CMT ADVANCED PULSE: JOINING HIGH-STRENGTH STEELS WITH LOW HEAT INPUT

While the positive cycles are alternated with the negative cycles during CMT Advanced, the CMT Advanced Pulse welding process combines CMT cycles with a negative electrode polarity and a pulse phase with positive polarity. The process achieves a higher deposition rate during the negatively poled phase with lower heat input. Pole reversal to the positively poled pulse cycles takes place in the short circuit.

ADVANTAGES OF THE APPLICATION

As well as higher heat input, the pulse phase gives the user the advantage of non-short-circuiting droplet transfer. The relationship between the positive and negative process cycles is freely selectable. CMT Advanced Pulse makes it possible to join high-strength steels with a sufficiently high deposition rate yet with low heat input.
