銅管の高周波溶接の原理

銅管の高周波溶接の原理は、銅管と溶接材料の間に流れる高周波電流によって発生する熱を利用して溶接材料を加熱し、溶融することです。, それにより溶接の目的を達成します. 具体的な原則は次のとおりです:

1. 高周波電流の発生: convert low-frequency alternating current into high-frequency current through a transformer. High-frequency currents typically range in frequency from a few kilohertz to tens of megahertz.

2. Induction heating: high-frequency current passes through the cooling coil to generate an electromagnetic field. When the copper pipe enters the electromagnetic field, eddy currents will be generated by electromagnetic induction.

3. Eddy current heating: Eddy current will generate a large amount of heat inside the copper tube, causing the copper tube to heat up.

4. Melting of welding materials: During the heating process, the welding materials will also be heated and melted. The welding material is usually auxiliary welding rods at both ends of the copper pipe.

5. 溶接: When the copper pipe and the welding material have reached a molten state, the welding material will be completely fused with the copper pipe to form a strong weld.

High-frequency welding copper pipes are fast and efficient, and are suitable for production occasions that require high welding speeds, such as pipeline manufacturing, HVAC industry, 等.
