Basic knowledge of welding

  Welding is a very important manufacturing process, it is a method to join two or more workpieces together, especially in the metal manufacturing industry, is one of the indispensable processes. From building structures to automobiles to the manufacture of household goods, welding plays an important role.

  First of all, let's take a look at common welding methods. The most common is arc welding, which uses an arc to create a hot heat source between the electrode and the workpiece, melting it to form a weld. Another common welding method is gas shielded welding, which uses gas to protect the welding area to prevent oxidation. There are also many other types of welding, such as laser welding, friction welding, resistance welding and so on.

  There are some important parameters to control when welding, including current, voltage and the speed of the welding machine. These parameters have a direct impact on the quality of the weld and need to be adjusted according to the material and size of the workpiece and the shape and position of the weld.

  Safety in welding operations is also an issue that needs attention. A large amount of ultraviolet light is generated during welding, so special protective equipment is needed to prevent injury. At the same time, the welding process will also produce harmful smoke, so it needs to be carried out in a good ventilation environment, and the corresponding smoking equipment should be used.

  Finally, welding operations also need to have a certain skill. The welding tool needs to maintain a certain Angle when welding, which is very important to ensure the quality of the weld. The speed of welding also needs to be controlled, if it is too fast, the weld will break, and if it is too slow, it will cause overheating and burning through.

  The above is some of the basic knowledge about welding, mastering this knowledge will help you better understand and operate welding equipment. Let's continue to learn and explore more mysteries of welding technology.
