Last Updated: January 2026 TIG welding cast aluminum can test your patience if the filler rod isn’t right. Cast alloys behave very differently from wrought aluminum, and the wrong rod often leads to a stubborn puddle, poor fusion, or cracking as the weld cools. That’s why filler rod choice matters so much with cast aluminum….
Last Updated: January 2026 Aluminum welding looks simple until the weld starts cracking or refusing to flow. That’s usually when filler rod choice comes into focus. Ask experienced welders what the most common aluminum filler rod is, and you’ll hear the same answers again and again. Most aluminum work revolves around a small group of…

If a helmet struggles to pick up faint arcs or gives a washed-out view, it shows up immediately in weld quality and eye fatigue. The best…
