How to choose and use the magnetic rod correctly?
How to choose the right magnet bar?
First of all, when choosing a magnetic rod, its appearance needs to obtain good straightness and meet the requirements of use.
Secondly, the surface of the magnetic rod is required to be dense, the grains are fine and uniform, no cracks, and the sound is crisp when tapped. For the size and shape of the magnet bar, the length of the magnet bar is selected according to the pipe welding machine.
How to use the magnet bar correctly?
There are two ways to keep the magnet bar magnetic during welding:
1. Use a magnet bar with a high Curie temperature.
2. Increase the water flow to effectively reduce the temperature of the magnetic bar during operation. The latter is an effective method of the former under certain conditions.
In addition, keeping the welding speed uniform during the welding process and matching the welding speed with the performance of the magnetic bar is also a problem that needs to be paid attention to when using the magnetic bar.
