Analysis of thermal efficiency of energy storage welding machines

The energy storage welding machine is also a type of resistance welding equipment, which conducts resistance heat from the high temperature zone to the low temperature zone and belongs to the internal heat source. Therefore, the heat loss is very small and the thermal efficiency is very high. High thermal efficiency: Arc welding utilizes an external concentrated heat source to transfer heat energy to the welded part.

The weld seam of resistance welding needs to condense and crystallize under the influence of external pressure, which has the characteristics of forging and belongs to the scale of pressure welding. Therefore, it is more prone to defects such as shrinkage, porosity, and cracks, thus obtaining a dense weld seam.

Working principle of energy storage welding machine: As the so-called medium frequency inverter communication, the input part is generally three-phase input, and full bridge rectification and inversion are also carried out. Therefore, the input part is basically the same as the medium frequency inverter DC welding machine, while the output part is communication, with adjustable frequency between 40-150Hz and waveform output as square wave or sine wave. The entire process is transformed from communication to communication, with three-phase input, single-phase output, frequency adjustable, and waveform basically square wave. This is the basic principle of intermediate frequency communication, also known as intermediate frequency technology.

The four key elements of energy storage welding machine welding: When welding any workpiece, it is hoped that perfect welding points can be welded. Therefore, in order to produce such a good process, attention should be paid to four key points, namely energy, time, resistance, and material. The output of welding energy and welding time during this process depend on the setting of welding power parameters, while the key to welding resistance lies in the pressure of the welding head and the raw material being welded. The current of the welding machine, the required welding time, the welding data, and the welding pressure become the four major elements of welding.
