When using ordinary welding equipment to weld nuts, it is easy to encounter problems such as disassembly and false welding. To overcome this problem, it has been replaced by more automated pipeline automatic welding robots. The results have significantly improved. The ability of welding robots is still better.
 Ordinary welding equipment is completely controlled by manual experience. Therefore, if the welding point of the nut is high or low, and the stability of the output and power supply of the device is not ideal, false welding is prone to occur. To prevent similar phenomena from occurring, on the one hand, stable welding points are required, and on the other hand, stable power supply and transportation are required.
  The pipeline automatic welding robot can achieve this. It can adjust the welding speed based on the current and voltage of welded workpieces with different materials and thicknesses to find suitable welding parameters, thereby reducing the possibility of welding defects.

  In addition to replacing equipment with pipeline automatic welding robots, the preparation work before welding nuts is also very important. Due to the welding part being made of aluminum and the presence of an oxide film on the aluminum surface, it is necessary to clean the oxide film before welding. Cleaning or pickling. Then, within three hours after cleaning the oxide film, use a welding robot to weld, otherwise new oxide films will be generated due to oxidation in the air, which will affect the actual welding quality.

  When the pipeline automatic welding robot uses non melting argon arc welding, the generated arc burns between the non melting electrode and the workpiece, and inert gas that does not react with the metal flows around the welding arc, forming a protective cover. That is to say, at this time, the pipeline automatic welding robot can prevent the high-temperature metal in the tungsten * * * part, arc and molten pool, as well as adjacent heat affected zones, from coming into contact with the air, thereby preventing oxidation and absorption. Harmful gases can form dense welded joints. And demonstrate better mechanical performance.
  When the pipeline automatic welding robot uses argon arc welding for welding, the welding wire will be fed through the welding wire wheel, and the conductive nozzle will conduct electricity, generating an arc between the base material and the welding wire, melting the welding wire and the base material, and using inertia. Argon gas protects the arc and molten metal for welding.
