Induction Welding

WHAT IS INDUCTION WELDING?

Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece. It can be used for long production runs and is a highly automated process, usually used for welding the seams of pipes. It can be a very fast process, as a lot of power can be transferred to a localized area, so the faying surfaces melt very quickly and can be pressed together to form a continuous rolling weld.

When induction welding takes place, the work pieces heat up to under the melting temperature and the edges of the pieces are placed together impurities get forced out to give a solid forge weld.

Induction welding is used for joining a multitude of thermoplastics and thermosetting matrix composites. The apparatus used for induction welding processes includes a radio frequency power generator, a heating station, the work piece material, and a cooling system.

THE INDUCTION
WELDING PROCESS

Induction welding is a welding process that uses electromagnetic induction to heat and bond materials. During this process, a high-frequency current is passed through a coil, creating an electromagnetic field. The materials to be welded are placed within this field, where they rapidly heat up due to electromagnetic induction.

As the materials heat up, they soften and eventually melt, allowing them to bond together. Pressure can be applied to the welded materials to ensure a strong weld joint. Induction welding is often used to join metals, especially in applications that require a high level of precision and control. It is often used to manufacture pipes, tubing, and other metal parts.

Induction Welding VS. Gas Welding

1. Heating source

Gas welding usually relies on raw materials such as oxygen and acetylene to complete the welding work.
Induction welding requires only three-phase power.

2. Heating effect

Induction welding uses heating coils as the medium, and converts electrical energy into heat energy through a closed magnetic field, making the solder melt more fully, and the welding effect is more uniform and firm.
Gas welding relies more on professional welding techniques and rich welding experience to obtain higher-quality welding results.

3. Eco– friendly

Induction welding equipment consumes less energy, does not involve gas combustion, produces no smoke and waste, and is more environmentally friendly than gas welding.

4. Operability

Induction heating is not affected by manual operation, and the heating temperature, time, and other heating requirements can be customized, making it easier to realize automated production.
Gas welding is more dependent on the experience of the operator, and it is impossible to accurately set various parameters.

5. Cost

The initial investment in gas welding is smaller, which is more cost-effective for the demand of small production.
If it is for large-scale factory production, induction welding is a better choice to obtain high-quality batch products.
