Cold Metal Transfer (CMT)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.
