Resistance welding, as a widely used metal joining technology in the manufacturing industry, completes the welding process in a predetermined local area between the electrode head and the welding workpiece through the principle of electric current heating. This technology not only covers various types such as spot welding, projection welding,copper welding machine, roll welding machine and butt welding machine,lithium spot welding machine, but is also favored for its efficient and precise welding effect.

The principle of resistance welding seems simple, but it actually involves multiple adjustable parameters, which have a direct impact on the welding results. Among them, eight factors such as welding current, welding time, welding force, contact resistance, material properties, surface coating, shape and size, and medium frequency resistance welding machine characteristics all play a decisive role in welding quality.

However, in actual operation, resistance welding also faces some challenges. Problems such as electrode degradation, sheet assembly and stamping tolerances, and electrode misalignment may affect the welding effect. In addition, uneven current distribution during single-sided welding and shunting effect in multiple welds are also difficult problems that need to be overcome in resistance welding. At the same time, thermal expansion and contraction phenomena cannot be ignored, which may have an adverse effect on the strength and stability of the welded joint.

In summary, although resistance welding has many advantages, it is still necessary to pay attention to the influence of various factors in actual operation to ensure the quality and effect of welding. By continuously optimizing welding parameters and processes, we can better tap the potential of resistance welding and contribute to the development of the manufacturing industry.
