Welding and Quality Engineer Interview Questions and Answers

MIG and TIG are two types of welding processes. MIG uses a consumable wire electrode and TIG uses a non-consumable tungsten electrode.

• MIG stands for Metal Inert Gas welding and TIG stands for Tungsten Inert Gas welding.

• MIG welding uses a consumable wire electrode that melts and fuses two pieces of metal together.

• TIG welding uses a non-consumable tungsten electrode to create an arc that melts the metal and fuses it together.

• MIG welding is faster and easier to learn than TIG we...read more

Dye penetrant test is a non-destructive testing method used to detect surface defects in materials.

• Clean the surface to be tested

• Apply penetrant to the surface

• Remove excess penetrant

• Apply developer to draw out penetrant from defects

• Inspect for defects under UV light

• Evaluate and classify defects based on standards

• Commonly used in welding and manufacturing industries
