What is a medium-frequency pulse? What types of welding are suitable for?

Medium-frequency pulse welding refers to pulsed arcs with frequencies between 30-500Hz. It features an arc compression effect, enabling concentrated and stable welding heat input. Its core advantages include:

Precise heat control: Short current adjustment cycle (0.125ms-1ms), suitable for heat-sensitive materials such as high-strength steel.
DC clustering effect: Reduces the heat-affected zone, maintaining the strength of the base material.
High adaptability: Supports welding materials with thicknesses from 0.1mm to 10mm.
Main application areas:
Automotive manufacturing: Welding of body sheet metal parts (doors, hoods, etc.), especially suitable for aluminum alloys and high-strength steel.
Power batteries: Precision welding of electrode tabs, avoiding incomplete welds or overheating.
Aerospace: High-precision structural component welding.
Home appliance manufacturing: Efficient welding of metal casings (refrigerators, washing machines, etc.).
