EX4130-125T - Exocor ER4130 Chrome Moly TIG Rod 1/8"

Professional Grade ER4130 TIG Rods for Critical Fabrication

Take your fabrication projects to the next level with Exocor ER4130 TIG Welding Rods. Specifically formulated for welding 4130 and 4140 chrome-moly tubing and plate, these 1/8" rods are the go-to choice for fabricators building race car chassis, roll cages, aircraft components, and off-road suspension parts. When you are working with high-performance steel that demands strength and reliability, you need a filler metal that can keep up. Exocor delivers with a product that offers smooth feeding, stable arc characteristics, and exceptional puddle control.

One of the standout features of this ER4130 rod is its ability to be heat treated. If your project involves parts that will be hardened and tempered after welding, this is the rod you need. It ensures that the weld seam has similar hardness and strength properties to the surrounding steel, eliminating weak points in your structure. The 1/8" diameter is perfect for medium to thicker wall tubing and plate, allowing for efficient deposition rates while maintaining the precision TIG welding is known for. The rods come in a convenient tube packaging that protects them from moisture and contamination, ensuring they are ready to weld when you are.

Welding chrome moly requires skill and the right materials. Using generic mild steel rods on 4130 can lead to under-strength welds, while using stainless rods can cause cracking issues due to dissimilar thermal expansion. Stick with the proven solution: Exocor ER4130. These rods produce X-ray quality welds with excellent bead appearance, making your finished work look as good as it performs. Whether you are a professional motorsports fabricator or a dedicated hobbyist building a dream machine, trust Exocor to provide the consistency and quality you need to weld with confidence.
