Pulse welding is a technique where the welding current alternates between a high peak current and a lower background current. This controlled fluctuation provides several important advantages during the welding process.
The high peak current helps achieve proper penetration and allows the arc to stabilize, while the lower background current reduces heat input and minimizes spatter.
The main functions of pulse in welding include improved control of heat, reduced distortion, better weld appearance, and suitability for thin materials. Pulse also enhances metal transfer, giving a smoother and more stable arc, especially in MIG and TIG welding. Overall, pulse welding enables higher-quality welds with better efficiency and consistency.
