The article presents results of comparative A-TIG welding tests involving selected unalloyed and fine-grained steels, as well as high-strength steel WELDOX 1300 and austenitic stainless steel AISI 304L. The tests involved the use of single ingredient activated fluxes (Cr2O3, TiO2, SiO2, Fe2O3, NaF, and AlF3). In cases of carbon and low-alloy steels, the tests revealed that the greatest increase in penetration depth was observed in the steels which had been well deoxidized and purified during their production in steelworks. The tests revealed that among the activated fluxes, the TiO2 and SiO2 oxides always led to an increase in penetration depth during A-TIG welding, regardless of the type and grade of steel. The degree of the aforesaid increase was restricted within the range of 30% to more than 200%.

New Variant

A-TIG welding is a new variant of high-efficiency TIG weld technology, the weld penetration can be improved by using surface activating fluxes. In the present work, 12 mm thick stainless steel plates were welded by A-TIG method utilizing self-developed oxide-based composite activating flux. Results showed that for 12 mm thick stainless steel plates, weld joint of full penetration and one-side welding with back formation and good weld appearance could be achieved by A-TIG welding. Furthermore, compared with traditional TIG welding, the microstructure of A-TIG weld was finer, directivity of dendritic crystals near weld bond line was weaker, and mechanical properties of weld joints was also superior.
