Motoman Robots Arc Welding
Weld-Intensive Brackets for Heavy Vehicles
Motoman's solution is 500% faster than the manual process. Average cycle time is 5 minutes, 55 seconds - 1.39% higher than requirement.
- Aggressive cycle time of 12 -16 welds per part in six minutes - equates to 10 parts per hour, 5,300 per month. Manual process required approximately 30 minutes per part.
- Weld three or four brackets on part approximately 2,210 mm (87") long, weighing 122.4 kg (270 lbs), with walls of .625" thick mild steel.
- Large welds, some with 25.4 mm (1") bead width, requiring multiple weld passes with large weaves, using .045" solid wire.
- Redo all weld processes from manual welding with .052" fluxcore wire to accommodate automatic welding with .045" solid wire.
- Weld inconsistent parts that are .5 mm - 2.5 mm (.020" - .100") out of tolerance.
- Improve weld repeatability and dimensional tolerances over manual clamping/welding process.
