Induction heating welding is a device that uses the principle of electromagnetic induction to generate high-frequency induced eddy current thermal effects, thereby heating the workpiece. It is essentially a frequency converter with power control function.
It mainly melts the solder by heating it to a certain temperature, thereby connecting two metals of the same or different materials together. The specific applications are as follows:
a. Welding of various hardware cutting tools: welding of diamond cutting tools, grinding tools, drilling tools, alloy saw blades, hard alloy turning tools, milling cutters, cutting tools, cutting tools, woodworking drill bits, etc.
b. Welding of various hardware machine accessories: silver welding and copper welding of four types of metal or dissimilar metals, including hardware bathroom products, refrigeration copper accessories, lighting accessories, precision tool accessories, hardware handles, egg beaters, alloy pots and steel, steel and copper, and copper and copper.
c. Composite pot bottom welding is mainly used for three-layer welding of round, square, and other irregular flat stainless steel pot bottoms and aluminum sheets, and can also be used for brazing other metal surfaces.
d. The welding of the heating plate of an electric kettle is mainly used for welding between stainless steel flat bottoms, inscriptions, and various shapes of electric heating tubes.

Specification

Imagine a machine, much like a wizard from a fantasy tale, that uses an invisible force to heat and join metals. This wizard is called an ultrasonic induction heating welder. It wields the power of high-frequency electromagnetic fields to create whirlpools of electric currents within the metal pieces. Just as a spellcaster would, it rapidly changes the polarity within its magical coil, summoning a strong magnetic field that envelops the metal needing enchantment. The metal, now in the coil’s embrace, is penetrated by this magnetic force, stirring up currents within itself that flow in a vortex, opposite to the induction current.

This mystical dance within the metal generates heat due to its natural resistance, much like friction generates warmth. This heat, known as Joule heat, swiftly raises the temperature of the metal, allowing it to meld and fuse, achieving the welder’s goal.

The ultrasonic induction heating welder boasts many advantages. It’s swift, bringing the metal to the desired temperature in a blink of an eye. After the heating spell, the metal not only becomes harder on the surface but also retains a thick layer of malleability beneath, reducing stress and enhancing its resistance to fatigue and tension. This wizardly device fits perfectly into the assembly line of production, aiding in specialization and automation, easing management, cutting down transportation costs, saving manpower, and boosting productivity. It’s a champion of energy efficiency and environmental friendliness.

However, even the most powerful wizards have their limitations. The ultrasonic induction heating welder is complex and demands a high initial investment. Its flexibility is not its strong suit, especially when dealing with intricately shaped metal pieces.

In the realm of applications, this magical device finds its use in various industries such as automotive, aerospace, electronics, and healthcare. It’s versatile, capable of heating a plethora of materials including metals, plastics, ceramics, and composites. Its specific applications include hardening, tempering, welding, brazing, and annealing to relieve stress.

In summary, the ultrasonic induction heating welder is an efficient, energy-saving, and eco-friendly apparatus. Despite some constraints, it continues to hold vast potential across numerous industrial landscapes.

Specification

The principle of high-frequency induction heating welding is to use high-frequency alternating current to flow towards a conductor (usually a copper tube) that is curled into a circular shape, generating a magnetic beam. When the metal is placed inside, the magnetic beam will penetrate the metal body and generate eddy currents (rotating currents) in the direction of self rotation with the magnetic beam. This induced current generates heat under the influence of eddy currents, and this heating method is induction heating. Therefore, heated objects such as metals can be heated in a non-contact state. At this point, the characteristic of eddy current is the concentrated induction heating on the object close to the coil, which is stronger on the surface and weaker inside the object. Using this principle, the necessary areas of the heated object are centrally heated to achieve instantaneous heating effect, which relatively increases production and workload.
