DSP Digit Control Induction Welding Equipment For Heating Tube and Pot Bottom

WHAT IS INDUCTION WELDING:

Welding is the process of joining two metals where the base material is elevated to a high temperature to exceed its melting point and in which, using its liquid state, are mixed to form a union of the fusion of all parties involved including a filler material if exists.

Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece. The welding apparatus contains an induction coil that is energised with a radio-frequency electric current. This generates a high-frequency electromagnetic field that acts on either an electrically conductive or a ferromagnetic workpiece. In an electrically conductive workpiece, the main heating effect is resistive heating, which is due to induced currents called eddy currents. In a ferromagnetic workpiece, the heating is caused mainly by hysteresis, as the electromagnetic field repeatedly distorts the magnetic domains of the ferromagnetic material. In practice, most materials undergo a combination of these two effects.

TECHNICAL PARAMETERS OF THE INDUCTION WELDING MACHINE:

APPLICATIONS OF THE INDUCTION WELDING MACHINE:

It uses the high power IGBT high frequency equipment to provide heating power and the pneumatic system as the drive. It has such features as stable operation, precise control, easy operation an high rate of products meeting standards, which is the most ideal equipment for manufacturing on new generation of electric heating stainless steel kitchen utensil.

It is applicable to the welding of such electric heating products as electric heating pan, hot-water kettle, frying pan and coffee pot, which can make the stainless steel plate, alumium sheet and tubular electric heating element of different shapes and thickness form an integral part through one-off metal braze welding.

THE ADVANTAGES OF THE INDUCTION WELDING:

• Energy saving
• No physical contact and less maintenance.
• Minimizes the time of heating. Therefore it reduce oxidation and decrease production time.
• Easier cleaning processes afterwards
• Reduces the heat affected area
• Reduced risk causing a more pleasant work environment than conventional methods.
• Possibility to automate welding processes which leads to an easier implementing and repetitive process.
