Welder Trainee Interview Questions and Answers

There are four main types of welding: MIG, TIG, Stick, and Flux-Cored.

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

• TIG (Tungsten Inert Gas) welding uses a tungsten electrode and a shielding gas to create a precise and clean weld.

• Stick welding (also known as Shielded Metal Arc Welding or SMAW) uses a stick electrode and a flux coating to create a strong bond between two metal pieces.

• Flux-Cored welding uses a wire ele...read more

Pressure welding involves joining metals under high pressure, while non-pressure welding is done without pressure.

• Pressure welding is used for joining thick metals and requires specialized equipment.

• Non-pressure welding is commonly used for thinner metals and can be done with simple equipment like a soldering iron.

• Examples of pressure welding include friction welding and explosion welding.

• Examples of non-pressure welding include arc welding and gas welding.

Fraction welding is a welding process that involves joining two or more metal parts by melting and fusing them together.

• Fraction welding is also known as fusion welding.

• It involves the use of heat to melt and fuse metal parts together.

• This process is commonly used in the construction of pipelines, tanks, and other large metal structures.

• Fraction welding requires a high level of skill and precision to ensure a strong and durable weld.

• Common types of fraction welding include ga...read more

Spot welding is a type of welding process where two metal surfaces are joined together by applying heat and pressure at a specific spot.

• It is commonly used in the automotive industry to join sheet metal parts together.

• The process involves passing an electric current through the metal surfaces to be joined, which creates heat and melts the metal at the spot where the electrodes are placed.

• The electrodes then apply pressure to the melted metal, causing it to fuse together and f...read more
