Abstract (English):
The results of the investigations of susceptibility to hot cracks formation at welding of alloy 1151 in comparison with alloys 1201 and 1460 are shown. The character of alloy 1151 is a possibility of hot crack propagation both through a metal seam and through the area of a seam fusion with basic metal. The durability of welds of alloy 1151 carried out by fuse welding and friction welding with blending exceeds the durability of alloys 1201 and 1460. Corrosion resistance of welds of alloy 1151 exceeds considerably the corrosion resistance of compositions of alloy 1201.

Keywords:
argon-arc welding, friction welding with blending, wrought aluminum alloys, welds, welding wire, weldability, hot cracks, tests at increased temperatures, durability indices, stress corrosion.
