  • What are the characteristics of flux

    What are the characteristics of flux

    2020-07-29 585

    &Welding materials usually contain flux. Flux is usually a mixture of rosin as the main component, which is the auxiliary material to ensure the smooth welding process. The main function of flux is to remove the oxide on the surface of solder and base metal (material) to make the metal surface reach the necessary cleanliness. It can prevent the re oxidation of the surface during welding, reduce the surface tension of solder and improve the welding performance. The performance of flux directly af

    The way of welding robot controlling molten pool temperature

    2020-07-17 581

    From the existing technology point of view, it is no longer a problem to realize the automation and intelligence of welding machine. The appearance of welding robot is a good proof. Even so, some of the core parts are strictly controlled, such as temperature. Because the temperature of its molten pool will directly affect the welding quality, and there are many interference factors, so it is difficult to control. However, the following measures are more effective, including: according to the spa

    1. Stainless steel welding strip can be divided into two types: titanium calcium type and low hydrogen type. DC power supply should be used for welding current during welding, which is helpful to overcome the redness of welding rod and penetration. The titanium calcium type coating welding material is not suitable for all-round welding requirements, only suitable for flat welding and fillet welding. 2. The surface of stainless steel electrode should be kept dry when it is used. In order to preve

  • What are the technical requirements for welding machines

    What are the technical requirements for welding machines

    2020-06-20 547

    Many people do not understand the welding machine. In fact, the welding machine is a new functional form formed by the combination of welding roller carrier and welding positioner, but it is not a simple external combination. Jiangmen Zhisheng will introduce some technical requirements of welding machine for you. Through these requirements, I hope you can have a general understanding of the welding machine. Similar to the welding positioner, the welding operator has the same technical requiremen

  • The importance of welding wire selection in welding

    The importance of welding wire selection in welding

    2020-06-10 563

    Do you know what requirements welding robot has for welding wire? Let's talk about the requirements of welding robot for welding wire. Welding robot can choose welding wire in barrel or in plate according to the needs. In order to reduce the frequency of changing welding wire, welding robot should choose barrel welding wire. However, due to the use of barrel welding wire, the feeding hose is very long and the resistance is high, so the quality requirements of welding wire stiffness are high. Whe

    Different materials and different welding methods

    2020-05-27 537

    Welding, also known as fusion and fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. So, when choosing welding materials, do you know which method to choose? Listen to Jiangmen welding processing editor. Due to the characteristics of high temperature, high pressure and strong corrosion of some devices, the intergranular corrosion, stress corrosion, high-temperature oxidation

    How to weld long rails

    2020-05-13 547

    1. The rail to be welded shall meet the requirements of relevant technical conditions for rail of new railway line. 2. Contact welding shall be adopted for rail welding at base. 3. The operators of welding equipment must receive professional training, be familiar with the quality standard of rail welding head, pass the examination of relevant departments, and obtain the operation certificate. 4. Operators must strictly implement the operation regulations of welding equipment and operate accordin

    Causes of cold crack in steel welding

    2020-04-08 505

    In the use of welding tools to carry out welding operations, in the process of steel welding, there are still steel cold cracking phenomenon. There are many reasons for this situation, which are generally related to the chemical composition, steel degree, preheating temperature and cooling conditions of steel. In order to maximize the occurrence of cold cracking phenomenon of underground steel, we must pay attention to the following points in technology: first of all, when welding steel, we shou
