Over the weekend I bought a welder (Lincoln 140 MIG), helmet, gloves, ans a few sheets of 16 gauge mild steel for practice; and next week I am going to go buy a tank of sheilding gas.
I also bought a book on welding, and it said that welding should be done in a shop where the ambient temps were 90 degres. The author said that 70-80 was ok, but you should not weld when the temperature is cooler then that due to the increased risk of cracking whatever metal you are welding. My initial thought were "Well, there goes my plans for the next couple of weeks," as my garage is unheated and has been between 25-50 degrees for the past months, and will stay there through March. I'd rather not wait till summer to learn how to weld, but I don't want to crack the body of my car - or the longs for that matter. I'd never heard the temperature thing before. Is it considered safe to weld when it is chilly out, or do I need to wait for warmer days? Zach |

Twisted, what kind of pipe work do you do?
I think B31.1 or B31.3 requires preheating under certain temps (like 60F?). That may be only for stainless applications tho. Not sure, we have heat and AC in our shop. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |
