How Hard facing with 350LH Electrodes Saves Your Bottom Line
In the relentless world of heavy industry, the slow grind of metal against earth, rock, and ore is a quiet, constant drain on profitability. While catastrophic failures get immediate attention, abrasive wear is the silent budget killer, consuming parts, fuel, and man-hours with every cycle of your machinery. But there’s a proven, tactical defense: the strategic application of 350LH hard facing electrodes. This isn’t just repair; it’s a transformative maintenance philosophy. Beyond Repair: The Philosophy of Hard facing Traditional welding fixes what’s broken. Hard facing prevents it from breaking in the first place. It’s the difference between waiting for a component to fail and proactively armoring it against its specific enemy—whether that’s high-stress abrasion, moderate impact, or a combination of both. The 350LH electrode is engineered to be that armor. Why “350LH”? Decoding the Specs The name tells a skilled welder exactly what to expect: The Direct Line to Your ROI: Tangible Benefits Mastering the Application: The Art of the Layer Success with 350LH hinges on technique. Here’s how to ensure optimal performance: Spotting the Perfect Use Case: Is 350LH Right For You? The 350LH excels in a specific battlefield. It’s your go-to for severe abrasion coupled with moderate to heavy impact. Prime Targets for Reinforcement: When to Consider a Different Electrode: For pure, extreme-impact applications (like a crusher hammer in a shredder), an austenitic manganese steel electrode might be better. For extreme, low-impact abrasion (like a slurry pump), a higher-chromium alloy could be optimal. Conclusion: Don’t Just Maintain—Upgrade Using the 350LH hard facing electrode is a decision to move from reactive to predictive maintenance. It transforms your view of a worn part from “scrap” to an opportunity for an upgrade. You’re not just putting metal back; you’re putting back better, harder, and smarter metal exactly where it’s needed most. It’s time to see wear not as an inevitable cost, but as a manageable process. Equip your team with the knowledge and the right tools—like the 350LH—and turn your equipment’s weakest points into its most fortified assets.

What Is an E7018 Welding Electrode? A Complete Guide for Welders
If you’ve spent any time around welding shops, construction sites, or fabrication yards, you’ve likely heard of—or used—the E7018 electrode. Often called the “low-hydrogen” or “stick electrode of choice” for critical welds, it’s a staple in the toolkit of structural welders, pipeline welders, and anyone needing strong, ductile welds on carbon steel. But what exactly makes this rod so popular and trusted? In this complete guide, we’ll break down everything you need to know: from its classification and characteristics to its best applications, tips for use, and common challenges. Understanding the Code: What Does “E7018” Mean? The American Welding Society (AWS) numbering system tells you almost everything you need to know right on the rod’s coating. Key Takeaway: You’re looking at an all-position, low-hydrogen electrode that produces welds with 70,000 psi tensile strength using AC or DCEP current. Key Characteristics & Advantages of the E7018 1. Low Hydrogen Content This is its superpower. The coating is specially designed to minimize moisture absorption, which prevents hydrogen-induced cracking (HIC)—a major concern in thick materials, high-strength steels, and restrained joints. 2. Excellent Weld Quality E7018 produces smooth, clean welds with a fine ripple pattern, often described as “stacked dimes” in vertical-up welds. Slag removal is relatively easy. 3. High Ductility and Impact Resistance The weld deposit has good elongation (ductility), meaning it can flex and bend without breaking. It also maintains notch toughness at lower temperatures, making it ideal for structures subject to stress or cold environments. 4. High Deposition Efficiency The coating contains iron powder (typically 25-40%), which adds to the weld metal. This means you lay down more metal per rod compared to a non-iron powder electrode (like an E6010), improving speed and efficiency. 5. Smooth Arc & Minimal Spatter It has a stable, medium arc with very little spatter, leading to less cleanup time and a neater weld bead. Common Applications: Where Is E7018 Used? Because of its strength and reliability, the E7018 is the go-to rod for many critical welding jobs: How to Weld with E7018: Tips & Techniques Storage is CRITICAL! Machine Setup & Polarity Welding Techniques Challenges & Limitations Frequently Asked Questions (FAQ) Q: Can I use E7018 for everything?A: No. It’s not ideal for dirty, rusty metal or open-root joints where deep penetration is key. It’s a quality rod for quality work on prepared materials. Q: What’s the difference between E7018 and E7018-1?A: The “-1” designation (e.g., E7018-1 H4R) indicates enhanced impact toughness at lower temperatures, making it suitable for cryogenic or Arctic applications. Q: E7018 vs. E6013 – which is better?A: E6013 is an easy-to-use AC rod for light fabrication, thin metal, and hobbyist work. E7018 is stronger, more ductile, crack-resistant, and is used for structural and critical work. They are in different leagues. Q: How do I know if my rods are bad?A: If they’ve been out of the oven too long, you may notice difficulty striking an arc, excessive spattering, a porous weld bead, or steam coming from the coating during welding. When in doubt, re-bake them. Conclusion The E7018 is more than just a welding rod; it’s a symbol of quality and reliability in the welding industry. Its low-hydrogen properties, combined with excellent strength and ductility, make it the trusted choice for welding where failure is not an option—from skyscrapers to pipelines. Mastering the E7018 requires respect for its storage needs and practice with its technique. But for any welder looking to tackle serious fabrication, structural work, or critical repairs, becoming proficient with this electrode is an essential skill. Grab your rod oven, set your machine to DC+, and start practicing those smooth, strong beads.
