thick. Calculate the longitudinal shrinkage that occurs during welding.

Answer 1

The longitudinal shrinkage that occurs during welding is 381.5625 mm.

Step-by-step explanation:

To calculate the longitudinal shrinkage that occurs during welding, we need to use the formula SL = (3051L)/(tK), where SL is the shrinkage, L is the length of the weld in millimeters, t is the thickness of the plate in millimeters, and K is the welding current in amperes.

Given that the welding current is 125 amp, the length of the weld is 250 mm, and the plate thickness is 16 mm, we can substitute these values into the formula.

SL = (3051 * 250) / (16 * 125) = 381.5625 mm

Therefore, the longitudinal shrinkage that occurs during welding is 381.5625 mm.
