Aluminum Welder
Aluminum welding machine: Aluminum welding machine, in fact, is to melt aluminum and aluminum alloy materials by heating or pressure to achieve the effect of bonding. In the fusion process, welding wire or metal filling can be used, or two workpieces can be self-fused. Process equipment that allows the molecules at the fusion of two workpieces to penetrate each other to form a permanent connection.
Overview
Aluminum welding machine: Aluminum welding machine, which actually melts aluminum and aluminum alloy materials by heating or pressure to achieve bonding In the fusion process, welding wire or metal filling can be used, or two workpieces can be self-fused, so that the molecules at the fusion point of the two workpieces penetrate each other to form a permanent connection.
In our daily life and industry, the aluminum welding machine often referred to is generally argon arc aluminum welding machine. (MIG gas shielded welding), and the use of tungsten argon arc welding must use AC argon arc welding to weld aluminum and aluminum alloys.
Characteristics of aluminum welding machine
The aluminum welding machine uses low-voltage and high-current electric energy, converts the electric energy into heat energy instantly through the arc, and uses high-purity argon gas. As a shielding gas during welding, it can avoid pores and impurities during welding. At the same time, AC argon arc welding and MIG welding have a certain cathode cleaning function, which can directly remove the oxide film on aluminum and aluminum alloys. Because the aluminum welding machine is small in size, simple in operation, convenient in use, high in welding efficiency, good in welding seam formation and large in penetration depth, it can penetrate through aluminum and aluminum alloy plates to achieve high-quality bonding effect, and the welding strength is the same as that of the base metal. Therefore, it can be widely used in various fields of industry and life.
Arc light will be generated in the process of using the aluminum welding machine. The arc light contains infrared rays and ultraviolet rays, and also produces harmful substances such as metal vapor and soot. The tungsten rod in argon tungsten arc welding contains a small amount of radioactive elements. Therefore, sufficient protective measures must be taken. In addition, due to the use of argon as the protective gas, it is not suitable to operate in a windy welding field.
Development trend of aluminum welding machine in China
High efficiency and energy saving
Aluminum welding is slowly made by traditional flame brazing before Switching to AC argon arc aluminum welding machine, the welding efficiency and level are a qualitative leap, and the use of pulsed MIG gas shielded welding, the welding efficiency is three times that of manual AC argon arc welding, and it will also save metal filler materials and welding. Auxiliary processes such as preheating for medium and thick aluminum plates can save 30%-50% of welding costs. It can be seen that in the future, a large number of pulse MIG gas shielded aluminum welding machines will be used to replace the AC argon arc aluminum welding machines that currently occupy a certain share.
High-quality, high-difficulty welding effect
The pulse MIG gas shielded aluminum welding machine can meet the industrial welding of medium and thick plates. However, for the welding of aluminum sheets with a thickness of less than 0.8mm, the pulse MIG welding technology is still quite lacking. At present, only Fronius aluminum welding machines can be welded in the world. Therefore, it is imperative to break this technical bottleneck.
Digital automatic welding
With the development of industrial technology, digital welding machines such as single-chip microcomputer, DSP, FPGA, etc. have matured one after another. Through point-to-point and bus structure, special welding machines or arc welding robots can be realized. Automatic welding has also been used in production, which can replace the difficult and high-strength automatic welding operations that cannot be completed by humans. At the same time, the digital aluminum welding machine supports network remote monitoring and fault diagnosis; the automation of aluminum welding machines will also be achieved in recent years. Widespread promotion and application.
