Motoman Robots Arc Welding

Three Motoman HP20 robots equipped with tandem-arc GMAW torches perform heavy-deposition welding on construction crane outrigger beams fixtured on two MHT-3000 headstock/tailstock positioners using hydraulically clamped adjustable-length tooling.Crane Outriggers (Construction Equipment)

Flexible robotic solution meets or exceeds project goals and objectives, and can weld all required parts. Motoman system welds parts significantly faster than the 27-minute cycle time requirement. Some parts are welded in 13 minutes. Most parts average 17-18 minutes. Customer was able to bring all out-sourced production back in-house, saving time and money. Robotic tandem-arc GMAW system consistently produces high-quality heavy-deposition welds and enables skilled manual welders to be redeployed elsewhere in the plant.

Fixtures/Tooling Details

Motoman Robotics provided hydraulic clamping fixtures for the two headstock/tailstock positioners. A large spanner between the HS/TS faceplates is adjustable to accommodate various beam lengths. Two alignment clamps and two swing arms per fixture hold each part for welding. Fixtures include part-present and clamp open/closed sensors.
