Welding - Strength as related to process
Ugggh
Gas Metal Arc Welding (GMAW) or commonly MIG welding and Gas Tungsten Arc Welding (GTAW) or commonly TIG are indeed two welding processes.
If someone could explain how one method produces a stronger weld than the other, assuming correct application of each method, I'd appreciate it.
Good luck

I agree with serene, unless you are welding al, chmo, or ss, it is pretty much a waste of time.
TIG is a process that can take as long as you want it to. There is no splatter, and you have complete view of the molten weld pool. The length of time of the heat up and cool down of the of the metal being welded is beneficical because this is essentially the heat treatment of the metal. Other than that is is the clearer view of the pool of molten metal that gives a very experienced tig welder the advantage over the the mig process(for mild steel). Preperation of the weld area can have an equal affect in each case.
Like i said before MIG is better than TIG in the hands of an experienced welder.
I have TIG'd AL and it came out looking good the very first attempt, granted i was experienced with other techniques. I have no doubt that an experienced welder could do better. 99% of my experience is with steel, and given the fact that a good weld will not fail at the weld, i don't see the significance of TIG except for exoticn material components, or unless the its the thoretically preferred process for educational purposes. No offense to anyone who thinks TIG is leaps and bounds ahead.

Welding on cast iron is a good example of where a tig can come in handy, instead of using the IMO akward stick welder.
TIG welding is used for exotic metals and thin stuff, thats basically all its really used for. However if you feel the need, anything that can be welded, can be welded with TIG, so have at it!
