  • How to master the welding angle as soon as possible to avoid welding defects
    Post time: May-31-2023

    The so-called welding skills are simple welding methods, correct electrode angle and operation, and your welds will not be too bad. At the beginning of welding, due to the lack of mastery of the welding rhythm and unskilled handling techniques, it will cause pauses. If it is deeper and shallower,... Read more »

  • How to choose DC and AC in welding?
    Post time: May-25-2023

    Welding can use AC or DC welding machine. When using a DC welding machine, there are positive connection and reverse connection. Factors such as the electrode used, the condition of the construction equipment, and the welding quality should be considered. Compared with AC power supply, DC power s... Read more »

  • Selection of Tungsten Electrodes
    Post time: May-16-2023

    Red head thoriated tungsten electrode (WT20) Currently the most stable and widely used tungsten electrode is mainly used in the welding of carbon steel, stainless steel, silicon copper, copper, bronze, titanium and other materials, but it has slight radioactive pollution. Gray head cerium tungst... Read more »

  • All-round explanation of argon arc welding
    Post time: May-16-2023

    Argon tungsten arc welding uses argon as a shielding gas to heat and melt the welding material itself (it is also melted when the filler metal is added) by means of the arc generated between the tungsten electrode and the weld body, and then forms the welding of the weld metal Way. The tungsten e... Read more »

  • Basic knowledge of flux cored wire arc welding
    Post time: May-09-2023

    What is flux-cored arc welding? Flux-cored wire arc welding is a welding method that uses the arc between flux-cored wire and workpiece to heat, and its English name is simply FCAW. Under the action of arc heat, welding wire metal and workpiece are connected by melting, forming a weld pool, arc f... Read more »

  • Stainless steel how to choose welding material, do you really know?
    Post time: May-09-2023

    When welding stainless steel, the performance of the electrode must match the purpose of the stainless steel. Stainless steel electrode must be selected according to the base metal and working conditions (including working temperature, contact medium, etc.). Four types of stainless steel as well ...
