Gas lens

A gas lens in a TIG torch is a fine mesh that ensures a uniform and swirl-free shielding gas flow. This improves the shielding gas coverage of the weld and prevents porosity.

Physicochemical Mechanism of Action

The gas lens in a TIG torch is a fine mesh that regulates the shielding gas flow. It prevents turbulence and ensures a uniform gas coverage of the weld.

Metallurgical Relevance & Risks in Welding

A swirl-free shielding gas flow prevents porosity and improves shielding gas coverage. Without a gas lens, uneven gas coverage can occur, leading to porosity and contamination.

Workshop Practice & Instructions

Make sure the gas lens is clean and undamaged. A defective gas lens can lead to uneven shielding gas flow and porosity. Replace the gas lens if necessary.
