Basic working principle The basic working principle of Welding Wire is commonly used by 220V or 380V voltage industrial power through the welding in the regulator reduces the voltage to enhance the current use of electricity generated tremendous heat to melt steel, welding rod into the steel of the the integration between the higher, and, welding of the outer skin of the drugs played a very big role, do not believe you put the solder powder can not knock a look:). Of course, this interpretation is popular.
Types of welding More types of welding, the most commonly used are the following: arc welding, resistance welding, high-energy beam welding, brazing, electroslag welding, high frequency welding, gas welding, pressure welding, explosion welding, friction Cast Iron Electrode, ultrasonic welding, diffusion welding, etc.
This heat energy is the resistance Cast Iron Electrode of a class, including the slag resistance of heat energy to the solid resistance of electroslag welding and heat energy resistance welding. Resistance welding, including: resistance spot welding, coated welding, seam welding, high frequency welding, flash butt welding. As the electroslag welding more unique features, it is described later on. This introduces several solid resistance heat energy resistance welding, mainly welding, seam welding, projection welding, and welding and so on. Resistance welding is generally the workpiece at a certain electrode under pressure and use of current through the resistance of the workpiece when the heat generated by contact between the two parts to connect surface melting and welding methods. Typically use a larger current. In order to prevent occurrence of arc in the contact surface and weld metal for forging, welding process should always be pressure. For this type of resistance welding, the welder parts of the surface was good for a stable welding quality is of paramount importance. Therefore, the welding electrode and the workpiece before the workpiece and the workpiece and the contact between the surface clean. Spot welding, seam welding and projection Welding Electrode is the welding current of Wu (single phase) large (several thousand to tens of thousands of amperes), power-on time is short (a few seconds to wave a few weeks), expensive equipment, complex, high productivity and therefore suitable for large mass production. Mainly used for welding sheet metal components of thickness less than 3mm. Various types of steel, aluminum, magnesium and other nonferrous metals and alloys, stainless steel can be welded.
