something we have run into recently is an increase of weld sizes because of how high our parameters are now. I have found that for fillet welds under the GMAW/FCAW section (according to AWS D15.1 Clause 8; 8.5.2) the maximum size for a single pass for flat and vertical is 1/2", 3/8" for horizontal and 5/16" for overhead. However I can not find a maximum weld size for groove welds. Maybe I am misunderstanding 8.5.2.2 but I am trying to determine what the maximum size can be for each pass in a groove, whether that be the root, layers, or surface. I see it says other than root and surface welds they shall not exceed 1/4 inch, but what would the root and surface weld maximum be then?
Thank you!
