There is a rule of thumb that one amp per one thousandths of thickness (up to around.125) will get you pretty close. Welding aluminum requires a thorough understanding of the tig welding process and also requires a tig torch. The metal produced in the weld pool is a combination of filler and parent metals that must have the strength, ductility, freedom from cracking, and the corrosion resistance required by the application.

Most of them hook up a switch on the torch and pulse weld manually by going from on to off again and again slightly overlapping puddles. Tungsten inert gas (tig) welding, also known as gas tungsten arc welding (gtaw), is best suited for welding aluminum and stainless steel. While mig and tig are commonly used methods for welding aluminum, there are several other types of welding that can be used:

On copper, from.032 to.090 the tig wins on cleanup if it can get penetration, otherwise the torch wins on penetration, and both are equal on distortion.

I’m gonna compare 50 hertz to 250 hertz. Gather the right electrode, rods, and shielding gas. This seems to break though the anodized coating.

I’m tig welding aluminum today, and i’m comparing ac frequency. I’m gonna set it up on a positioner and i’m gonna compare penetration, same amperage, 50 hertz, 250 hertz. I’m gonna compare 50 hertz to 250 hertz.

Start the argon gas flowing for a few seconds before striking the arc to ensure the weld area is fully covered. I prefer to tig whenever i can, but there are times when mig with a spool gun is the way to go. Some experts recommend backstepping the first inch or so of each aluminum weld before finishing in the normal direction.

Dc tig is generally used to weld exotic material like stainless steel, nickel alloys, copper, titanium and critical welds that must be flawless such as aircraft engine parts. Use a gas lens to distribute the shielding gas evenly and to create a smooth gas flow over the weld puddle. The plug is the same alloy, however it's solid, 1/8 thick 3/8 in length and it fits in the end of the tube.
