Product Q&A

1. Induction tempering

Tempering solutions are now mainly used in automobile manufacturing and auto parts industries. In fact, tempering can be performed on all quenched parts, including bars, joints, shafts, and so on.

What is induction tempering?

Induction tempering is a heating process that optimizes the mechanical properties of hardened workpieces, such as toughness and ductility.

What are the advantages?

Compared with the heating furnace, the main advantage of induction tempering is speed. Tempering the workpiece only takes a few minutes, sometimes even a few seconds. The heating furnace usually takes several hours. Induction tempering is fully suitable for online integrated processing, which can minimize the number of parts to be processed. Induction tempering is more conducive to quality control of each workpiece. The integrated induction tempering station also saves valuable space.

What is the use of induction tempering?

Induction tempering is now widely used in the automotive industry. It can be used on all hardened parts, such as shafts, bars and joints. At the same time, this process can also be used to temper the hardened workpiece in the pipe industry. Induction tempering is sometimes carried out in the quenching station, and sometimes in one or more independent tempering stations.

2.Induction Brazing

What is induction brazing?

Brazing is a material welding process that uses a brazing filler metal (usually also using an oxidation-resistant solvent as a flux) to weld two closely-attached metals together without melting the base material. Induction heating will melt the brazing filler metal, and the base material will then completely adsorb the brazing filler metal through capillary action.

What are the advantages?

Induction brazing can weld all kinds of metals, even ferrous and non-ferrous metals. Induction brazing is precise and fast. Only the narrow defined area is heated without affecting the adjacent areas and materials. The correct brazing joint is firm, leak-proof and corrosion-resistant. At the same time, it is extremely clean, and usually no further milling, grinding or finishing is required. Induction brazing can be ideally integrated into the production line.

What is the use of induction brazing?

Canroon brazing technology can be used for practically any brazing task. So far, our brazing technology has been widely used in the electrical industry, mainly for the brazing of components in generators and transformers, such as copper bars, conductive bars, leads, wires and short-circuit rings. At the same time, this type of technology can also be used for brazing of oil pipes and AC systems and brake components in the automotive industry. The aviation industry also applies induction brazing technology in the brazing of fan blades, casing segments, and fuel and hydraulic systems. In the home appliance industry, our brazing technology can be applied to the brazing of compressor components, heating elements and faucets.

3.Induction welding

What is induction welding?

Using induction welding, the workpiece can get heat through electromagnetic induction. The speed and precision of induction welding make it ideal for pipe edge welding. In this process, the tube passes through the induction coil at high speed. Their edges are then heated and pressed together to form a longitudinal straight weld. Induction welding is especially suitable for mass production. The induction welding machine can also be equipped with a contact welding head to convert it into a dual-purpose welding machine.

What are the advantages?

Automatic induction longitudinal straight seam welding is a reliable, high-throughput process. EFD Induction welding equipment has low power consumption and high efficiency, which can reduce costs. Its controllability and repeatability minimize the scrap rate. Our welding machine is also very flexible, and the automatic load matching function ensures full power output in various pipe sizes. Its small footprint allows it to be easily integrated or retrofitted into the production line.

What is induction welding used for?

Induction welding is applied to straight seam welded pipes in the pipe industry for stainless steel (magnetic and non-magnetic), aluminum, low carbon and high strength low alloy (HSLA) steels and a variety of other conductive materials.
