Application of teaching-free six-axis welding robot in welding tower foot of transmission line

Aiming at the process test of teaching-free six-axis tower foot welding robot in welding tower foot of transmission line,the full-automatic GMAW was carried out on the main weld of tower foot structural components with removed stiffener.The welding parameters were verified,and the deformation,weld appearance and weld size of the welded workpiece were inspected.The production efficiency of teaching-free six-axis tower foot welding robot was compared with that of original manual welding.The research results showed that the teaching-free six-axis tower foot welding robot had good formation of weld,beautiful weld appearance with fish scale pattern,weld foot size met the requirements,and the efficiency was significantly higher than that of manual welding,which was of great significance to the subsequent automation and intelligent upgrading of transmission line tower foot welding.
