Both the heat-affected zones and the total heating of the part are significantly lower with laser welding over arc or plasma welding. Laser welding allows adjustment, control and monitoring of joints to the highest degree. The identical joints that can be achieved is a direct result of this control, which contributes to the advantage of laser welding. Because of these identical joints, no costly and time consuming post-processing is needed. We have two laser welds where the TruLaser 5020 can handle slightly larger pieces.

The short-circuit current can be kept relatively low in the CMT process. Since the wire electrode is retracted the short circuit can be broken by controll. Because of these two features almost fully spray-free welding and solder joints is conceivable. The joints becomes completely spray-free in normal focal position. This means that no expensive and time-consuming post-processing is required.
