Induction heating is the process of heating an electrically conducting object (usually ferrous and nonferrous metal alloys) by electromagnetic induction.
induction heating service,induction heater,induction heating equipment and induction heating system are supplied by DaWei Induction Heating Machine Co.,Ltd
Induction heating is a form of non-contact heating for conductive materials, when alternating current flows in the induced coil, varying electromagnetic field is set up around the coil, circulating current(induced, current, eddy current) is generated in the workpiece(conductive material), heat is produced as the eddy current flows against the resitivity of the material.
Induction heating is a rapid ,clean, non-polluting heating form which can be used to heat metals or change the conductive material’s properties. The coil itself does not get hot and the heating effect is under controlled. The solid state transistor technology has made induction heating much easier,cost-effective heating for applications including soldering and induction brazing ,induction heat treating, induction melting,induction forging etc.<
Induction Brazing is a materials-joining process that uses a filler metal to join two pieces of close-fitting metal together without melting the base materials.
Induction hardening treatment is widely used for surface hardening steels,Carbon steels,Alloy steels,Stainless steels,Cast iron,Copper,etc.
Many videos are display about brazing,melting,induction hardening,hot forging, preheating,annealing,heating treatment and shrink fitting,etc.
Ultra high, medium and high frequency solid state induction power supplies for melting brazing,hardening,forging and heating conductor material.
Induction melting is a process where metal is melted into liquid form in an induction furnace's crucible.The molten metal is then poured into a cast.
Induction bonding solutions are mainly found in the automotive industry, for example for bonding of door, hood and trunk panels,rails, shelves and panels.
Induction annealing and normalizing is widely used in the tube and pipe industry and annealing wire, knife blades,steel string and copper tubing.

How does Induction Heating work ?
A source of high frequency electricity is used to drive a large alternating current through a induction coil. This induction heating coil is known as the work coil. See the picture opposite.
The passage of current through this induction heating coil generates a very intense and rapidly changing magnetic field in the space within the work coil. The workpiece to be heated is placed within this intense alternating magnetic field.
Depending on the nature of the workpiece material, a number of things happen...
The alternating magnetic field induces a current flow in the conductive workpiece. The arrangement of the work coil and the workpiece can be thought of as an electrical transformer. The work coil is like the primary where electrical energy is fed in, and the workpiece is like a single turn secondary that is short-circuited. This causes tremendous currents to flow through the workpiece. These are known as eddy currents.
In addition to this, the high frequency used in Induction Heating applications gives rise to a phenomenon called skin effect. This skin effect forces the alternating current to flow in a thin layer towards the surface of the workpiece. The skin effect increases the effective resistance of the metal to the passage of the large current. Therefore it greatly increases the induction heating effect of the induction heater caused by the current induced in the workpiece.
