  • What are the shielding gases used in TIG welding?

  • Recommendations for shielding gases used in TIG welding of different stainless steels are given in the table. For plasma-arc welding, the gas types with hydrogen additions in the table are mostly used as plasma gas, and pure argon as shielding gas.

  • What is the purpose of the shielding used in welding?

  • Shielding are mainly used to protect the molten metal from the contamination and oxidation caused by these harmful gases in the atmosphere: Why does any of this matter? The properties of various gases used in welding training are applied in real-world welding projects.

  • What causes excessive shielding gas usage in welding?

  • The shielding gas flow rate, using a conventional flow meter or with a mechanical antisurge device installed, is usually set sufficiently high to take into account the highest welding current being used, which consequently results in an excessive usage of shielding gas [48].
