Abstract
A submerged arc welding system includes a robot having a first arm connected to a second arm, and at least one wire supply. A welding torch is connected to a first end of the second arm of the robot. A wire motor is mounted to a second end of the second arm of the robot. The wire motor moves wire from the wire supply along a wire path to the welding torch. The system further includes a flux supply and a flux delivery system configured to move flux from the flux supply along a flux path to the welding torch.
Claims20
A submerged arc welding system for use with a robot having a base, a first arm rotatably connected to the base, and a second arm rotatably connected to the first arm, the submerged arc welding system comprising:
- a welding torch having a nozzle, the welding torch being connected to the end of the second arm of the robot;
- a wire supply;
- a wire path connecting the wire supply to the welding torch;
- a wire motor configured to move wire from the wire supply along the wire path to the welding torch, the wire motor being mounted to the robot at a location other than the second arm;
- a flux supply;
- a flux path connecting the flux supply to the welding torch;
- and
- a flux muffler disposed along the flux path, the flux muffler comprising a casing, and a conduit within the casing forming a vent chamber that is interior of the casing, the vent chamber having a vent for evacuating air from the flux path, the flux muffler further comprising a filter within the casing and exterior of the vent chamber and configured to capture flux fines.
A submerged arc welding system comprising:
- a robot including a first arm connected to a second arm;
- at least one wire supply;
- a welding torch connected to a first end of the second arm of the robot;
- a wire motor mounted to a second end of the second arm of the robot, the wire motor moving wire from the wire supply along a wire path to the welding torch;
- a flux supply;
- a flux delivery system configured to move flux from the flux supply along a flux path to the welding torch;
- and
- a flux muffler disposed along the flux path, the flux muffler comprising a casing, and a conduit within the casing forming a vent chamber that is interior of the casing, the vent chamber having a vent for evacuating air from the flux path, the flux muffler further comprising a filter within the casing and exterior of the vent chamber and configured to capture flux fines.
An automatic submerged arc welding system comprising:
- a welding torch having a nozzle;
- a flux supply;
- means for transporting flux from the flux supply along a flux path to the nozzle of the welding torch;
- a wire supply;
- means for transporting wire from the wire supply along a wire path to the nozzle of the welding torch, such that the flux path converges with the wire path at the nozzle;
- and
- a flux muffler disposed along the flux path, the flux muffler comprising a casing, and a conduit within the casing forming a vent chamber interior of the casing, the vent chamber having a vent for evacuating air from the flux path, the flux muffler further comprising a filter within the casing and exterior of the vent chamber and configured to capture flux fines.
