$317.00/10lb tubeWhen you are fabricating a roll cage, a custom bicycle frame, or an experimental aircraft fuselage, you aren't just welding steel—you are engineering safety and performance. The Exocor ER4130 TIG Rod in 3/32" diameter is the professional fabricator's choice for welding 4130 Chromoly tubing and plate. This rod is designed to match the chemistry of your chrome-moly base metal, which means your welds won't just hold; they will perform. If you plan on heat-treating your part after welding to get maximum strength, this is the only rod you should be using. It hardens and tempers just like the steel around it, eliminating weak spots in your critical structures.
The 3/32" diameter is an excellent all-rounder, perfect for the wall thicknesses typically found in chassis tubing and brackets. It offers a smooth, stable arc when used with 100% Argon shielding gas, allowing for that stack-of-dimes look that every TIG welder strives for. The rod flows cleanly and wets out the toes of the weld nicely, reducing the chance of stress risers which are the enemy of high-performance parts. Each 10lb tube is packed to keep the rods straight and clean, ensuring you don't introduce impurities into your puddle.
Welding Chromoly is different from mild steel. It loves to crack if you shock it with cold air. Always make sure your fit-up is tight—gaps are your enemy here. We recommend a little pre-heat on the metal (a propane torch works fine for thinner tubing) to take the chill out before you strike an arc. Once you finish a weld, don't let a draft hit it. Let it cool down slowly. If you do this, the Exocor ER4130 rod will give you a joint that is as tough as the rest of your build. Whether you are in the pit lane or the hangar, trust Exocor to keep your project together.
