The customer's requirements were met through a short series of tests on original components with a Frontpull torch system and the application of the microMIG-cc process. Based on the recommendation of the expert team, the vertical-down position (PG) was selected as the weld joint position. The filler material used was 0.8 mm steel, with a 92 % Ar + 8 % CO₂ inert gas. With the subsequent transfer of knowledge into the actual production a welding speed of 130 cm/min was achieved and the high quality of the joint confirmed. 

In preparation for the future production of aluminum cabinets further test welds were performed on prototypes. Here, too, the selected method and the recommended welding position delivered convincing results.

Following the example of SKS Welding Systems GmbH in Germany, the welding laboratories of the subsidiaries are equipped with robot rotary tilting table combinations that allow simulating almost any conceivable component positions. The availability of the necessary components for the processes makes it possible that all SKS arc welding processes can be simulated in a very short time. Different torch and wear part geometries allow for accessibility studies on the actual workpiece. The in-house metallurgical department provides microsections to review customer requirements and irregularities within the weld seam. A high speed camera is also available to establish the best process parameters for special applications. 

The results of these investigations are discussed in detail in test reports and made available to the customers. In addition to the process recommendation and the simple transfer of the results into series production they also help saving time and costs as there is less staff and time required to determine the process parameters on site.
