  • How much do you know about brazing?
    Post time: 07-06-2023

    The energy source of brazing can be chemical reaction heat or indirect heat energy. It uses a metal with a melting point lower than that of the material to be welded as the solder. After heating, the solder melts, and the capillary action pushes the solder into the gap between the contact surface...Read more »

  • Harmful factors of welding materials, what should be paid attention to when using welding materials?
    Post time: 06-05-2023

    Harmful factors of welding materials (1) The main research object of welding labor hygiene is fusion welding, and among them, the labor hygiene problems of open arc welding are the biggest, and the problems of submerged arc welding and electroslag welding are the least.   (2) The main harmful fa...Read more »

  • How to choose DC and AC in welding?
    Post time: 05-25-2023

    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: 05-16-2023

    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: 05-16-2023

    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: 05-09-2023

    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: 05-09-2023

    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 ...Read more »

  • Do you really know anything about flux?
    Post time: 05-04-2023

         – FLUX– Flux is a granular welding material. During welding, it can be melted to form slag and gas, which plays a protective and metallurgical role on the molten pool. Constituent Flux is composed of marble, quartz, fluorite and other ores and titanium dioxide, cellulose and oth...Read more »

  • What kind of electrode is used for stainless steel welding? How to weld stainless steel?
    Post time: 04-26-2023

    Welding is a process in which the materials of the workpieces to be welded (the same or different) are combined by heating or pressure or both, and with or without filling materials, so that the materials of the workpieces are bonded between atoms to form a connection. So what are the key points...Read more »

  • Post time: 04-25-2023

    TIG 1.Application :       TIG welding (tungsten argon arc welding) is a welding method in which pure Ar is used as a shielding gas and tungsten electrodes are used as electrodes. TIG welding wire is supplied in straight strips of a certain length (usually lm). Inert gas shielded arc welding using...Read more »
