The electric heating tube is a kind of electric heating equipment often used in our life, and welding is a very important step in its production process. Most of the system is transported by pipes, and its temperature and pressure are relatively high during use, so welding is particularly important. The quality of welding will directly affect the use of the entire equipment, so it is necessary to do a good job of welding.
Welding mainly exists between the pipe and the pipe, the connection between the pipe and other components, it can actually be said to be a local rapid heating and cooling process, the welding area is constrained by the surrounding body, unable to expand and contract freely, after cooling, it will produce welding stress or even deformation. Therefore, when welding some important products, it is necessary to eliminate welding stress to avoid deformation.
At present, welding technology has been greatly improved compared with the past, can make mechanical properties equal to or higher than the connected body, and no defects inside and outside the weld. The strength of the joint will be affected by various factors, such as the quality of the weld, the force, the working environment and so on. The basic forms of joint mainly include butt joint, lap joint, corner joint and so on.
Although in metal processing, the development of welding process is relatively late, but in fact, the development speed is very fast. In the future welding process, on the one hand, it is necessary to further develop new welding methods and welding materials to improve the quality, safety and reliability of welding; On the other hand, it is also necessary to improve the level of welding mechanization and automation, and realize the program control and digital control of the welding machine, so that the welding conditions can be greatly improved.
The use of The flange immersion heaters is related to the safety of users, so users need to pay attention to the welding process in the manufacturing process and all kinds of small details in the use process. In order to ensure the safety of use, it is recommended to make use of the products regardless of selection or use. It has to be done the right way.
