well, at least in my thinking   |
Sully is talking about a bend test. No matter the type of weld if it is bent against the face and or the root without breaking or splitting in the slightest degree the weld passes. Whether it is a MIG weld or not.
Lets get this straight, many things that are used on a daily basis are MIG welded. For instance a Propane Cylinder ( which is a pressure vessel ), your car, and lets not forget the Airplane. Anything automated these days is MIG processed and in production as well.
There are ways around the cold start of a short circuit method of MIG operation.
