The main component of the pe butt welding machine is a step-down transformer. The two ends of the secondary coil are the welded workpiece and the electrode, which ignites the arc during operation, and welds the electrode to the gap of the workpiece under the high temperature of the arc. Because the iron core of the electric welding transformer has its own characteristics, it has the characteristic of a sharp drop in voltage, that is, the voltage drops after the electrode is ignited; when the electrode is short-circuited by adhesion, the voltage drops sharply. Next, the editor will introduce the principle of pe butt welding machine and the advantages of pe butt welding machine.
Principle of pe butt welding machine
The pe butt welding machine actually uses the resistance to generate heat when the workpiece is in contact with each other, so as to achieve the purpose of heating the workpiece and melting the metal surface. The weld is formed under the condition that the solid metal of the workpiece is plastically deformed. Common crystal grain, weld structure and composition are close to basic metals, so it is easier to obtain iso-strength and iso-plastic welded joints. In the flashing process, it has the self-protection function of exhausting air and reducing metal oxidation, so that there are fewer defects such as weld inclusions and incomplete penetration.
