Dell Production Engineer Interview Questions and Answers

Plasma welding uses a high-temperature ionized gas to melt and join metals together.

• Plasma welding involves creating an electrical arc between the workpiece and the electrode, ionizing the gas to form plasma.

• The high temperature of the plasma melts the metals being welded together.

• Plasma welding is commonly used for precision welding of thin materials or in applications where a high level of control is needed.

• Examples ...read more

Brazing welding is a joining process where a filler metal is melted and distributed between two or more close-fitting parts by capillary action.

• Brazing involves heating the base metals to a temperature above 450°C but below their melting point.

• The filler metal, usually in the form of a wire or preformed shape, is then melted and flows into the joint by capillary action.

• The filler metal must wet the base metals and form...read more

Line balancing is the process of assigning tasks to workstations in a way that evens out the workload and maximizes efficiency.

• Involves distributing work evenly among workstations

• Minimizes idle time and bottlenecks

• Helps improve productivity and reduce production costs

• Example: In an assembly line, tasks like welding, painting, and assembly are balanced to ensure smooth flow

Types of muda in production engineering include overproduction, waiting, transportation, processing, inventory, motion, and defects.

• Overproduction: Producing more than needed, leading to waste of resources.

• Waiting: Delays in production due to inefficient processes or lack of coordination.

• Transportation: Unnecessary movement of materials or products, increasing lead time.

• Processing: Unnecessary steps or complex processe...read more
