35KW High Frequency Induction Welding Machine
What are 35KW High-Frequency Induction Welding Machine Advantages?
KEXIN high-frequency induction heater for welding machines has fast heating speed and high production efficiency. The unit power of high-frequency induction brazing machine heating is as high as 500-1000/kW2, so the heating speed is extremely fast, and the time required for large-area welding is only a few seconds, which can greatly shorten the welding time, increasing productivity, and reduce Cost of production. The heat-affected zone is small and the damage to the substrate is small.
The skin effect of high-frequency induction welding equipment makes the heating depth of the workpiece to be welded very shallowly, even up to a few tenths of a millimeter. It only relies on the heat transfer of the workpiece to conduct heat to the core. When any point of the workpiece enters the inductor, it is heated sharply to melt When the temperature leaves the sensor, it enters a state of rapid cooling. There is almost no holding time and the heating time is extremely short, so the heat-affected zone is very small and basically does not damage the substrate. In addition, the formation of scale is very small, and even if heated in air, the surface of the blank is oxidized and decarburized very little.
Avoid or reduce the formation of brittle compounds at the interface, and the welded joint has excellent mechanical properties. Due to the fast induction heating speed, concentrated energy, short cooling time, and fine austenite grains obtained, the induction-heated workpiece has a very good metallographic structure. For dissimilar metal welding, the extremely short heating time can reduce the formation of brittle compounds at the interface and can effectively improve the mechanical properties of the welded joint.
It can realize the welding of complex interfaces. The heating head of the inductor can be designed into the corresponding shape according to the heating needs of different workpieces, and the extremely short heating time can achieve local heating, the temperature of the heating zone is established quickly, and the temperature transition zone is narrow so that the sensor can move along the complex interface. Realize the welding of complex interfaces. In addition, high-frequency induction heater welding machine also has the advantages of energy saving, reproducibility, and easy automated production. induction welding copper; induction welder for sale; induction preheating welding

35KW High-Frequency Induction Heater for Welding Machine
It is an induction welding equipment that uses induction current to heat the solder to a certain temperature to melt the solder so that two metals of the same material or different materials are wetted and bonded together.
When the high-frequency induction welding machine’s cross-sectional area is less than 30*30mm, a high-frequency induction heater for welding machine with a frequency of 60~80KHz is generally used. When the welding cross-sectional area is greater than 30*30mm and the number of processing is large, the frequency can be selected between 15~60KHZ. Super audio frequency induction welding machine with slightly larger power. Because the size of the brazing section is different, the selected frequency band and power are also different.
The welding process of the high-frequency induction welding machine: the surface is cleaned with flux to close the workpiece together, and the brazing filler metal is placed near the joint gap or between the joint gaps. When the workpiece and the solder are heated to a temperature slightly higher than the melting point of the solder, the solder melts and is sucked into and fills the gap between the solid workpiece by capillary action. The liquid solder and the workpiece metal diffuse and dissolve with each other. After the heating is stopped, Put the workpiece in quicklime or heat preservation sand for a period of time, and then take it out to form a brazed joint. induction heater from welder; induction welding copper; induction welder for sale; induction preheating welding

What are the welding processes of high-frequency induction welding machines?
According to different classifications, the welding process of high-frequency induction welding machines is divided into the following types:
According to the type of equipment, it can be divided into: fixed high-frequency brazing process and portable high-frequency brazing process;
According to the different welding temperatures, it can be divided into: high-frequency brazing and high-frequency soft soldering;
According to different operation modes, it can be divided into automatic high-frequency welding, semi-automatic high-frequency induction welding machine, and fully automatic high-frequency welding.
What are the characteristics of high-frequency induction welding？
(1) High-frequency induction welding machine has the characteristics of fast heating speed, concentrated heat, and easy-to-realize automation. Its skin effect makes the heat-affected zone small and damages the substrate.
(2) Dissimilar metal connection composites are used more and more widely, but due to the huge difference in physical and chemical properties, their fusion brazing is difficult. The unique characteristics of a high-frequency induction heater for welding machines can realize the brazing and cladding welding of dissimilar metals, and the joints form a metallurgical bond. , High welding quality.
(3) Adopt appropriate welding processes, reasonably control brazing temperature and time, and use high-frequency induction welding machine heating to realize direct melting and brazing of dissimilar metals.
(4) The flux has the function of dissolving the oxide film on the surface of the base material to be welded, preventing the re-oxidation of the base material being welded, reducing the surface tension of the molten solder, and protecting the surface of the welding base material.
(5) Induction cladding has the characteristics of fast heating speed, short production cycle, and controllable thickness of the cladding layer.
How does an induction welder work?
An induction welder uses induction heating from radio frequency alternating current to magnetically excite an implant placed at the joint interface of the two parts being welded. This implant, or gasket, is normally a composite of the polymer to be welded with either metal fibers or ferromagnetic particles. induction heater from welder; induction welding copper; induction welder for sale; induction preheating welding
Heat Treatment (surface hardening, quenching, annealing, tempering).
The high frequency brazing welding machine is different from other welding machine in that its function and purpose are not just for single welding. High-frequency welding machine can be used not only for welding various metal materials, but also for processes such as heat penetration, smelting, and heat treatment. Welding is just one of its many uses.
High frequency induction brazing machines can be used for melting alloy tools, such as alloy turning tools, milling cutters, planers, saw blades, reamers, boring cutters, etc.
