[ 1 ] - EFFECT OF HEAT INPUT ON THE STRUCTURE AND PROPERTIES OF ALUMINIUM WELDMENT

The probable reasons for evolution of weld porosity and solidification cracking and the structure- property relationship in aluminium welds were investigated. Aluminium plates (1xxx series) were welded by Tungsten Inert Gas (TIG) welding process, 5356 filler metal was used and heat input was controlled by varying welding current (145A, 175A and 195A). The welded samples were examined under opti...
