TIG Welder Interview Questions and Answers

Cracking in welding can occur due to various reasons such as improper welding technique, high stress, and material defects.

• Improper welding technique such as using too much heat or not using enough filler material

• High stress on the welded joint due to external forces or thermal expansion/contraction

• Material defects such as impurities or inclusions in the base metal

• Inadequate preheating or post-weld heat treatment

• Incompatible welding materials or dissimilar metals

• Lack of prope...read more

No, in TIG welding, argon gas is essential for shielding the weld area.

• Argon gas is commonly used in TIG welding to create an inert atmosphere around the weld area.

• The inert atmosphere prevents oxidation and contamination of the weld, resulting in high-quality welds.

• Using a small gas or any other gas instead of argon can lead to poor weld quality and potential defects.

• Examples of other gases that cannot be used in TIG welding include helium, nitrogen, and carbon dioxide.

The brake system is allowed to ensure safety and control in vehicles.

• The brake system allows vehicles to slow down or stop, preventing accidents and collisions.

• It provides control and stability to the vehicle, especially during turns or on slippery surfaces.

• The brake system also allows for smooth and gradual deceleration, enhancing passenger comfort.

• Emergency braking systems are crucial for sudden stops or avoiding obstacles.

• Different types of vehicles may have specific brake...read more
