Abstract
In this paper, the ATIG welding technology, a variation of the TIG welding process with an activated flux, was presented. An experimental investigation of an innovative flux based on a mixture of nano and micron oxide particles in solvent was shown. The zeta potential of the flux, the macro test, the microstructure and microhardness test were performed. Also, based on the obtained results, a model of the liquid metal flow in the weld metal is shown, where the increase in depth occurs due to a change in the direction of liquid metal flow from the edge to the middle of the weld metal. It has been shown that the mixture of nano and micron particles has the highest efficiency, due to the grinding effect of agglomerated nano particles.
