| Summary: | In this article, there is some special features of obtaining
dissimilar butt-welded and lap-welded joints for various
material systems. The scheme for obtaining butt-welded joints
of aluminum to steel with tool displacement is analyzed.
The analysis of quality and structure of welds that were
manufacturing using this scheme is being conducted. The
transverse micro-section of obtained specimen of the weld of
aluminum alloy AMG6 to stainless steel 12H18N10T of 2 mm
thickness at a welding speed of 50 rpm and a transverse speed
of 50 mm/min with a tool displacement of 0,2 mm to steel part
are investigated. Mutual invasion of metals to a depth of 3,2
mm and steel inclusions in an aluminum alloy of up to 0,3 mm
in size are observed in the weld seam. |
