The invention relates to the field of production equipment of refrigerating system pipelines and particularly belongs to high-frequency heating and welding equipment. The high-frequency heating and welding equipment comprises a rack, a high-frequency heating soldering mechanism, a guiding mechanism, a cooling mechanism and a material transferring mechanism, wherein the high-frequency heating soldering mechanism comprises a high-frequency controller, an induction coil, a solder tray, a first motor and a second motor; the guiding mechanism comprises a first cylinder and a second cylinder which are separately arranged at the two sides of the induction coil, the first cylinder is connected with a first guide wheel, and the second cylinder is connected with a second guide wheel; the cooling mechanism is formed by connecting a cooling water pipe with a sprayer; and the material transferring mechanism comprises a material transferring plate and a third cylinder. By adopting the high-frequency heating and welding mechanism, the automatic non-flame heating of copper pipes in the induction coil is realized, solder wires can be automatically fed through feeding gears which are meshed with each other, and the two copper pipes which pass are clamped through the guiding mechanism and the material transferring mechanism. Automatic wire feeding and welding are realized, the production efficiency is high, and the quality is stable and reliable.
