Leaf Stationary Spot Welder Projection Welding Machines For
Galvanized Sheets
Product Description
The metal leaf welding machine's welding action principle: Press
the start button and the equipment action will be completed by the
welding controller without manual intervention.Until welding point
is completed. Each welding head completes projection welding of 4
welding points. A total of 8 protrusions were welded in one
clamping process. Easy to ensure the welding quality of each
welding point. The welding pressure and welding current of each
welding head are independently adjustable.

Advantages
1) The formation of the weld nugget is always surrounded by a
plastic ring, isolating the molten metal from the air, and the
metallurgical process is simple.
2) The heating time is short, the heat is concentrated, so the heat
affected zone is small, and the deformation and stress are also
small. Usually, there is no need to arrange calibration and heat
treatment procedures after welding.
3) No need for filler metals such as welding wires and rods, as
well as welding consumables such as chlorine, ethylene glycol, and
hydrogen, resulting in low welding costs.
4) Simple operation, easy to achieve mechanization and automation,
low proficiency requirements for workers, and low labor intensity.
5) High productivity, low noise, and no harmful gases.
