Resistance Seam Welding creates a continuous welding spot between two overlapping flat sheets. The advantages compared to other methods are the simple handling, high productivity, and good energy efficiency without the use of filler material.  Process-related over-gauge is minimized by the Miebach welding head’s ability to deliver high-power at a constant transmission rate. The continuous development of these machines is responsive to the world of constantly evolving steel grades ensuring long term productivity.
