Before starting the operation of the intermediate frequency spot welding machine, it is necessary to adjust the parameters, starting from the selected electrode pressure, pre pressing time, welding time, and maintenance time, to determine the shape and size of the electrode end face of the intermediate frequency spot welding machine.
The welding parameters of the intermediate frequency spot welding machine are determined by the material and thickness of the workpiece, and are selected based on the welding conditions of the workpiece material. Then start the test piece with a smaller current, gradually increase the current until splashing occurs, and then reduce the current appropriately to no splashing. Check whether the pulling and shearing degree, nugget diameter, and penetration depth of a single point meet the requirements, and adjust the current or welding time appropriately until the requirements are met.
When welding low carbon steel and low alloy steel, welding time is secondary compared to electrode pressure and welding current. When determining the appropriate electrode pressure and welding current, adjusting the welding time to achieve satisfactory welding points.
