Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched. The heat source is on the surface of the workpiece, the heating speed is fast, and the thermal efficiency is high.

Induction brazing is the process of joining two or more metals using induction heating. Induction heating utilizes the electromagnetic field to provide heat without contact or flame. Induction brazing is more localized, repeatable, and easier to automate compared to traditional torch brazing.

Induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. The advantage of the induction furnace is a clean, energy-efficient and well-controlled melting process, compared to most other means of metal melting.

Annealing is a heat treatment process that changes the physical and sometimes also the chemical properties of a material to increase ductility and reduce the hardness to make it more workable.

Gas oil fired melting furnace and casting system. Burner use gas oil for heating, Can melt aluminum, copper, zinc, lead and so on.

Hardening is the process by which something becomes harder or is made harder. Hardening (metallurgy), a process used to increase the hardness of a metal.

Post weld heat treatment (PWHT) is a controlled process in which a material that has been welded is reheated to a temperature below its lower critical transformation temperature, and then it is held at that temperature for a specified amount of time.
