Hi guys I'm gonna be relocating to a new town and am gonna be getting a new job. I can pass a welding test as far as welding goes, but they also have a written test. I've never taken a written test, and I dont know all of the technical stuff. I can weld, but I just don't know the insides and outs as far as temps and things go. I mean If I can tell when to turn it up or down on different metals, just don't know the different temps for different metals and so forth. Also about different gauge wire for different thickness of metals. Does anyone know of an online test that explains all of the Qs and As ? I've done a google search but no luck. thanks.
