Abstract

The method of butt welding of very thin 0.3 mm thick aluminum sheets at very high welding speed (6000 mm/min) using ordinary TIG welder were newly developed. The process are as follows.
Polarity is DCEN. The aluminum sheets were put in between 30 mm thick copper plates. By this method the aluminum sheets were butt welded up to 0.2 mm and bead welded up to 0.1 mm thick by bead on plate successfully. At comparatively low welding speed (500 mm/min), pushing roller had better to be added.
Generally, welding heat input at high welding speeds are smaller than those of low welding speed. The appearance of successful welding are shown in photgraphs.
