Stud Welding Overview

I like Miller Electric because of their people and their service. The best thing Miller has going for them is that when one of their welding machines breaks, They have great customer support.

Wages have gone down during the slow down. Not that long ago a “rig welder” (a welder with a Portable Welding Machine on a truck) in Alberta, Canada would average $330,000 a year, but times are hard, so it is roughly half that much now. Off-shore oil rigs employing 6G welders are paying about $100k a year right now.

Tig Welding Rod – 90 % of everything you will tig weld can be welded with 3 different tig rods. 308 for welding stainless, E70S2 – for welding mild steel and 4130, and 4043 for welding aluminum. There are all kinds of rods for specific applications but these 3 rods will handle most of the tig jobs you will do.

Now if you do decide to use a gasless MIG welding wire you are going to have to change the wire feed rolls. The reason for this is because it is a flux cored wire the wire is not solid all way through. So because the flux is on the inside of the wire the wire is very soft.

With the help of a gas welding torch, this rod gives the weld more tensile strength, elongation, low melting temperature and even the ability to get past impurities like corrosion, anti-freeze and oil. In the end, the welding area will actually become tougher than even the base metal.

The biggest thing going for the small machines is that they are now really cheap to buy. You can pick one up just about anywhere and they are much better and easier to use for welding jobs at home. They are light and small which makes them reasonable portable. You can pick them up and put them in the car to take around to a mate’s place quite easily. Try doing that with an industrial mig.

Next, measure 6″ from the free end and mark again. Bend the sheet at this point and this will be welded at the specific indication to the back of the overhang.

You are just about done now. Turn you gas back on. Now ideally you want the wire feed tension mechanism to be as light as possible so that it does not deform the shape of the welding wire. Deforming the shape of the welding wire will case premature wear on the feed rollers simply because of too much force. It will cause irregular wear on the contact tip and the welding wire will have tiny bits of material shaved and squeezed off it which will go down into the liner of the torch, and over time cause it to build up internal resistance which will cause more trouble welding down the track.
