Induction heating treatments for welding can be a powerful tool to help reduce costs and increase quality. Induction technology can provide precise heating that allows welders to concentrate heat where it is needed, rather than across the entire surface of the material. This helps reduce distortion and improves overall strength of the weld. Unlike other heating methods, induction doesn’t require lengthy preheating and cooling cycles, saving time and money.
Which are the most common heat treatments for metals?
Induction heating works by creating an electromagnetic field around a metal conductor. This causes eddy currents to flow through the material, which then generates heat. This is similar to how a magnetic field works on an iron nail, making it easy for operators to use. The eddy currents created by induction are fast, which allows the material to heat up quickly. This saves time and reduces labor costs for welders.
Welders often preheat the material before welding to make sure it reaches the desired temperature for the weld. Using an induction process for preheating can decrease the temperature difference between the arc and the base material, which can reduce cracking. It can also reduce the amount of hydrogen in the weld, which can cause problems.
Induction technology is used for a variety of welding applications, including pipe, flat plate, elbows and valves. It can be used on a wide range of materials and shapes, with the ability to vary the frequency and intensity to suit the needs of the application. It also delivers better results than other heating methods for the same task, such as flame or resistance.
