IPM is a unit describing rate of motion in which context?

• A. Inches per minute
• B. Miles per hour
• C. Meters per second
• D. Kilometers per hour

Answer: (A)

IPM stands for Inches Per Minute and is used to describe the travel speed of the welding torch or electrode along the joint. It tells you how many inches of progress you make in one minute, which is the practical, fine-grained scale for welding in everyday shop practice. Using inches per minute makes sense because welds are laid out in inches and the typical travel speeds are on the order of tens to hundreds of inches per minute, a range that directly relates to bead shape, penetration, and heat input. Other units like miles per hour, meters per second, or kilometers per hour describe much larger or metric speeds and aren’t convenient for the precise, small movements involved in welding travel. So the correct context is the rate at which the weld path advances, measured in inches per minute.
