Also known as high-frequency induction heating frequency welding, high frequency welding is the use of 10 ~ 500KHz frequency current flows through the metal connecting surface to generate heat resistance and applied (or not applied) pressure welding method to achieve a metal binding. Its characteristics are: welding speed large and small weld heat-affected zone, the workpiece can not clean up the welding, welding thin-walled tube, welding metal pipe. Moment in the implementation of pipe welding, high frequency welding of the fastest and most effective form of a welding. However, the implementation of high-frequency welding pipe at the moment, also revealed a variety of different issues and lacking. Therefore, the initiation of high-frequency welded pipe in a little debris, synthetic one is not sufficient, such as the implementation of a comprehensive analysis of the situation of things, summarizing the generalization welding, pipe end is the lack of initiation and to avoid the initiation of a lack of approach.
High frequency welding technology is passed to the molding machine, the latter forming a circular tube, and then through an induction loop, etc., the initiation of an induced magnetic field current, let it go through the whole child strip edge, and then, at the edge of the strip will, an initiation of thermal resistance, also called the heating, the edges of the strip such heating, then after extrusion, will form a weld. However, if the curb is very bad at the moment produced, it will likely face in the synthesis of one of the first molten metal left over from the next point, or oxygen compounds. This is because the edge of the strip into the current still in place at the bottom edge of the strip, either a good longevity, the calories in the welding time, the implementation of the edge profile pieces, and then in the cool of the moment, they will be drawing on the edge of the strip, longevity an oxygen compounds. But then the local pipe welding lack of time, due to the implementation of the installation and commissioning crew inappropriate moments caused, and to pick a reasonable solution to the usual operation for the purposes of analysis and testing, etc., and to the growth of welders professional skills, which are helpful in a lack of effective forms of impairment. And, you can also grow through the edge of the cutting edge as well as the quality of disposal, as well as energy storage coil with experience, so you can derogate from the edge of the place revealed damage.
