How To Choose Brazing Material Correctly When Welding Tool Steel And Hard Alloy With High Frequency

图片
  It is very important to choose brazing material correctly when using hf pvc welding machine . Selecting the right filler metal will not only improve the welding quality of the product, but also often improve the efficiency and save cost. This is more profitable for high frequency welder for sale . Therefore, in welding of the high frequency welding machine, we need to choose the solder properly according to the composition of the product and welding requirements. Liaoning Unify High Frequency Equipment Co.,ltd. is a professional high frequency welding machine manufacturing enterprise, devoted to one model of design, production, high frequency welder for sale, after - sales maintenance and repair.   High frequency welder usually uses pure copper, copper zinc and silver copper solder when welding tool steel and hard alloy. These three filler metals are highly correlated in composition and vary widely in price. Choosing the right filler metal is closely related to the welding cost. We n

Factors Affecting The Performance Of High Frequency Welding Machine

图片
  There are many factors affecting the effective power output of high frequency welder. Therefore, the major high frequency welding machine manufacturers  should pay attention in the production of high frequency welder. The effective output power of high-frequency welding machine is mainly affected by the following aspects:   1. Welding V Angle, the most economic and efficient Angle is between 2-3 °. In addition to electromagnetic induction heating, there are two important effects, namely skin effect and proximity effect of main principle of high frequency welding. The smaller the welding V Angle is, the closer the proximity effect will be, so that the effective output power of the welding machine can be used more effectively.   2. The shape of the two welded surfaces of the pipe should be parallel to each other. This will make the welding more efficient and the molecular diffusion between the two surfaces more uniform.   3. Welding temperature. Welding temperature plays a decisive rol

Main Characteristics Of Inflatable Welding Machine

图片
  Features of inflatable welding machine: 1. The operation of inflatable welding machine Inflatable welding machine has two push dials, two work bits. The operator only needs to put the products in it, push the push plate to trigger the micro switch, and the molds go down automatically, heat up, and go up. The whole process is simple and safe with high frequency. Staff can use the machine without special training.   2. Adjustment of output force of inflatable welding machine It adopts special low loss coaxial oscillator, which can adjust the output force at any time due to the size of the mold and the thickness of the glue. When you operate the inflatable welding machine, it will not cause interference with telecommunication with it. The adjustment of output can also be combined with the time system to maximize output. The heat sealing machine can weld the product in the shortest time and increase the production.   3. Protection device of inflatable welding machine A: current limiting

Structure And Working Principle Of High Frequency Welding Machine

图片
  Membrane hf welding machine  is the electromechanical system used to realize high frequency welding. The membrane welding machine is composed of high frequency welding machine  and tube welding machine. Membrane welding machine  is generally composed of two parts: high frequency generator and feeding device. Its role is to generate high frequency current and control it; the forming machine consists of an extruding roller stand. Its function is to squeeze the part that is melted by the high-frequency current.   1. High-frequency generator: in the past, the high frequency generator used on the welded pipe unit was three-loop and it's basically been improved to a single loop later. There are many methods to adjust the output power of high frequency oscillator, such as autotransformer, reactance method, thyristor method and so on.   2. Feeding device: it is used to transmit high frequency current to the tube, including electrode contacts, induction coil and impedance. In general, in

How To Solve The Welding Problems Of PVC Membrane Welding Machine

图片
  At present, pvc membrane welding machine  has been widely promoted in a number of plastic welding industry. Various welding defects are inevitable in the process of use. In this article, it mainly analyzes how to solve the problems in debugging or welding.   1. Crush and bruise Pressing injury and abrasion are common problems in the process of hf pvc welder . Sometimes it's not so serious, and it just gets white or marks. When you encounter such problems, the first thing to do is to ensure that the location of the tooling is not out of alignment. First let off the air of the cylinder, press down the welding head, and carefully observe whether the welding head position of the scratch is correct. If the welding head is in the correct position, or if the abrasion or compression occurs on the support (or lower cover), then it is necessary to observe whether there is any interference between the tooling and the product. If it is old tooling, it is suggested to clean the tooling with a

Structural Features And Application Range Of PVC Door Welding Machine

图片
  1.The basic principle of pvc door welding machine : This machine mainly adopts operating principle of high-frequency machine and radio   frequency. It makes use of the high - voltage transformer rectifier self - excitation high frequency tube oscillation moment to produce the high frequency electromagnetic wave current electric field. It makes use of processed materials PVC, TPU, EVA, PET in the field of high frequency electromagnetic wave, the internal molecules of plastic and plastic materials to produce polar heat conduction. Achieve welding sealing role of the plastics and plastic products needed for thermal welding by increasing some pressure.   2. Basic structure of pvc door welding machine: 1) the machine is mainly operated by double-head pedal pneumatic operation. The operation position is divided into the left and right sides of the handpiece. The operation table is designed with aluminum material, so that the electrical conductivity is more stable. The method of operation:
