To the Technology of Laser Welding of Aluminum with Titanium

Abstract:

The results of experimental study of laser welding alloys based on aluminum and titanium an intermediate composite Al+Ti insert obtained by explosion, using nanopowder additives and plastic deformation of the aluminum seam are presented. Morphologically high-quality welds have been obtained both in the welding of the aluminum plate and of the titanium one with the corresponding parts of the insert. It was found out that breakdown of the joint in the tensile test occurred along the aluminum part of the insert, which had a lower tensile strength than the titanium. The use of the nanomodifier without plastic deformation increases the strength of the weld joint by about 10% compared to the unmodified compound. The use of nanomodifying and strain hardening can significantly increase the tensile strength, the value of which is more than 97% of the strength of alloy (AA1135). The carried out experiments on laser butt welding of plates made of aluminum alloy 1424 systems Al-Mg-Li-Zr-Sc with their subsequent plastic deformation have confirmed the effectiveness of strain hardening of weld joints of aluminum alloys.
