Induction Heat Treatment
At LD, we specialise in advanced induction heating techniques that offer fast, efficient, and highly controllable heat treatment solutions for a wide range of industrial applications. Induction heating uses electromagnetic fields to generate heat directly within metal components, providing precise temperature control and rapid heating without direct contact or open flames.
How Induction Heating Works
Induction heating relies on electromagnetic induction to produce heat inside conductive materials. When an alternating current passes through an induction coil, it generates a magnetic field that induces electric currents (eddy currents) within the metal part. These currents generate heat internally due to the metal’s resistance, allowing rapid and uniform heating exactly where it’s needed.
Equipment and Capabilities
Our induction heating equipment is built for portability and flexibility, making it suitable for a wide range of site conditions. We use modern power units, including the Miller ProHeat 35, allowing us to match the output to each job depending on size and complexity.
We operate both air-cooled and liquid-cooled systems, giving us the flexibility to work efficiently across different environments and duty cycles.
Key features:
-
Rapid heating for efficient on-site operations
-
Precise temperature control with digital monitoring
-
A range of coil designs to suit different component shapes and sizes
-
Suitable for pre-heating, shrink fitting, stress relieving, and more
This setup allows us to work quickly and accurately, whether it’s a small component or a larger, more demanding project.
Key Applications
Our Induction heating services are widely used for:
-
Pre-heating metals before welding or fabrication to prevent cracking and distortion.
-
Post-Weld Heat Treatment (PWHT) to relieve residual stresses and enhance material strength.
-
Shrink Fitting (Expansion Work), where controlled heating expands components for assembly or removal.
-
Stress Relieving and Annealing, which soften metals to reduce brittleness and improve durability.
-
Surface Preparation for coatings or bonding, ensuring uniform heat distribution.
-
Rolling Induction
Rolling Induction Heating
When pipes or vessels are placed on rollers, our induction rolling machine provides an excellent solution for continuous welding processes. This equipment allows the component to rotate steadily while heat is applied uniformly through electromagnetic induction, maintaining consistent temperature along the weld area. The induction rolling machine ensures precise and efficient heating, reducing thermal distortion and enhancing weld integrity for long seams on cylindrical or tubular parts. This method supports smooth, uninterrupted welding operations, improving both quality and productivity on site
