I have welded in subzero weather inside, outside, upside down, right side up, with out any preheat on several continents with no known issues.........But.........as a self taught welder, no one ever told me it needed to be preheated.   Well, Neal, if you think about it it does have merit! Gosh I hope I don't have a trail of broken items backtracking me all over! Oops!!

I'm sure with good penetration and a proper bead your welds should be just fine in any weather we encounter here in the lower 48 states, or is it 57?    Ya that's right we have 48 they have 57, well never mind!    I would inspect the welds a little closer for cracks after cooled and you clean them up.

Subject: cold weather welding

hi all, i hear tell that preheating lets welds sink in easier, and

supposedly  is less stressful on the metal when its cold. so my  new

shop is unheated,and heating it is not a possibility, financially or

physically. It gets somewhat cold here in Oregon in the winter, not

like Wisconsin cold, but cold enough that the metal wouldn't like it.

lets say i want to weld in some sub-frame connectors. my idea is cut

them perfect and set them on the wood stove to warm , and heat the

underside of the car with a couple halogens. would that do it or do i

need to go much hotter to do any good, , as in an oxyacetylene setup.

or how about heating the underside with a torpedo heater. would that

do it? i don't have an oxy setup and cant afford one.
