Do you know high frequency welding? High-frequency welding is actually a process that uses resistance heat generated by high-frequency current through the contact surface to connect metals, Commonly known as high-frequency welding. Today we talk about high-frequency induction aluminum welding in high-frequency welding.
Definition:
Aluminum welding is to connect aluminum parts through aluminum solder.

The key point of high-frequency induction aluminum welding is the solder, and the size of the welding ring is a more difficult problem. First of all, it is necessary to ensure the size of the welding ring, and at the same time, take into account the welding qualification rate and the cost of the welding ring.

Soldering flux: In order to increase the fluidity of the solder, it is sometimes necessary to apply a flux. Including medicine skin, medicine core, self-drilling.

High-frequency induction aluminum welding is most prone to corrosion problems during use, and corrosion is also a special defect of brazing. It is caused by excessive dissolution of the base material into the solder. Excessive dissolution will increase the melting point and viscosity of the liquid solder, deteriorate the fluidity, and cause pits or perforations due to excessive dissolution of the base metal to the liquid solder.

Therefore, in the process of high-frequency induction aluminum welding, we must choose precise instruments, high-precision heating equipment, and secondly, choose special welding rings for high-frequency welding, which can avoid the appearance of corrosion to a large extent.
Today, what I recommend to you is POLARIS-ETeK's all-digital high-precision control system (specially used for aluminum welding control). What are the advantages of this system?
1. This heating system adopts DSP or ARM full digital control technology to ensure stable and accurate power output. The heating time can be accurate to 0.1S and the heating current is accurate to 1A.

2. It has a rich communication interface, which can be connected to industrial buses such as RS-485, Profibus, CAN, etc., to realize automatic control and remote monitoring of equipment;
3. Support the storage of heating parameters, which can be recalled with one key on the computer and other equipment;
So many people choose to use induction welding, but the country now pays more attention to environmental protection. Will it stop using it in a few years? Compared with other brazing modes, who is more environmentally friendly?
The answer is self-evident, induction welding is definitely more environmentally friendly, for the following two reasons:
1) Power supply environmental protection
2) In ordinary soldering, due to the use of flux flux, the flux will volatilize, and there will be residues, which need to be cleaned, which leads to environmental problems.
However, if vacuum brazing is used, no flux is needed, and there is no environmental protection problem.
In general, induction brazing is very environmentally friendly, and is conducive to automation, with low welding cost and high speed, which is very suitable for non-cremation welding.
Summarize
Induction brazing technology is not only widely used in the brazing of large machinery, but also can complete the welding of various high-precision and complex parts. The induction brazing technology has high efficiency and wide applicability to the base metal to be connected.
At present, POLARIS-ETeK's equipment has passed IOS9001 certification and CE certification, etc., and has more than 20 industry patents. Finally, I hope that "POLARIS-ETeK" services and products can contribute to the development of your business.
