Stress relieving and preheating parts play a crucial role in the welding process. Although the heating process sometimes poses challenges, induction heating can provide better consistency. It’s beneficial, especially when welders are working on different materials. But there are still people who hold a few misconceptions about it. Certain misconceptions are holding people back from realizing the benefits of induction heating. To better understand these myths, here are a few misconceptions about induction heating.
You can’t use induction heating on P91 pipe
Welders can in fact use induction to stress-relieve and preheat P91. It’s also applicable in other types of chrome moly pipe, too. Some experts say that the process behind induction heating doesn’t rely on flame or a heating element to transfer heat. Instead, the machine shop services in Trinidad use an alternating current that goes through the heating device. The process creates a magnetic field that surrounds the metal. The resistance that the metal builds fights against the heat flow, generating the heat in the specific part of the metal.
That’s why preheating these kinds of pipes are like heating other carbon steel pipes. You need to have high heat when you want to use induction on this kind of pipe. The temperature will help stabilize the heat in the entire interior part of the tube.
You can’t use the induction on plates
While most welders use induction in pipe welding heating, the procedure is also useful with flat plates, too. You can use it in other induction coil configurations such as placing it on top of a flat plate without wrapping it around the piece.
In addition, you can use induction coil configuration in heating more than one side of the plate. For example, if the welder is doing some work on one side of the flat plate, the induction coil can work on the other side by reheating it, helping the operator save time in setting up the other side.
It’s impossible to use induction with nonferrous metals
Another misconception about induction procedure is its ability to work with nonferrous metals. Aside from induction’s effectiveness on ferrous metals, Some people in the industry say that it’s also great in removing decals. You can use it to remove vinyl and banded trim. Welding operators can do it by winding more turns using the pancake coil or the solenoid. The procedure will generate a stronger magnetic field, helping the welder loosen up the material.
You must keep in mind that the induction method needs more time to set up. But the benefits of induction heating offset the time spent on the procedure. Induction provides more consistent heat throughout the entire area, helping to loosen up the material much faster. Also, induction heating can help the company save money, too.
These are a few of the most common misconceptions about induction heating systems and the truth behind each of them. It’s a flexible heating solution that can help you with your welding needs. It’s also the best choice if you need consistent heating with your project in the shortest possible time.
