Fronius develops CMT Cycle Step for improved welding control

Fronius offers the Cycle Step process variant for the cold metal transfer (CMT) welding process, which allows users to set both the number of individual droplets and the pause time between cycles. The extent of the resulting material removal in a sequence can also be set.

The result is a heat-reduced bead with clear ripples and a high degree of reproducibility, says the company. With minimal, controllable heat input, the process is suitable for use during position welding with gap tolerances. The clear rippling of the weld seam is useful for high-quality visible seams. The process enables the smallest fixation points to be welded, making it an alternative to spot welding guns, the manufacturer reports.

The process can be used to weld galvanized sheets or to produce hold points for supporting bonded joints. Overlay welding and applications in additive manufacturing also are possible.
