I was wondering what the criteria were for a good mig weld. I know that arc is 2x diameter and no more than 1/8 high, but i'm not sure for mig. Any help would be nice. thanks
Reply:It depends on the connection design. The engineer will give every parameter in print. Or is this just hobby-work or practice? Just make them uniform. Consistant, consistant, consistant. You want a nice even heat signature.City of L.A. Structural; Manual & Semi-Automatic;"Surely there is a mine for silver, and a place where gold is refined.

Reply:criteria would be the same. when going from stick to mig the code does not give you the freedom to have more undercut, porosity, etc.only thing worse than an ugly woman is an ugly weld
Reply:Mark,If you're talking stickout, there really are too many variables to give a definitive answer.Depends on a multitude of factors such as: wire size, solid vs flux core, voltage/amps, short arc or spray, etc. etc etc.You may wish to download Miller's Guide to GMAW which is available on their website. It goes into great detail about how stickout affects the weld bead.
