Pulse Welding


Pulse welding is an advanced welding technique that offers several advantages over traditional continuous welding methods. It involves the use of rapid, intermittent pulses of current during the welding process.

This article will provide an in-depth understanding of pulse welding, its benefits, applications, and the key factors to consider when using this technique.

What is Pulse Welding?

Pulse welding is a process where the welding current alternates between high and low levels in a controlled manner. The high current level, known as the pulse peak, generates the heat necessary for melting the metal.

The low current level, known as the background current, allows the weld pool to solidify and cool slightly before the next pulse. This pulsating current creates a more precise and controlled heat input, resulting in improved weld quality and reduced heat-affected zone.
