Special spot welding machine for energy storage

What is a portable spot welder?

A Portable Spot Welding Machine is mainly used in the welding of nickel sheets for cylindrical batteries like 18650. It has a built-in high-rate polymer power cell with a maximum output current of up to 639A, allowing it to weld thousands of points after being fully charged.

What is a Mesh Straightening Machine called?

This Mesh Straightening Machine is manufactured with modern tools and technology and therefore able to eliminate the minutest spot deflection. It is available with adjustable lengths of arms that suit your needs. It has a shock-proof body, which never creates any trouble in your operations.

What is a spot weld?

This method of spot weld fabrication is generally known as the automated method. The spot weld created has an indented surface caused by the pressure applied through the electrodes. A circumferential notch is also created when a spot weld forms between the two metal sheets. 1 4.1. Schematic of spot welding (HAZ is the heat affected zone).

What is spaced spot welding?

Spaced spot welding is realized by placing several spot welding at a certain overlap in order to achieve a seam weld. The length of the seam is scalable, but the heat input is very high because for each spot all process phases of spot welding have to be passed through. This may lead to distortion or thermal damage of the parts.
