Last but not least, new materials and applications have opened up new performance standards and a wide range of applications for the MIG/MAG welding process, as has the increasing use of technically mature microelectronics and digital technology. Jobs with particular welding power requirements however call for a specialised variant of MIG/MAG welding: “TIME” welding. For very long weld seams with a large cross-section and a high deposition rate, the TIME process is currently the most economical solution.
This modern joining method satisfies increasingly stringent demands,. some of the most important of which are process stability, reproducibility and cost-effectiveness. The bundling together of specific material properties opens up a number of interesting possibilities. Material compounds impart to a component or product the desirable properties of the constituent materials. Previously, such results could only be achieved by mechanical means or by bonding. Of much greater interest, however, is the ability to use heat to join materials with differing properties. The main focus in this respect is on the joining of steel and aluminium, as this will be of particular interest to the automotive sector, where it could spawn a whole range of previously undreamt of innovations.
CMT Twin is based on the same setup as the tried-and-tested TimeTwin welding process: two power sources, one welding torch and two separate “leading” and “trailing” contact tips. Enhanced by the exceptional weld properties of CMT, CMT Twin scores top marks for its high welding speed and easy-to-use process control.
