Description
Summary:The E.O. Paton Electric Welding Institute has developed technology and specialised equipment for automatic CO sub 2 welding fillet overhead welds in lap, T and fillet joints. Welding is carried out with a pulsed arc with free metal formation with a current of 180-300 A. The method enables fillet welds with a leg length of 13 mm to be produced in a single pass in the overhead position. Welds with a long leg length can be produced by multipass welding. The welded joints contain no undercutting and excess metal and transition to the parent metal is smooth. [From Russian].
