In order to evaluate the wealdability performance of TIG on stainless steel plate of no. 301 & 316 the calculated parameters of the weld pool demonstrate due to the more concentrated heat flux and higher flow velocity of the constricted arc the pressure on the surface of melted steel is increased. Also the convective and conductive components of the power flux from the arc to the work piece are larger. As the result, the weld pool is deeper and, at the same time, the HAZ is much smaller in case of the constricted are. The simulation model is found to be in good agreement with experimental results for the arc temperature and enable to calculate optimal parameters of constricted arc welding result as predicted in simulated results. Therefore, it can be used to form technical demands for the control of the heat flux depending on the welded material and it's thickness. It supports increasing quality and predictability of the welding seams. The modification of the model, described in the simulation method, provides more accurate precise result.
