Larsen & Toubro Limited Foreman Interview Questions and Answers for Experienced

Common welding processes include MIG, TIG, Stick, and Flux-Cored welding.

• MIG (Metal Inert Gas) welding uses a wire electrode and shielding gas to join metal.

• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and filler metal to join metal.

• Stick welding uses a consumable electrode coated in flux to join metal.

• Flux-Cored welding uses a wire electrode with a flux core to join metal.

Tests conducted on welding joints

• Visual inspection

• Dye penetrant testing

• Radiographic testing

• Ultrasonic testing

• Magnetic particle testing

• Tensile testing

• Bend testing

Submerged arc welding is a process where an arc is maintained between a consumable electrode and the workpiece under a blanket of granular flux.

• The process is used for welding thick sections of steel.

• The granular flux shields the weld from atmospheric contamination.

• The consumable electrode is continuously fed into the weld pool.

• The process is commonly used in shipbuilding, pipeline construction, and pressure vessel fab

Defected welding joints can be rectified through a process of cutting, grinding, and rewelding.

• Identify the type and extent of the defect

• Cut out the defected portion of the joint

• Grind the edges of the remaining joint to prepare for rewelding

• Reweld the joint using appropriate welding techniques and materials

• Perform non-destructive testing to ensure the quality of the repaired joint
