Video tutorial on welding methods and skills of aluminum alloy

A, aluminum welding methods and skills are as follows:

1, and the basic operation skills are solid. If it is the first time to use it, you should know the basic skills of gas welding, similar to argon arc welding.

2. An aluminum argon arc welding machine with good stability. This is a necessary condition for welding seam, and a good supplier needs professional guidance on the machine, because a good machine will be equipped with professional technical guidance.

3. High-purity argon needs the cooperation of local gas filling stations to provide high-quality argon.

4, high purity welding wire, welding wire with high impurity content will seriously affect the welding quality.

Second, pay attention to the problem:

1. Positioning is very important. When welding, try to keep the welding torch cable straight and minimize the wire feeding constraint on the soft aluminum wire. Bending of welding torch cable will lead to knotting of welding wire, which will lead to poor wire feeding.

2. The skill of correctly loading aluminum wire is very important for loading aluminum welding wire and avoiding welding failure. Hold the welding wire shaft safely with one hand to ensure that it will not loosen. After opening the cellophane package, hold the loosened end of the welding wire with the other hand, and don't let go before putting it into the driving roller.

3. To set the tightness of the welding wire brake, it is only necessary to ensure that the welding wire just now will not come loose, but it should not be too tight, otherwise it will drag the welding wire. To set it correctly, first adjust the tightness to the minimum, then install the welding wire and let it pass through the drive roller. If all the components except the welding wire roller stop, it means that it is not tight enough.
