AHP HYDRAULIKA, a.s. is producer of the boring bars
of various sizes. The friction welding technique of bar body
welding with high noble tools is used.

This technique is
more advantageous in comparing with the standard
welding methods because of:
- very high quality of homogenous weld,
the breaking strenght of the weld is the same or higher
than in the base material
- the highest alignment of the welded parts
- the same parameters of the repeated welding processes
- effective monitoring of the welding process
- high productivity
