crij Posted October 28, 2009 Share Posted October 28, 2009 (edited) On this topic, you will get many opinions. Personally I prefer TIG when welding overlapping patches and butt weld patches with minimal gaps, but if there are many finger sized gaps (i.e. when repairing hand cut Oxygen/Acetylene holes) I prefer flux core MIG. As I don't do this for a business, I rarely have to worry about welding in the wind or foul weather, and a TIG with a gas lens has worked good for me even in a mild breeze and in the summer with a fan. To me one of the best advantages of TIG over MIG is that you can use less heat to weld the same metal, while not ideal for most situations it works when needed. Then there is also the fact that TIG produces almost no sparks and no splatter when working correctly. Rich C.

arftist Posted October 28, 2009 Share Posted October 28, 2009 Patch panels on what? For a ship, I would use a different method than for a toyota fender. Assuming you are talking about autobody, either would work, but bodyshops use mig for the most part. Quote Link to comment Share on other sites More sharing options...
pinetar Posted October 29, 2009 Share Posted October 29, 2009 No tig exp. here, but I really like my Oxiweld mig on steel and alum. New in 1968. Quote Link to comment Share on other sites More sharing options...
Minionsram Posted November 5, 2009 Share Posted November 5, 2009 A mig is what is mainly used in auto body. I have used mig and tig. I normally grab the mig because it is quick and simple. Quote Link to comment Share on other sites More sharing options...

JeremyP Posted November 8, 2009 Share Posted November 8, 2009 I usually use mig, its faster and simpler and less likely to distort the metal if you are doing larger patches Quote Link to comment Share on other sites More sharing options...
jonathan king Posted December 16, 2009 Share Posted December 16, 2009 Tig is very good if you are looking for a clean weld with clean metal and little distortion. but its an expensive process to do eg the consumables. It is a longer process to learn and master. Mig welding is a faster process and some would say a semi skilled process but for genral welding it is great for joining steel ali and stainless. But both have their merits and pitfalls. all the best john Quote Link to comment Share on other sites More sharing options...
