Welding Shielding Gases Overview🔥 Many think welding is all about heat, skill, and filler metals—but shielding gases quietly play one of the most critical roles. Without the right shielding gas, even the best welder and equipment can produce defective welds. 🎯 Here’s why shielding gases matter 👇 ✅ Protect the Weld Pool They create a barrier against oxygen, nitrogen, and moisture that cause porosity, oxidation, and brittleness. ✅ Stabilize the Arc They ensure smooth arc characteristics and con
