What’s the Best Gas for MIG Welding - Vern Lewis Welding Supply
WebJun 24, 2024 · When welding mild steel you typically use what’s called C25 gas (25% CO2 and 75% argon). For aluminum MIG welding you would use pure argon shielding gas. This will allow the spray transfer process to occur. For thicker aluminum (1/2” or more), anywhere from 25% to 75% helium is added. This allows for deeper penetration into the workpiece. WebScore: 4.6/5 (35 votes) . TIG welding is used in high-tech, high-impact industries like automotive and aerospace because of its ability to produce strong, quality welds on thin materials. Since the operator has manual control over the filler metal, the beads can be much smaller and cause less disruption in the surrounding metal. WebApr 10, 2024 · A mix of 75% helium and 25% argon is ideal for welding aluminum because it provides the right amount of heat and penetration. Keep in mind that the gas flow rate should be around 20 cubic feet per hour. Use a high-frequency start: A high-frequency start helps to create a stable arc and can also help to break up the oxide layer on the aluminum. book a library space uni of liverpool
