* Workbenches are usually made of steel. Steel is often welded using shielded metal arc welding (SMAW) or gas metal arc welding (GMAW), which use different shielding gases than argon.
* Argon is primarily used for welding aluminum and stainless steel. These materials require a shielding gas that prevents oxidation and contamination during the welding process.
* Recycling workbenches are usually made of standard steel. They don't require the specialized welding techniques and shielding gases used for aluminum or stainless steel.
Instead of argon, you would likely see these gases used in welding workbenches at recycling companies:
* CO2 (carbon dioxide): This is a common shielding gas for welding mild steel using GMAW.
* Argon-CO2 mixtures: These mixtures are also used with GMAW for welding steel.
* Flux-cored wire (FCAW): This welding process uses a wire with a flux coating that provides shielding without needing a separate shielding gas.
It's important to note that the specific welding techniques and shielding gases used may vary depending on the specific steel being welded and the welding equipment available.
