Advantages of high frequency welding machine for welding finned tube
High frequency welding machine welding uses the skin effect and proximity effect unique to high frequency current, so that the welding current is concentrated on the surface layer of the contact, the temperature of the surface joint surface rises quickly, and the surface to be welded is heated to a molten or near molten plastic state , And then quickly extruded into a joint welding method.
This welding method has a series of advantages: the heat-affected zone of the weld is small, and the heating speed is fast, which can greatly improve the welding speed and weld quality of the frequency welding machine, and can use strip steel without pickling, shot peening and trimming as a blank At the same time, it can weld alloy steel, high alloy steel and non-ferrous metal pipes, greatly reducing the unit power consumption. A set of welding equipment can be used to produce various metal welded pipes. For different metals, it is only necessary to change the welding power and welding speed accordingly.
Welding speeds of up to 100-120 m / min. Such high welding speeds and beveled molten metal layers allow welding of light alloy, stainless steel, copper, brass, zirconium and other metal pipes without protection.
