Motoman Robots Welding

Two Motoman HP50-20 robots equipped with extended reach torches simultaneously perform heavy-deposition welding on large preheated, pre-tacked frame weldments fixtured on a two-axis drop-center servo tilt/servo rotate positioner.Oil Industry Equipment

Robotic system meets or exceeds all project goals and objectives. It significantly improves welding productivity and throughput, while reducing direct labor and increasing safety. Dual robots completely weld parts through all three stages in 4-6 hours. Parts only need to be preheated before each stage. Parts formerly required 3-5 days to complete, due to need to send part back to oven multiple times for preheating/reheating. System requires one operator versus three to four manual welders, allowing skilled welders to be redeployed elsewhere in the plant. Robotic welding improves safety by eliminating workers’ need to reach into tight areas on heated parts to weld manually. Flexible positioner improves productivity and safety by eliminating the need for excessive manual handling and/or part repositioning using crane and hoist. Robotic welding improves welding quality, consistency and aesthetics.
