Nozzle for welding, sandblasting and spraying

Welding nozzles: In welding, ceramic nozzles are used to direct and control the gas stream as a shielding gas (most often argon or helium) to the protective atmosphere around the welding arc. These nozzles are critical to prevent oxidation of the welding area and maintain high-quality welding.

Sandblasting  nozzles: In sandblasting, ceramic nozzles are used to direct a high rate of abrasive media (such as sand or steel balls) at the surface of a workpiece to remove coatings, rust, or contaminants. Sandblasting and dispersion nozzles are made of alumina ceramics or composites consisting of alumina and chromium oxide that have very high hardness and wear resistance.

Ceramic sandblasting nozzles offer several advantages:

The great advantages of nozzles made of advanced ceramics are their high resistance to corrosion, to certain chemicals, to high temperatures, to abrasion and its improved toughness. Thanks to its hardness of 7 on the Mohs scale, abrasion resistance is more than 100 times higher than brass and between 20 – 30 times higher than stainless steel. This makes the material suitable for pressure washing. Alumina ceramics have been developed for specific purposes for the manufacture of welding nozzles and are characterized by high temperature resistance and electrical insulation resistance. We manufacture a range of standard types (or specific according to request) with threaded or cone shaped connection parts for MIG/MAG and WIG/TIG burners.

Technical ceramics offer several advantages in this context:

High temperature resistance: Ceramic welding nozzles can withstand the extreme temperatures generated by the welding arc without melting or distorting. This ensures that the gas stream remains stable and constant during the welding process.

Chemical stability: Ceramic materials are resistant to corrosion and chemical reactions, which is crucial when exposed to hot metal and hot welds.

Impact resistance: They are resistant to mechanical shocks and impacts, which is important because welding nozzles are often exposed to handling and use in harsh environments.

Accuracy: Ceramic nozzles can be manufactured with high precision and a smooth inner surface, allowing for a constant and even gas stream for optimal welding quality.

Wear resistance: Ceramic nozzles are durable and can withstand wear and tear from the abrasive media used in sandblasting, making them long-lasting and cost-effective.

Precise control: They provide precision and control over the beam of abrasive media, which is crucial to achieve the desired surface treatment.

Chemical resistance: Ceramic materials are resistant to chemical corrosion, making them useful for sandblasting surfaces that may be sensitive to chemicals.

Temperature resistance: They can handle the high temperatures that can occur during sandblasting, especially when hot workpieces are treated.

In summary, technical ceramics are of crucial importance in welding and sandblasting through its ability to provide high temperature resistance, chemical stability, wear resistance and accurate control. These properties allow high-quality welding and efficient surface cleaning in the manufacturing industry and many other technical areas. Using a ceramic nozzle will save operating and operating costs depending on the liquid being sprayed.
