Genpact Welder TIG and ARC Interview Questions and Answers for Experienced

The perfect welding technique depends on the specific project and materials being used.

• The perfect welding technique can vary based on factors such as the type of metal being welded, the thickness of the materials, and the desired strength of the weld.

• For TIG welding, a perfect technique involves using a non-consumable tungsten electrode to create a precise and clean weld on thin materials like stainless steel or alumi...read more

Yes, Tig welding uses gas to protect the weld pool from atmospheric contamination.

• Tig welding uses a shielding gas, typically argon or a mixture of argon and helium, to protect the weld pool.

• The gas creates a stable arc and prevents oxidation of the weld.

• Gas flow rate and composition are important factors in Tig welding process.

• Examples of Tig welding gas include pure argon for welding aluminum and a mix of argon and C

Mig welding stands for Metal Inert Gas welding, a process where a continuous solid wire electrode is fed through a welding gun and into the weld pool.

• Mig welding uses a shielding gas to protect the weld from atmospheric contamination.

• The wire electrode melts and fuses with the base metal to form the weld.

• Commonly used in automotive, construction, and manufacturing industries.

• Provides high welding speeds and can be used...read more
