Welding is the process of joining two metal components together through local heating. The temperature at the fusion point can reach 4000 to 6000 degrees. At present, we offer CO2 gas welding, arc welding, laser welding, friction welding, TIG welding, projection welding, stud welding, etc. for different situations. Nowadays, robotic welding machines can replace some manual operations and achieve consistent welding quality. Choosing the appropriate welding material is crucial for the quality of the welding seam. In addition, weldment is prone to thermal deformation, we need to prepare corresponding welding procedure and specialized welding fixtures to ensure welding quality, or arrange the heat treatment after welding, and machining of some critical features to ensure customer required dimensional tolerances. Currently, our welding parts mainly serve agricultural machinery, construction machinery, automotive parts, communication electronics chassis, and some non-standard metal structural components
