It was found that no hot cracks were observed when welding of alloy 2024 started at 10 mm from edge of the strip . Preheating of 7075 reduced the length of the cracks significantly . Postweld heat treatment increased joints efficiency to 82% of the tensile strength of base material UR - http://172.23.153.220/th.pdf ER -
