Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area. It works by contacting copper alloy electrodes to the sheet surfaces, whereby pressure and electric
the arm resistance of spot-welding machine including welding electrode''s and load''s resistances are taken as 100 µ, 800 µ respect ively.
Programmable Charging Parameters: Many advanced energy storage spot welding machines offer programmable charging parameters that allow operators to set specific limits on the charging current. These parameters can be adjusted based on the material being welded, the desired weld quality, and the machine''s capabilities.
In achieving a perfect weld, a range of variables come into play: Electrode Force: Dictates the quality of the weld. Squeeze Time: The lull between applying force and initiating the current. Welding Time: The span during which the current actively flows. Holding Time: Period for the nugget to solidify.

6 · Once you have everything, start by creating the copper wires by stripping them to size and shaping them into electrodes. Then, attach the transformer to the electrodes and connect it to the switch. Finally, connect the steel plates to the electrodes, and you''re ready to test out your new spot welding machine.
When operating an energy storage spot welding machine, it is important to select the appropriate "control mode" based on different products and materials to achieve the best welding results. The feedback control modes of energy storage spot welding machines mainly include "constant current," "constant voltage," and "constant power."

When the workpiece and the electrode are constant, the resistance of the workpiece depends on its resistivity. Therefore, resistivity is an important property of the material being welded. Metals with high resistivity have poor conductivity (such as stainless steel). Metals with low resistivity have good conductivity. (Such as aluminum alloy).
