6.5 grade precision car conductive nozzle

6.5 grade precision turning conductive nozzle is a welding accessory manufactured through precision suitable turning technology. Its main function is to conduct welding current to the welding wire and guide the welding wire to stably send out, confirming the stability of the arc. It is a key link to achieve high-quality welding.

Material and Craftsmanship

Purple copper/chromium zirconium copper: usually made of purple copper or chromium zirconium copper with better performance. Copper has good conductivity and thermal conductivity; Chromium zirconium copper, on the basis of conductivity, has high hardness and performance, and can adapt to high-frequency welding scenarios.

6.5 level precision machining process: Through precision machining, the inner hole size accuracy and surface smoothness of the conductive nozzle reach the 6.5 level standard. The clearance between the inner hole and the welding wire is small, which can reduce the frictional resistance when the welding wire is fed in, avoid wire jamming and deflection, and protect the stability of the arc.

structural design

Appearance: Generally cylindrical, with a threaded or snap on structure at one end, used to connect with the conductive seat of the welding gun; The other end is the outlet end for guiding the welding wire, which has undergone excellent processing to confirm the precise direction of wire feeding.

Inner hole: The inner hole is a smooth cylindrical shape, and the aperture is carefully designed according to the diameter of the suitable welding wire (such as 0.8mm, 1.0mm, 1.2mm, etc.), with strict tolerance control to adapt to different specifications of welding wire.

performance advantage

Excellent conductivity: The high conductivity of the material ensures stable transmission of welding current, stabilizes the arc, concentrates heat, and improves welding efficiency and quality.

Strong performance: The combination of precision machining technology and excellent materials gives it excellent performance, reducing inner hole wear caused by wire friction, extending service life, and reducing replacement frequency.

Smooth wire feeding: The precision appropriate inner hole design protects the smooth feeding of welding wire, avoiding arc interruption and welding defects (such as undercutting, lack of fusion, etc.) caused by poor wire feeding, especially in scenarios such as automatic welding and robot welding that require high wire feeding stability.

Application scenarios

Suitable for various gas shielded welding processes, such as CO ₂ gas shielded welding, mixed gas shielded welding, etc., especially in industries that require high welding quality, such as automotive manufacturing, engineering machinery, pressure vessel welding, etc., it can fully leverage its advantages of suitable precision and high stability.
