EXTREME ENGITECH Interview Questions and Answers

Welding defects include porosity, cracks, lack of fusion, and undercut. They can be detected through visual inspection, dye penetrant testing, ultrasonic testing, and radiographic testing.

• Common welding defects include porosity, which appears as small holes in the weld, cracks, lack of fusion where the weld does not fully bond with the base metal, and undercut where the weld metal is not properly fused to the base meta...read more

There are various types of materials, with HR (Hot Rolled) and CR (Cold Rolled) being two common types in engineering.

• Types of materials include metals, plastics, ceramics, composites, etc.

• HR (Hot Rolled) materials are processed at high temperatures, making them easier to shape but less precise in dimensions.

• CR (Cold Rolled) materials are processed at room temperature, resulting in higher strength and better surface fi...read more

Different types of welding include MIG, TIG, stick, and flux-cored welding, each with unique characteristics and applications.

• MIG (Metal Inert Gas) welding uses a wire electrode and shielding gas to create a strong bond between metals.

• TIG (Tungsten Inert Gas) welding uses a non-consumable tungsten electrode and inert gas to produce high-quality welds.

• Stick welding, also known as Shielded Metal Arc Welding (SMAW), uses ...read more
