KARWELD is KARMET’s complete robotic laser welding solution, developed to make welding automation simpler, more flexible and more efficient.
The system combines a collaborative robot, fiber laser technology, robotic welding head, automatic wire feeding and a professional welding table within a fully enclosed safety cell.
Thanks to intuitive hand-guided teaching, operators can quickly create new welding paths without advanced robot programming knowledge. Once taught, KARWELD performs repetitive welding operations with consistent precision, stable quality and high productivity.
Designed for manufacturers looking to reduce dependency on skilled manual welding, increase production capacity and achieve repeatable quality, KARWELD provides a practical transition from manual welding to robotic automation.
Engineered, integrated and tested by KARMET in Bulgaria.
