Scope of application

Frequency selection

Power selection

Brazing

Composite welding of different materials such as drills, turning tools, reamers, milling cutters, drills, etc. and the bottom of the stainless steel pot.

 Principle: The larger the welding volume, the lower the frequency should be. For tools with a volume less than 30*30*30, high can be used; for tools greater than 30*30*30, intermediate frequency can be used. Principle: The larger the diameter of the workpiece, the lower the frequency should be. 

It depends on the specific workpiece shape, material, solder, etc.

heating

Fastening and hot rolling of fasteners, standard parts, auto parts, hardware tools, copper rods, twist drills, etc.

Above Φ20, intermediate frequency (1-20KHZ)

Φ5-20, high frequency (20-100KHZ)

Below Φ5, UHF (100-500KHZ)

Choose the right power according to the production efficiency, the greater the power, the faster the speed. For details, please consult the company's technical staff.

Quenching

Quenching of shafts, gears, sprockets, machine tool guide parts, etc.

Principle: The shallower the hardened layer is required for the workpiece, the higher the frequency should be.
Ultra high 100-500KHZ below 1mm

1-2.5mm super audio 20-100KHZ

IF 1-20KHZ above 2.5mm;

Consider the shape of the workpiece, the quenching method, the quenching hardness, the requirements of the hardened layer, and the material. For details, please consult the company's technical staff.

annealing

Metal wire and pipe annealing, hydraulic fittings, auto parts, knife and cutting pliers, stainless steel pot annealing, etc.

Consider the requirements of annealing of the workpiece, annealing speed and materials, etc., please consult the company’s technical staff for details

Smelt

Precious metals such as gold, silver, copper, lead, etc.

Intermediate frequency; small capacity optional high frequency

It depends on the furnace and production efficiency.

welding

Heating coating of aluminum-plastic pipes, steel-plastic pipes, cables and wires; aluminum foil sealing used in food, beverage, and pharmaceutical industries.

According to the specific situation

It depends on the production speed, material and temperature.

Special functions and supporting equipment

Such as dual-frequency equipment, multi-load matching type (double heads, multi-tap), automatic control type, one to two, bridge oil pipeline elbow, constant power and constant current, flexible connection sensor.
