Description

Inverter digital welding machine

Technical field

The utility model relates to the field of welding equipment, in particular to an inverter digital welding machine.

Background technique

Welding: Also known as welding or splicing, it is a manufacturing process and technique for joining metals or other thermoplastic materials such as plastics in a heated, high temperature or high pressure manner. Welding is achieved by the following three ways:

1. Fusion welding—heating the workpiece to be joined to partially melt it to form a molten pool. After the molten pool is cooled and solidified, it is joined, and if necessary, it can be added with the aid of the filler;

2, pressure welding - the welding process must apply pressure to the weldment;

3. Brazing - A metal material with a lower melting point than the base material is used as the brazing material, and the base material is wetted by the liquid brazing material, the gap is filled, and the base material is mutually diffused to realize the link weldment.

The welding machine is an electric appliance that supplies certain characteristics to the welding. The welding is flexible, simple, convenient, firm and reliable. The advantages of welding and even the same strength as the base metal are widely used in various industrial fields, such as aerospace, ships, automobiles, containers and the like.

The electric welder is actually a transformer with reduced external characteristics, which converts 220V and 380V AC into low-voltage DC. The welder can be divided into two types according to the type of output power, one is AC power; the other is DC. The DC welding machine can be said to be also a high-power rectifier, which is divided into positive and negative poles. When the AC input is made, after being transformed by the transformer, it is rectified by the rectifier, and then the power supply with the falling external characteristic is output, and the output terminal is turned on and off. When there is a huge voltage change, the two poles ignite the arc in the event of an instantaneous short circuit, and use the generated arc to melt the electrode and the welding material, and then cool them to achieve the purpose of combining them. The welding transformer has its own characteristics, and the external characteristic is the characteristic that the voltage drops sharply after the welding rod is ignited.

Inverter digital welders are extremely versatile. Assembly of the mainframe includes assembly of structural components and assembly of inverter circuits. Assembly of structural components includes assembly of plastic panels and assembly of sheet metal parts. The traditional inverter digital welder's transshipment capability and the heat dissipation capacity required for normal operation limit its use time and affect the efficiency of equipment use.
