Welding positioner advantages
19 Jul 2019
The welding positioner is a device that makes the weld be horizontal or boat-shaped by the rotation or inclination of the working day. The rotation of the table adopts the frequency conversion stepless speed regulation, and the tilting is driven by the sector gear or the hydraulic cylinder, and the operation machine can realize the joint control. The advantages of welding positioner are as follows: 1. The operation is simpler and the performance is stable. The positioner is made according to the specific needs of different manufacturers, so the overall operation is also designed according to the habits of the merchants. This kind of equipment is simpler to operate, more stable, stable in performance, and can ensure the overall working efficiency, which is very suitable for everyone to choose. 2. Simple maintenance and long service life. The equipment has undergone an overall innovation, the quality of the new product is better, and it is more stable. It only needs to be used according ...
Welding manipulator selection tips
13 Jul 2019
In the processing of metal materials, the welding process is indispensable, so the automatic welding machine has become one of the important components in the material production line. It conforms to the material welding process. If the quality of the automatic welding machine is not up to standard, not only will it be Reducing the quality of the weld will also affect the entire process. Therefore, we should pay attention to the following points when choosing the welding operation. When choosing an automatic welding machine, we must pay attention to the influence of the brand. The quality of the brand manufacturer is also guaranteed. The quality of the equipment is the life of the production line and the guarantee of efficiency. Therefore, in the process of selecting an automatic welding machine, priority should be given to equipment manufactured by large brand regular manufacturers. Secondly, we must pay attention to the service and after-sales service of the automatic welding machine...
Working principle and technical requirements of welding machine
05 Jul 2019
The welding machine can weld all kinds of welds and various methods to metal containers and metal welding dismantled parts. Widely used in wind power equipment, pressure vessels, petrochemical pipelines, steel structures, boilers, shipbuilding, surfacing repair and many other industries. The welding positioner is a universal and efficient welding equipment for ring seam welding. First of all, because the welding machine uses a hydraulic transmission, combined with a highly integrated valve block and a large flow path, the pressure loss of the entire system is much reduced; the sealing performance of the welding machine is very high. Mainly used are imported components imported from abroad. Secondly, the oil temperature can be well controlled, because the oil circuit of the welding machine is designed with clever ideas, so that the entire hydraulic system presents a good appearance, even if it is used for a long time, there will be no big problems. The operating system of the welding ma...
The basic principle, characteristics and use of electron beam welding
29 Jun 2019
The basic principle, characteristics and use of electron beam welding Electron beam welding utilizes a high-speed electron beam that is focused in a vacuum to bombard the surface of the weld, causing it to melt instantaneously and form a welded joint. Electron beam welding has the following characteristics: 1) High energy density and strong electron penetration; 2) The welding speed is fast, the heat effect is cancelled, and the welding deformation is small; 3) The vacuum protection is good, the weld quality is high, and it is especially suitable for the welding of living wave metal. Electron beam welding is used to weld low alloy steel, non-ferrous metals, refractory metals, composite materials, dissimilar materials, etc., thin plates and thick plates. It is especially suitable for welding thick parts and welding parts requiring small deformation, using devices in vacuum, precision micro-devices, etc.
What is the basic principle of laser welding
21 Jun 2019
What is the basic principle of laser welding? Laser welding uses a focused laser beam as an energy source to bombard the heat generated by the workpiece for welding. Laser welding has the following characteristics: 1) The laser beam has high energy density, the heating process is extremely short, the welding point is small, the heat affected zone is narrow, the welding deformation is small, and the weldment dimensional accuracy is high; 2) It is possible to weld materials that are difficult to weld by conventional welding methods, such as welding refractory metals such as tungsten, molybdenum, niobium, and zirconium; 3) It is possible to weld non-ferrous metals in the air without the need for additional protective gas; 4) Laser welding equipment is more complicated and costly. Laser welding can weld low-alloy high-strength steel, stainless steel and copper, nickel, titanium alloy, etc.; dissimilar metals and non-metallic materials (such as ceramics, plexiglass, etc.); currently used in...
The type of resistance welding and the applicable occasions
15 Jun 2019
Resistance welding is a welding method in which a current is passed through a resistance heat generated between a workpiece and a welding contact surface to heat the weldment to a plastic or partially melted state, and then pressure is applied to form a welded joint. Resistance welding is divided into three types: spot welding, seam welding and butt welding. (1) Spot welding: the weldment is pressed between the two columnar electrodes, and is heated by electricity to melt the weldment at the contact to form a nugget, then power off, and solidify and crystallize under pressure to form a dense joint. . Spot welding is suitable for welding thin plates (laps) and steel bars up to 4 mm, and is widely used in the production of automobiles, airplanes, electronics, instruments and daily necessities. (2) Seam welding: Seam welding is similar to spot welding except that a rotating disk electrode is used instead of the column electrode. The stacked workpieces are energized between the discs and f...
