Clean Shielding, Reliable Coverage:
SVS Standards for Gas Nozzles
Gas nozzles with tight dimensional tolerances ensure a secure fit in the torch and precise shielding gas flow. Polished inner surfaces promote uniform gas distribution across the entire weld area. Heat-resistant materials maintain their shape even under high thermal loads.
For MIG/MAG welding, nickel- and chrome-plated versions are available to reduce spatter adhesion and extend service life. Alternatively, WIRBALIT® anti-spatter compound is recommended. For TIG welding, ceramic coatings are offered, providing high thermal resistance and reducing heat transfer to adjacent torch components.
Available as standard versions or custom designs based on drawings or samples. Geometry, interfaces, and materials are precisely tailored to your specific requirements.

Designs
Conical shapes focus the gas flow into a narrow area. This produces a compact protective atmosphere with precise alignment. This form is particularly suitable for welding in confined spaces.

Conical Gas Nozzles
Cylindrical shapes widen toward the outlet. They create a broad gas coverage and ensure a stable protective atmosphere across the entire weld zone. This form is suitable for applications that require extensive shielding gas coverage.

Coating Options
Used in TIG welding, this version provides reliable thermal protection, extends service life even under intensive use and reduces heat exposure to adjacent torch components.
In MIG/MAG welding, the nickel coating effectively prevents spatter from sticking to the nozzle surface and significantly extends its service life. Nickel also reflects a portion of the radiant heat, keeping the nozzle cooler and limiting thermal input from the welding process.
Chrome forms a hard, smooth surface that protects the nozzle from mechanical wear and reduces spatter adhesion. Especially under high cycle rates or frequent cleaning, the coating simplifies maintenance and ensures consistent gas coverage during MIG/MAG welding.
When using uncoated nozzles in MIG/MAG welding, WIRBALIT® anti-spatter compound can significantly reduce the adhesion of welding spatter. The nozzle is briefly dipped into the compound before welding. The resulting barrier layer prevents burn-in and makes post-weld cleaning easier.

Fundamentals
Function of Gas Nozzles in MIG/MAG and TIG Welding
The gas nozzle is located at the front end of the welding torch and surrounds the contact tip. It directs the shielding gas precisely to the weld zone and forms a consistent protective atmosphere that shields both arc and weld pool from ambient air. At the same time, it shapes and controls the gas flow while protecting the torch head from spatter and thermal stress.
Key Parameters of Gas Nozzles
The nozzle must distribute the shielding gas evenly along the weld zone. Even minor deviations in geometry noticeably alter the pressure distribution and gas coverage, weakening the protective atmosphere. The appropriate design depends on the torch type, distance to the weld, and the shielding gas used.
The inner surface must be smooth and free of residues. Irregularities or deposits disturb gas flow and reduce shielding effectiveness. High-quality finishes simplify cleaning and help maintain consistent gas delivery.
The material must withstand heat, wear and mechanical stress. Thermal resistance and dimensional stability determine the service life of the nozzle. A suitable material extends durability and keeps the process consistently stable.
