A-TIG welding of stainless steel up to 12 мм thick with full penetration
Dmytro Kovalenko
ІЕЗ ім. Є.О. Патона НАН України. 03150, м. Київ, вул Казимира Малевича, 11.It is known that the use of A-TIG welding (TIG welding over an activating flux layer) significantly increases the arc penetration capacity. One of the optimal applications of the A-TIG process is the welding of flat welded structures or pipes (including orbital ones) up to 6 mm thick.
The E.O. Paton Electric Welding Institute (PWI), in collaboration with AICHI SANGYO (Japan), conducted experimental studies of A-TIG welding of 10 mm thick 304 stainless steel. PATIG S-A activating flux in the form of an aerosol can (developed by the PWI) and FIBACK optical fiber backing tape (developed by AQUASOL CORP., USA) were used.
It was shown that when using automatic A-TIG welding of butt joints made of 10 mm thick stainless steel, it is possible to obtain high-quality welds in a single pass without edge preparation and with full penetration. The possibility of similar use of A-TIG welding for thicknesses of 12 mm was also demonstrated.
