What is Erratic in Welding?

Welding is generally classified as a process of joining two materials, usually metals or thermoplastics, by subjecting them to high temperatures. Welding takes advantage of the fact that many metals have a low melting point, and can be easily joined together using this method. However, sometimes the weld pool can be difficult to control, resulting in an erratic weld.

What can cause an erratic arc when MAGS welding?

Erratic welding can be caused by a number of factors, including:

poor Arcstarting Consistency,
incorrect torch angle,
or incorrect gas mixture.

This can result in the weld pool being difficult to control and can lead to imperfections in the final weld. In some cases, it may even be necessary to re-do the entire weld.

If you are experiencing erratic welding, it is important to first identify the cause of the problem. Once the cause has been identified, it will be much easier to correct the issue and avoid future problems.

A common cause of erratic welding is an incorrect gas mixture. The gas mixture is responsible for shielding the weld pool from oxygen and other contaminants. If the gas mixture is not correct, the weld pool can be exposed to oxygen, which can cause it to become unstable and difficult to control. Another common cause of erratic welding is an incorrect torch angle.

Good to know:

1) What is an unstable arc?

An unstable arc is characterized by an erratic, sputtering weld pool that is difficult to control. This can be caused by a number of factors, including incorrect gas mixture, incorrect torch angle, or poor Arcstarting Consistency.

2) What is sputter in welding?

Sputter is a type of welding defect that occurs when the weld pool becomes unstable and difficult to control.

3) Why is my welder skipping?

Skipping is a type of welding defect that occurs when the weld pool becomes unstable and difficult to control.
