opperating temps for welding?

admin

out of curiousity, is there a certain temp range the work place needs to be for welding?  reason i ask is since it is becoming winter and i will be working in our unheated garage, will i be able to weld when it's only like 30 degrees if not colder outside?  i would assume so, but im a nub so i figure id ask hahaha,thanks.
Reply:Assumption correct, unless your garage is in Antarctica. Nice to be in a warm shop, though.
Reply:ok cool thanks lol.  i was reading some site where some guy said he didnt during the winter but that must have been more of a "aint tough enough" kind of thing lol.  cold never really bothers me cause you can wrap up, i just wanted to make sure the stell wouldnt like crack due to going from really cold to hella hot in a hurry.
Reply:unless your water cooler freezes up (tig only)lol but i weld all year ,its nice a warm when you do weld
Reply:the only "operating temp" is how hot and angry   you get sometimes when things don't go as planned..other than that there is no real operating temp......zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:perfect, thanks =).
Reply:Depending on the humidity at the time, you may want to preheat the joint to drive off condensation.  Some high strength/hardenable steels, such as a 1040 and higher carbon steels, may require some preheat and maybe postheat to slow down the cooling rate of the weld and help prevent formation of the brittle phase, martensite, in the heat affected zone.
Reply:Year round for sure.  I like the winter better because I don't have to run the kerosene heater in the garage once the steel starts getting hot.  You may even get a little more duty cycle if the welder can stay cooler due to the lower ambient temperature (probably can pickup a couple extra seconds before she overloads...lol).  This will be my first winter with the TIG unit and hopefully I will get to burn through a bunch of rods.A little pre-heat and post heat like Pulser say's is probably not a bad idea depending on where you live in the country.  My garage doesn't really get cold enough for that but you Northern boys probably need it.
Reply:Aws has a nice piece in it's code book which shows the ambient as long as it does not fall ie; 60 degrees farenhiet no pre heat is required to get rid of moisture or to stop hydrogen imbrittlement. If it does fall below the sugested ambient temperature a good rule of thumb is a 200 degree preheat aws again has a pre heat info based on base metal thickness. The thicker the material the greater the pre-heat also remember when pre-heating to heat a larger area then you intend to weld so you don't loose the heat right away.
