House Of Believe Interview Questions and Answers

MIG and spot welding are common welding techniques used in production. Welding defects can occur and need to be remedied.

• MIG welding, also known as Gas Metal Arc Welding (GMAW), uses a consumable wire electrode and shielding gas to join metal pieces together.

• Spot welding is a resistance welding process that uses two copper alloy electrodes to apply pressure and heat to join metal sheets.

• Common welding defects include porosity, undercutting, lack of fusion, and distortion.

• Reme...read more

Projection welding is a type of resistance welding where two or more metal parts are joined together by applying pressure and passing an electric current through the contact points.

• Projection welding is commonly used in automotive and appliance manufacturing.

• It is suitable for joining parts with projections or embossments.

• The projections on the parts concentrate the heat and pressure, ensuring a strong weld.

• The process involves placing the parts between two electrodes and app...read more
