  • Weld Visual Defect Measurement Technology
    Post time: 08-16-2023

    There is no difference in process between full argon arc welding and argon arc welding. Full argon arc welding is suitable for thin-walled small-diameter pipes (generally DN60 and below, wall thickness 4mm), the purpose is to ensure the quality of the weld root and the appearance. When the diamet...Read more »

  • The difference between fixed welding joint, rotating welding joint and prefabricated welding joint in pipeline welding
    Post time: 08-01-2023

    No matter where the welding joint is, it is actually an accumulation of welding experience. For novices, simple positions are the basic exercises, starting with rotations and moving on to fixed positions. Rotation welding corresponds to fixed welding in pipeline welding. Fixed welding means that ...Read more »

  • Detailed explanation of spot welding process
    Post time: 07-31-2023

    Spot welding is a resistance welding method in which the weldment is assembled into a lap joint and pressed between two electrodes, and the base metal is melted by resistance heat to form a solder joint.  Spot welding is mainly used in the following aspects:  1. Lap joint of sheet stamping parts,...Read more »

  • What points should be paid attention to in high carbon steel welding
    Post time: 07-18-2023

    High-carbon steel refers to carbon steel with w(C) higher than 0.6%, which has a greater tendency to harden than medium-carbon steel, and forms high-carbon martensite, which is more sensitive to the formation of cold cracks. At the same time, the martensite structure formed in the heat-affected ...Read more »
