Solution Approach 1:

The solid brazing material is rotated during the application process, transforming the static contact into dynamic contact. This rotation allows the same contact area to continuously renew the material surface in contact with the workpiece, increasing the effective application amount without proportionally increasing frictional force and maintaining running stability

Inventive Principle:
