Top 10 Questions for Metal Fabricating Supervisor Interview

1. Can you explain the process of aluminum welding?

In aluminum welding, the process involves joining aluminum pieces together using heat and a suitable filler metal. The steps are as follows:

• Preparation: The aluminum surfaces are cleaned to remove any impurities or oxides that may hinder the welding process.
• Gas Selection: A shielding gas such as argon or helium is used to protect the weld area from atmospheric contamination.
