The cracking which sometimes occurs in the weld bead and in the adjacent metal is the most troublesome problem which arises in the fusion welding of aluminum and its alloys.This work was carried out on binary alloys of aluminum with silicon, copper, magnesium, zinc, iron, manganese and chrome, all the alloys being prepared from aluminum with the purity of 99.99% and alloying elemments of the highest purity obtainable.The results obtained are summarized as follows:1) The welding crack of the oxyacetylene process is severer than that of the Argon-arc process.2) Cracking differs with the support distance of restraint.3) Aluminum alloys with iron, manganese and chrome are not subject to cracking by oxyacetylene process welding under very severe condition of restraint.4) Binary aluminum alloys with wide range of solid solution such as magnesium, copper, silicon and zinc are very sensitive to cracking. The cracking becomes severe with the addition of these alloying element at first and after reaching a maximum point decreases till its reaches a constant value.
