| A flexible contact tube adapted to be accommodated with any conventional Gas Metal ARC (GMA) welding torch adapted for ARC rotation, said tube of comprising slots of length 3pd/8 to 5pd/8, at spacing of d/3 to d/2.5 (where ‘d’ is the inside diameter of said contact tube). A system for ARC rotation comprising the flexible tube adapted to be accommodated with any conventional Gas Metal ARC (MGA) welding torch; the torch body; contact tip; means for attachment of the said tube between the torch body and contact tip; means for providing lateral motion to the contact tip and means for moving the contact tube. The said system for ARC rotation yields improved weld bead geometry and penetration characteristics. | |
