Abstract
TIG welding equipment, comprising a first articulate robot having a first arm, a TIG torch holding means holding a TIG torch at a specified position so that the TIG torch can perform a weaving operation, and a filler wire guide moving means formed so as to surround the TIG torch holding means and holdingly moving a filler wire guide in Z-axis direction.
Claims7
A TIG welding apparatus for performing a TIG welding process on a surface of a workpiece while supplying a filler wire from a filler wire guide to a space to generate an arc therein between a TIG torch and said workpiece, thereby forming a bead on said surface of said workpiece, said TIG welding apparatus comprising:
- an articulated robot for causing said TIG torch to make a weaving action to move toward and away from said surface of said workpiece while causing said TIG torch to follow said surface of said workpiece;
- and
- filler wire guide moving means held by said articulated robot, for moving said filler wire guide toward and away from said surface of said workpiece.
A TIG welding method for performing a TIG welding process on a surface of a workpiece while supplying a filler wire from a filler wire guide to a space to generate an arc therein between a TIG torch held by an arm of an articulated robot and said workpiece, thereby forming a bead on said surface of said workpiece, comprising:
- causing said TIG torch to make a weaving action to move toward and away from said surface of said workpiece while causing said TIG torch to follow said surface of said workpiece;
- and
- moving said filler wire guide in a direction opposite to a direction of said weaving action of said TIG torch.
A TIG welding apparatus for performing a TIG welding process on a surface of a workpiece while supplying a filler wire from a filler wire guide to a space to generate an arc therein between a TIG torch and said workpiece, thereby forming a bead on said surface of saidworkpiece, said TIG welding apparatus comprising:
- TIG torch moving means held by an arm of an articulated robot, for causing said TIG torch to make a weaving action to move toward and away from said surface of said workpiece;
- and
- filler wire guide holding means for holding said filler wire guide on said arm of said articulated robot.
