Punj Lloyd Interview Questions, Process, and Tips

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

• Incomp...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 ...read more

Water cement ratio in concrete is the ratio of the weight of water to the weight of cement used in the mixture.

• Water cement ratio is an important factor in determining the strength and durability of concrete.

• A lower water cement ratio generally results in higher strength concrete.

• If the cube strength differs by 12%, it indicates a significant variation in the concrete mix.

• To address this, the water cement ratio can be ...read more
