Overview of Induction Preheating Equipment for Weld Seam Welding

The pre weld induction preheating equipment is mainly used to heat the welded parts locally or as a whole before welding, in order to reduce the cooling rate of the welded joint, avoid the formation of hardened structure, reduce welding stress and deformation, and prevent the occurrence of welding cracks. Induction preheating has the advantages of energy saving, fast heating speed, and high degree of automation compared to traditional flame heating, resistance heating, and other methods.

Working principle and advantages of induction preheating equipment

Induction preheating equipment is based on the principle of electromagnetic induction heating, which generates a changing magnetic field in the induction coil through alternating current, causing Joule heating of the conductive material inside the workpiece, thereby achieving the heating purpose. This method allows for direct heating without the need for intermediaries, resulting in high thermal efficiency, fast heating speed, and uniform heating process, enabling precise temperature control.

Significant energy-saving effect

The induction preheating equipment for welding seams adopts an air-cooled heating system, which does not require the installation of an induction cooling system. The energy utilization rate of induction heating is 40% -70% higher than traditional heating methods, and it has a significant energy-saving effect.

Fast heating speed

Under the same working conditions, induction heating is faster than traditional heating methods, especially suitable for scenarios that require rapid heating.

High degree of automation

Induction heating can perform real-time and accurate automatic temperature control based on the current temperature state of the heated workpiece, and adjust the power output through a temperature closed-loop control system.

environment protection

Induction heating does not produce exhaust gas or smoke, has low external heat radiation, low noise, and belongs to a green and environmentally friendly heating method.

High security

Induction heating does not produce open flames, avoiding the occurrence of dangerous events such as fires and explosions, and improving safety.

Easy to use

The induction heating device is easy to operate, can be started and turned off at any time, and has strong adaptability.

Small footprint

Induction heating equipment has a compact structure, small footprint, and saves space and infrastructure costs.

Can be locally heated

Being able to locally heat the workpiece, the process is flexible, saving heating time and cost.

Application case of induction preheating equipment

Induction preheating equipment is a type of air-cooled heating system widely used in various welding applications such as oil and gas pipelines, steel plates, steel structures, pressure vessels, etc. For example, in the preheating of oil pipeline welding, air-cooled induction heaters can quickly increase the pipeline temperature, reduce welding stress and deformation, and prevent the occurrence of cracks.

conclusion

Based on the above analysis, induction preheating equipment has become an indispensable part of modern welding processes due to its efficient heating capacity, precise control system, and environmentally friendly and safe characteristics. With the continuous advancement of technology, its application prospects in industrial production are broad, which helps to improve the quality and efficiency of welding work.
