Increasing the productivity of TIG welding of steels and aluminium alloys by adding ultrafine particles of activating fluxes

The results of investigations of the effect of ultrafine activating fluxes on the properties of the welding arc and the formation of welded joints in welding with direct in alternating current to increase the productivity of automatic argon-shielded arc welding of steels in aluminium alloys and improve the quality of welded joints are presented.
