What is induction post-heating?
-
Induction post heating is the process of applying controlled heat to a metal component after a primary operation such as welding, coating, forming, or hardening. The purpose is to relieve residual stress, improve metallurgical properties, or assist in curing coatings or adhesives.
Induction post heating uses an induction coil to generate heat directly within the workpiece through electromagnetic induction. This method ensures precise, uniform, and repeatable heating over targeted areas—without direct contact or open flames.
In welding applications, induction post heating is often used for post-weld heat treatment (PWHT), especially on thick-walled steel pipes or high-stress joints in industries like oil & gas, shipbuilding, and power generation. The process helps prevent cracking, improve ductility, and restore the desired microstructure of the metal.
At LJINDUCTION, we design custom induction post heating systems that meet the exact time-temperature requirements of your application. Whether it’s spot heating after welding or broader surface heating for coating processes, our systems offer consistent, energy-efficient performance.
Benefits of Induction Post Heating
-
Induction post heating offers numerous advantages over conventional methods like resistance heating or furnace-based solutions, especially in terms of control, efficiency, and safety.
Induction post heating provides precise temperature control with rapid heat-up and cool-down rates. This minimizes thermal distortion and allows for accurate thermal cycles that match engineering specifications.
LJINDUCTION’s induction systems are ideal for localized heating, helping you treat only the required zones—saving time, energy, and resources. This is particularly valuable in field operations or on large components that cannot be moved easily.
Induction post heating improves process consistency by eliminating human variability and ensuring repeatable results across production batches. Digital controllers and data logging help ensure compliance with welding codes and quality standards.
The flameless nature of induction post heating also enhances workplace safety. There are no hot surfaces or open flames, and the equipment can be operated in confined or hazardous areas with lower risk.
Additionally, induction systems are clean, quiet, and require minimal maintenance. They can be mounted on portable carts, robots, or gantry systems—making them flexible for both workshop and on-site use.
With LJINDUCTION’s expertise in customized heating solutions, you gain access to reliable induction post heating equipment that integrates seamlessly into your workflow, whether you're doing field PWHT, curing structural adhesives, or re-tempering hardened surfaces.
