Induced current by the welding was heated to a temperature to melt the solder, so that the two different materials of the same metal material or wetted stick together after the induction heating equipment.
Frequency
Brazing Machine high frequency power selection
When welding the cross-sectional area less than 30 * 30mm, the frequency is generally used in high frequency induction welding equipment 60 ~ 80KHz, when the number of welding the cross-sectional area greater than 30 * 30mm, and processing more, you can choose the frequency between 15 ~ 60KHZ, power slightly larger Super Audio induction heating equipment. Because of different cross-sectional size of the brazing, the choice of frequency bands, power is also different.
Brazing high-frequency brazing machine: the surface with a flux (generally used borax) cleaning snapping together a good piece, the solder joints on or near the gap between the gap junction. When the workpiece and the solder is heated to a temperature slightly above the melting point of the solder, the solder melts (work not melt), and by means of capillary action is drawn and filled the gap between the solid piece, mutual diffusion liquid solder with the workpiece metal dissolution After stopping heating, the workpiece into the lime or sand heat insulation (simple weld tempering) after a period of time, remove that formed brazed joints.
Welding of heating: heating methods are mainly iron heating, flame heating, resistance heating, induction heating, soaking furnace heating and heating.
Brazing method: commonly used process for many, mainly by the use of equipment and works of distinction. Such as by heat differentiate, there are infrared, electron beam, laser, plasma, glow discharge brazing; work process divided by the contact reaction brazing and diffusion brazing. Contact reaction brazing using solder and base metal reaction liquid filling joint gap. Diffusion brazing is to increase the heat diffusion time, the weld and base metal full uniform, to obtain the same performance as the base material of the joint. Almost all of the heating source can be used as soldering heat, and so the brazing classification.
High frequency brazing machine as a new welding method is its significant advantages:
1. Energy saving
2. High welding efficiency
3. High welding quality: welding surface smooth, consistent welding quality, improve the overall quality of welding products
4. Simple and easy to operate, a few seconds to learn
5. welding low cost, which is about 1/4 or so conventional oxidation welding.
