AC Touch Welding Machine Pneumatic Row Welding Machine
AC resistance spot welder principle is based on the current heating the metal contact surface to make it melt-connected. Its advantages include low cost, high efficiency, high thermal efficiency, and good welding quality. It is widely used in the field of metal processing to achieve efficient and energy-saving welding effects.
Description
Feature
The principle of AC resistance spot welding machine is to generate heat on the metal contact surface through electric current, causing it to melt and combine together. The equipment usually consists of transformers, capacitors, rectifiers, spot welding tongs and control systems. The current passes through the transformer to reduce the voltage and increase the current intensity, thereby generating a large amount of heat energy. During the heating process, the metal surface is in a liquid state and forms a uniform solder joint to realize the connection of two or more metal parts.
The advantages of AC resistance spot welding machine are mainly reflected in the following aspects:
Low production cost: the welding process does not require additional consumables, reducing production costs.
High welding efficiency: fast heating speed, short welding time and rapid forming.
High thermal efficiency: the use of the workpiece itself internal resistance heat source, less heat loss, energy saving.
Good welding quality: the weld is dense to avoid defects caused by thermal influence. The nugget is surrounded by a transparent plastic ring when it is formed. The metallurgical process is simple and the welding effect is good.
