Motoman Robots Arc Welding
Steel Cabinets and Doors
Flexible robot system welds two different sizes of pre-tacked steel cabinets, including doors. System welds parts in well under the required cycle time. Robotic welding improves productivity, welding consistency and part quality. NOTE: Prior to implementing robot cell, customer was out-sourcing production to China, but was having quality issues. Robotic welding cell improved welding and overall quality, enabling production to be brought in-house.
- Provide flexible system to weld two different sizes of pre-tacked steel cabinets, including doors.
- Achieve cycle time of approximately 3-4 minutes per part.
- Improve productivity, weld consistency and part quality.
