The project aim was to develop an automatic cutting module for cutting welding threads. The welding thread must be cut after each welding operation in order to remove the “flux” that appears on the thread. Today the operators cut the thread manually which is time consuming. Since this is the only operation that cannot be operated from the floor, it is crucial to find a solution for cutting the thread automatically.
Within the project we visited industries, studied the workflow, interviewed operators, performed theoretical usability analysis, risk analysis, concept development, calculations and documentation.
The final concept is using pneumatic power to cut the thread with a sharp blade (red on the rendering), inside of the brown copper pipe. The concept is applicable on ESABs existing product with minor changes on the copper pipes.
