Frequency selection

Power selection

Brazing

Drills,turning tools, reamers, milling cutters, drills, etc. and composite welding of different materials on the bottom of stainless steel pots.

The larger the welding volume, the lower the frequency should be. For tools with a volume smaller than 30*30*30, high frequency can be used; if it is larger than 30*30*30, medium frequency can be used. Principle: The larger the diameter of the workpiece, the lower the bridging rate should be.

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

Diathermy

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)

Select the appropriate power according to the production efficiency. The higher the power, the faster the speed. For details, please consult the company's technical personnel

Quenching

Shafts, gears, sprockets, machine tool guide rail accessories quenching, 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 ;

Intermediate frequency 1-20KHZ above 2.5mm .

Combined with the shape of the workpiece, quenching method, quenching hardness, hardened layer requirements and materials, etc., you can consult the company's technical personnel for details.

Annealing

Metal wire and pipe annealing, hydraulic fittings, auto fittings, knife scissors, stainless steel pot annealing, etc.

Combined with the comprehensive consideration of workpiece annealing requirements, annealing speed and materials, please consult the company's technical personnel for details.

Smelting

Gold, silver, copper, lead and other precious metals

Intermediate frequency; optional high frequency for small capacity

Depends on 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.

Depends on the specific situation

Depends on production speed, material, temperature

Special features

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