35KW Medium Frequency Induction Welding Equipment

Welding equipment is a welding method that uses high-frequency, intermediate-frequency or power-frequency induction current as a heat source. High frequency heating is suitable for welding thin-walled pipe fittings. The use of welding equipment coaxial cables and split-combination induction coils can be brazed on site far away from the power source, and is especially suitable for welding of certain large components, such as pipe joints that need to be disassembled on rockets. It is also often used in pin soldering in the electronics industry. Welding equipment is used to heat the solder joints in the area at the same time, and the tin wire is sent to the solder joints through the tin feeding mechanism to complete the soldering.

During induction brazing, the brazed part of the part is placed in an alternating magnetic field, and the heating of this part of the base material is realized by the resistance heat of the induced current generated in the alternating magnetic field. The higher the frequency, the smaller the depth of current penetration. Although the surface layer is heated quickly, the thickness of the heating is thinner. The interior of the part can only be heated by the heat conduction from the surface layer to the interior. Welding equipment is the so-called skin effect. Induction coil is an important part of induction welding equipment. The basic principle of correct design and selection of induction coils is to ensure rapid, uniform heating and high efficiency in the welding year. Generally, the welding equipment induction coil is made of pure copper tube, and the tube is cooled by water during operation. The thickness of the tube wall should be less than the current penetration depth, generally 1~1.5mm. It can be seen that welding equipment is not advantageous to select an AC frequency that is too high.

Generally, a frequency around 500kHz is more appropriate. In addition, the skin effect is also related to the resistivity and permeability of the material. The larger the resistivity, the smaller the permeability, and the weaker the skin effect. On the contrary, the skin effect is more pronounced.

What are the welding steps?

Assuming you glued everything together correctly, you can now go back and fill the remaining seams with welds. This is where you really need to hone your welding skills, so pay close attention to how the welding torch angle, travel speed, and electrical viscosity affect the appearance of the welding.

The most important thing to consider when performing these welds is to maintain the consistency of the above categories. In other words, once you have determined the correct torch angle, do not change it midway through welding. Your travel speed should be quite fast, and you don’t want to speed up or slow down during the welding process, but to maintain a constant speed. Finally, your electrical extension should not exceed 1/2 inch or less than 1/4 inch, so it is best to keep it around 3/8 inch.

Mastering the consistency of the welding technique is the key to being able to weld proficiently. Some practice is required before the weld looks perfect. If the effect is not good on the first try, please keep this in mind, and please be patient to remind yourself that the exercise is perfect.

What is high frequency induction welding?

High-frequency induction welding is used to make the strip into a tube or tube, and then feed it into a roller, which makes the strip into a cylindrical shape. The overlapping edges converge between the squeeze rolls to create a V-shape at the welding point. The included angle of steel is usually 2-5°.

The high frequency coil introduces current into the tube before the squeeze roller. The current is concentrated on the edge of the V-belt, and the resistance heats a narrow area of ​​the edge to the welding temperature. The squeeze roller consolidates the weld by expelling any molten material and contaminants, and forming small up-forged beads on the inside and outside of the pipe. These beads can be scraped off the tube immediately to provide a smooth surface.

Will induction heating increase my utility bills?

Not likely. Induction heating is a very effective, efficient means of heating. Most of our customers who are switching to induction for the first time see their utility bills go down.
