Robotic Simulation Engineer Interview Questions and Answers

Clinching is a process of joining two metal sheets by deforming them without using any external heat or fasteners.

• Clinching is a cold joining process that uses a punch and die to deform the metal sheets.

• It creates a strong mechanical interlock between the sheets, eliminating the need for additional fasteners.

• Clinching is faster and more cost-effective than spot welding, as it does not require any consumables or special equipment.

• It also produces less heat and does not create ...read more

Gun selection for spot welding depends on factors like material thickness, joint type, electrode size, and welding current.

• Material thickness determines the required electrode force and current capacity.

• Joint type affects the electrode shape and size needed for proper contact.

• Electrode size should match the weld area and current capacity.

• Welding current is determined by the material thickness and desired penetration.

• Examples of gun types include air-cooled, water-cooled, and ...read more

Self-piercing rivets are fasteners that do not require pre-drilled holes and are commonly used in automotive and aerospace industries.

• Self-piercing rivets are made of high-strength materials such as aluminum, steel, or titanium.

• They are used to join two or more sheets of material together without the need for pre-drilled holes.

• Self-piercing rivets are commonly used in the automotive and aerospace industries for their strength and durability.

• Examples of applications include jo...read more

The selection of a gun for stud welding depends on the type of material being welded and the size of the stud.

• Consider the diameter and length of the stud

• Choose a gun with appropriate power and capacity

• Select a gun with the correct tip for the material being welded

• Ensure the gun is compatible with the welding machine being used
