Mig Welding Aluminum

While mig and tig are commonly used methods for welding aluminum there are several other types of welding that can be used.

Mig welding aluminum.

When mig welding aluminum the desired mode is spray transfer. Let s assume we are talking about 1 4 inch to half inch aluminum. The settings needed to mig weld aluminum are pretty much the same for all positions. Matt covers the basics of welding aluminum demonstrating techniques using a spool gun with a mig 175 welder from eastwood.

Mig welding thick aluminum with an underpowered welder. Beam welding techniques are commonly used for aluminum. Aluminum is a tricky metal to weld with a mig welder because it takes more heat than mild steel usually in the range of 21 to 24 volts. Electron beam welding has a very precise heat affected zone that can be easily controlled which.

This process is a very smooth transfer of molten metal droplets from the end of the electrode to the molten pool. Mig welding aluminum relies heavily on having the right equipment due to the soft nature of the welding electrode wire. Peter zila master aluminum welder is back to show klay some more aluminum welding this time with mig. For 1 8 thick aluminum unless you have the machine set just right the slow steady bead just builds up too much heat because by the time you reach the edge of the metal its really too hot and leaves a huge crater.

Here are some things to do that can help you when you are mig welding thick aluminum and your welder isn t quite up to it. Laser beam and electron beam welding. Listen up and take in the knowledge peter has to offer. Matt covers the basics of welding aluminum demonstrating techniques.

There are several aluminum mig welding techniques that work ok but the one used in the video is just a slow steady motion. Mig welding aluminum basics. Once the right equipment is set up it s a pretty easy metal to weld. In most cases it will take 21 23 volts to get the arc to spray transfer.

Pre heat the base metal with a hand torch before you weld. The droplets crossing the arc are smaller in diameter than the electrode. There is no short circuiting in spray transfer and the deposition rate and efficiency are. Pre heat your project piece.
