I want to buy a welder and practice but might not be able to do this in my garage. So i was wondering is it possible to mig and tig out side in your drive way. or will this not work due to wind and outside temps or will this be ok.

 

It's fine, just don't weld in the rain lol

 

what kinda machine do u plan on getting? if you weld outside your better off with a flux machine and not using gas during the weld.

 

You might have problems outside using TIG or any other type of welding using gas.. Depending on how strong the wind is blowing it can disrupt the gas flow and contaminate your welds. I mean you could use something to block the wind and it shouldn't be an issue.

 

keep in mind if its bright outside and you light something on fire you might not be able to see it with the welding mask on. Other than that the other problem has been mentioned which is wind blowing your inert gas away from the arc. This is usually avoided with proper positioning though.

 

I plan on getting a miller mig and a miller tig and i wouldent do it in the rain or if it was really windy lol I would probually get a welding screen or 2 to block the wind and screen the arc from the neighbors and people driving by lol How would the temp affect this if it was cold or really cold out would this be a problem I'de love to do this in my garage but it's not that big and theres exposed wood all around and a rug in there so.

 

I have done a good deal of outside welding and my only issue was wind blowing the gas away, but I usually set up tarps for a makeshift booth or had one of my helpers hold up cardboard and I turned up the gas flow. And don't weld in the rain, it could be a shocking experience.

 

It'll be very shocking indeed. I was on a ship once welding some new plates in and it started raining and my coveralls were now wet then I leaned against the rail to strike my arc I got a nice zap. Couldn't feel my junk for hours, it was a scary experience.

 

flux core + outside = win.

 

Ok cool thanks for everyones input anymore more is always welcome. will the cold effect me welding.

 

IT would have to be extremely cold I would think for it to have a effect. I have welded steel stairs outside in 5 degree weather, though I was stick welding with 7011 rod. Never really mig/tig outside in really cold weather, usually that part of my job comes in the spring or is done in house. Others may have more insight though.

 

Yeah temperature doesn't make a difference for most steel, I used to work on ships in the middle of winter(it gets really cold up in the harbor, like -25C without the windchill). Only if you're welding iron or something of the like you'll have to preheat and keep the material at that temperature. Mild steel though, just have at 'er. Mig and tig will work, again you just need to shield your work area from the wind. The cold will start affecting you before it affects your work piece.

 

I've welded outside in about -5 degree weather, never had an issue .

 

temps involved in welding are hundreds or thousands of degrees so the 50*C change that you will get from a hot summer day to a cold winter one won't have a large effect.
It could come into play on larger work pieces where internal stress is introduced due to heating one side much more than the other, but to some degree this always happens on large pieces.
i would think this problem would be amplified in the winter though due to increased cooling rates, which can be a real problem with some materials
