Aluminum welding is one of the most difficult welding processes. The metal itself is refractory. After all, there is an oxide film on the surface of aluminum. This is why aluminum is welded on alternating current (AC/DC). Only some argon arc devices support this type of welding. Separately, you need to have the skills of argon arc welding.
Despite this, it is possible to master argon arc welding of aluminum at home.
The video was created to show the entire process of welding aluminum with an argon arc device on alternating current. From choosing the device to obtaining a high-quality welding seam!
After this video, you will learn the basics of aluminum welding (using an argon arc machine on alternating current) and get the basic skills for work!
The video is intended for beginning welders and professionals. In the video, we will consider the following topics:
- What is aluminum welding, what are the general principles of welding and why is it so important to work with this metal;
- Why welding takes place on alternating current;
- What argon arc device is needed for aluminum welding;
- Setting up the argon arc device for aluminum welding;
- Selection of welding torch, selection of gas lens and nozzle;
- Selection of tungsten electrode and welding rod;
- How to sharpen a tungsten electrode;
- Correct setting of gas pressure for welding;
- How to prepare aluminum for welding;
- We will tell general recommendations for argon arc welding of aluminum;
- We will show the welding process in practice;
