High-speed steel welding seam metal is an important class of high-speed production equipment belonging to the working principle of the scope of resistance welding; that the combination of work, put pressure on the electrode through the use of current flowing through the joint contact area and close to generate heat resistance, Overlap each other to form a series of nuclear fusion and access to the gas-tight seam. The welding equipment to use this method for rolling welding seam, for the cylindrical roller electrode, the width of the plate than some of the lap joints in order to control the thickness, the use of welding electrodes greater pressure and continuous welding current.
Through strict control of welding norms, including the electrode pressure, including pressure on the electrodes, welding current, welding speed, and other parameters can be achieved stability in the quality of welding. This set of equipment feed, reel, welding, weld rolling, such as discharge functions, is the type of vertical metal weld high-speed automatic welding of complex mechanical and electrical integration of Seam Welding equipment, as well as advanced foreign technology and technology The introduction, digestion and absorption, for the better of a case in point.
DC power inverter resistance spot welding using IGBT inverter technology, computer control technology and the power of modern electronic technology to develop a new type of self-power, high efficiency, high power factor and precise control characteristics. Particularly suitable for copper, aluminum, nickel, molybdenum and other precious metals and alloys for spot welding suitable for precision welding and auto components of the application of welding.
