Abstract
The article offers a presentation of robotized GTA welding (TIG) of metal sheets 1-mm thick without filler metals. This research work focused on achieving the maximum possible travel speed of overlapping and edge joint welds. The results demonstrated that welding speeds ranging from 7 to 12 mm/s for S235JRG2 steel welds and from 10 to 16 mm/s for X5CrNi18-8 steel welds were similar to those obtained by means of plasma arc welding.
