Welding technology is under the condition of high temperature or high pressure, the use of welding materials to connect two or more of the base material into a whole operation method, the use of welding electrode arc discharge generated by the heat will welding electrode and workpiece mutual melting and condensation after the formation of welding seam, so as to obtain a firm joint. Welding technology is the fastest and most comprehensive emerging processing technology using the latest science and technology. The current welding technology almost uses all available heat sources in the world, such as flame, arc, resistance, laser, electron beam and so on.The trucks and trailers produced in our factory are all kinds of automatic welding equipment and manual welding. There are three basic welding postures: squatting, standing and sitting.Generally standing and squatting are most widely used.
Process discipline is the factory in the process of production, in order to ensure the implementation of the process, to ensure the quality of products and safe and civilized production and the formulation of binding regulations, every welder before welding must be familiar with the welding process, welding quality standards, safe construction requirements and other knowledge, in the welding, must be strictly enforced. Welding process parameters are the general term of relevant parameters selected to ensure welding quality during welding. Each welding position and each piece of material with different thickness has its corresponding welding parameters, which must be timely adjusted by welding operators during welding.Only by adjusting the best welding parameters can we get a good weld. A good state of mind is an important factor in welding, before welding calm gas, welding process center no distractions, focus on the welding process.At the same time, we should maintain a serious and rigorous attitude towards work. We should not treat each weld with the mentality of completing tasks, but with the attitude of making handicrafts. We should be strict with ourselves and make up for our shortcomings by taking the advantages of others. In practice, the location of components, welding position will be different, welding personnel should be according to the site environment and find the best position of stability, flexible when necessary, make full use of the surrounding can rely on strong point, for example, when the person is standing, can use the left elbow to find rely on a fixed point, when people are in a squat position, can use both hands close to the knee on both sides, make the person, hand in the solid state.With the fulcrum, maximum stability can be ensured and jitter can be effectively avoided. Welding layer number of Angle joint or docking according to thickness and weld thickness, width of the welding layer of complete the whole weld, when can use multilayer multipass welding, should be used as far as possible, process of welding seam thickness should be slants thin, multi-layer multipass welding because of the weld bead welding bead first have tempering effect, can improve joint organization and mechanical properties, as well as the internal welding defects (not fusion) has a role in preventing.
