Argon: The Universal Baseline Pure argon is the most common and versatile shielding gas for stainless steel, particularly for TIG (GTAW) and plasma cutting. The Optimal Mixtures for MIG and TIG For MIG welding (GMAW), the standard industry practice is a tri-mixture of Argon, Carbon Dioxide, and Oxygen.
Ensuring Weld Cleanliness with the Right Shielding Gas
This is essential for welding thick stainless steel plate efficiently, but it comes with trade-offs, such as increased spatter and a slightly more demanding setup to manage the higher heat input. Practical Considerations and Troubleshooting.
The Helium Advantage for High-Heat Applications When tackling thicker sections or requiring deeper penetration, helium becomes an invaluable component. For critical applications, you should demand a minimum of 99.
Ensuring Weld Cleanliness with the Right Shielding Gas
Selecting the correct shielding gas is the single most critical variable when achieving high-quality, clean welds on stainless steel. Unlike mild steel, stainless steel is highly susceptible to atmospheric contamination, which can quickly ruin the protective oxide layer and lead to disappointing results.
