MW-Rapid with Pulse

MW Rapid-Pulse

MW-Rapid with Pulse offers all the benefits of Pulse MIG/MAG welding, with all the added benefits that go along with higher deposition rates and deeper penetration. This new generation of higher deposition pulse MIG welding offers many benefits over tradition pulse MIG welding characteristics.

The process is easy to learn, even for new welders, owing to quick digital process control, very little spatter, and fewer undercuts. Even with lengthy stick-outs, the weld is faultless and at high power levels, excellent gap bridging is achievable.

Increased Welding Speed

When high dynamics are added to pulsation, an intensely concentrated arc is produced, which enhances the fluidity, pression of transfer and wetting of surface, permitting the user to move the MIG gun faster and saving time.

Standard Pulse vs MW Rapid-Pulse

Increased Deposition Rate

In standard pulse, the high dynamics of the MW Rapid-Pulse arc allow for higher wire speed while maintaining the existing volume. The weight of deposit in the unit of time, kilograms per hour, grows according to the expansion of wire in the weld pool.

Reduced Heat Input

MW Rapid-Pulse is particularly well-suited to superior quality welding. Temperatures are lower and the heat affected zone is narrower implying that the mechanical and metallurgical qualities of the welds are significantly improved over standard pulse welding.

Improved Properties

For standard pulse, tensile strengths are substantially greater in the pure deposit and heat affected zone in standard pulse. Hardness and tensile strengths in MW Rapid-Pulse are consistent with the metal class of the base material, hence heat input has no effect on the welded material.

Deeper Penetration

Due to the wetting of the weld surface, the finished weld is smoother and as demonstrated in the figures above/beside, penetration is significantly higher when welding in MW Rapid-Pulse compared to standard pulse.
