Vigilant Technologies Interview Questions and Answers

Projection welding is a type of resistance welding process used to join metal parts together.

• Projection welding involves passing a high electrical current through a small projection on one of the metal parts, creating heat at the contact point.

• The heat generated causes the metal to melt and form a weld nugget, joining the two parts together.

• This process is commonly used in automotive industry for welding nuts, bolts, and other fasteners onto metal parts.

• It is also used in man...read more

Parameters of welding include voltage, current, welding speed, and electrode size.

• Voltage: determines the heat input and penetration depth

• Current: controls the amount of heat generated

• Welding speed: affects the cooling rate and bead shape

• Electrode size: influences the weld pool size and penetration

• Gas flow rate: important for shielding the weld from atmospheric contamination

Teaching a robot involves programming it to perform specific tasks through a series of instructions.

• Start by defining the task or tasks the robot needs to perform.

• Write a program using a programming language that the robot understands.

• Test the program on the robot and make necessary adjustments.

• Repeat the process until the robot can successfully perform the task.

• Provide feedback to the robot based on its performance to improve its learning.

Spot welding is a type of resistance welding used to join metal sheets together by applying pressure and heat at localized points.

• Spot welding is commonly used in the automotive industry to join sheet metal components in car bodies.

• It involves passing an electric current through the metal sheets to generate heat at the welding point.

• The heat softens the metal, allowing it to fuse together when pressure is applied.

• Spot welding is a quick and efficient method for joining metal ...read more
