Fig. 5. Dependence of the relative length of oxide inclusions (Δo.v.) in the welded joints of the AMg6 alloy on the thickness of
the flux (s) applied to the tape.
The obtained results of mechanical tests of welded joints of the AMg6 alloy obtained
by TIG welding using a conventional tape backing and flux tape are presented in Table 4. In
accordance with the results obtained, the joints made by welding with a flux tape without
cutting the welded edges have higher strength properties (see table 4, no. 2 and no. 6). This
effect, apparently, can be explained, firstly, by the effective removal of oxide inclusions and
pores with a flux tape and, secondly, by a small fraction of the participation of the filler metal in
the weld.
