An investigation on the temperature distribution in thinwalled cylinders during welding up of wear-proof layers

This paper describes an attempt to find the space and timewise temperature-distribution in a thinwalled cylinder during building up by welding several layers on top of each other. From the exact one-dimensional solution (thin ring) we found an approximate solution for the cylinder. The approximation used is made possible by the fact that in practice the angular velocity (which is related to the welding speed) is great with respect to the relaxationtime of heat in the material. A number of experiments are given to verify the theoretical results.
