In this project I am making a DIY spot welding machine to be used for building battery packs with 18650 lithium ion cells. I also have a professional spot welder, model Sunkko 737G which is around $100 but I can happily say that my DIY spot welder out-performs the professional spot welder by outputting higher currents and being able to solder pure …

Shortly after the maximum current is reached, the force is increased to press the sheets against each other (forging effect). Similar programmes are mandatory for welding in the aerospace industry (Figure 4500.02.01). Guidelines are available for the spot welding of a large number of aluminium alloys.

Layout The Cells for Spot Welding. Now that we know our battery pack will be in 3S2P configuration, we can put the cells together. We have 2 cells each in the parallel groups ( 5000 mAh x 2 = 10000 mAh) and we have 3 of those groups in series. To begin, place the first parallel group of 2 cells positive side up.

There are at least seven important resistance-welding processes. These are: Flash welding. High frequency. Percussion welding. Projection welding. Resistance seam welding. Resistance spot welding (most common process), involves the use of water-cooled copper electrodes which are clamped with the sheets into place.

Spot welding, a form of resistance welding, is a process used to join two or more metal sheets together by applying pressure and heat to the weld area. It involves the use of electrodes, typically made of copper, to apply an electric current to the metal pieces. This current generates heat due to the resistance in the materials, causing the ...

Amperage measures the strength of the electrical current, with its primary effect on welding being the melt-off rate of the electrode and the depth of penetration into the base material. Wire feed speed (WFS), another of the welding variables, controls amperage and the amount of weld penetration. WFS and current are directly related: as one ...
