Fundamental Study on Weld Formation Phenomena of High Speed Lap Seam Welding (5th Report)

Calculation of Temperature Distribution in the Plates

Abstract

Temperature distribution in seam welding is calculated assuming that the current path in a plate is one shown in Fig. 1 and welding current distributes uniformly in the current path.
It is made clear that the approximate temperature distribution can be calculated on the above men-tioned assumptions and that the contact resistance at the weld interface plays an important role in weld formation.
