How to Reduce Welding Costs by Choosing the Right Filler Metals blog

1. How to Reduce Welding Costs by Choosing the Right Filler Metals A Strategic Guide for Fabricators, OEMs, and Welding Professionals In today's highly competitive manufacturing landscape, cost efficiency is more than just a financial metric—it’s a survival strategy. Among the many areas where manufacturers and fabricators seek savings, welding stands out as both a significant cost center and a major opportunity for optimisation. One often overlooked area of welding cost control is the selection of filler metals. Choosing the right filler metal doesn't just influence joint strength and quality—it directly impacts your welding speed, rework rates, energy usage, labor costs, and even regulatory compliance. In this article, we’ll show you how to reduce welding costs strategically by making smart choices about filler metals—featuring real-world insights, industry best practices, and supplier guidance from Rajiv Machine Tools, a trusted leader in welding consumables and equipment. ? Why Filler Metals Matter in Cost Control Filler metals are often treated as commodity items—bought in bulk with a focus on per-unit price. But that mindset can be expensive in the long run. Here’s how the right filler metal selection impacts your total welding cost: ● Reduces rework and defects ● Improves deposition efficiency ● Speeds up welding time ● Lowers spatter and cleanup time ● Minimises welder fatigue and training complexity Rajiv Machine Tools, with its range of premium welding consumables, offers technical consultation and product matching that helps you select the best filler wire, rod, or electrode for each application. Common Mistakes That Increase Welding Costs Before we get into how to cut costs, let's highlight some typical filler metal pitfalls that silently inflate them: 1. Using general-purpose filler for specialized metals

2. 2. Choosing based on price over performance 3. Ignoring deposition efficiency and operator appeal 4. Underestimating post-weld cleanup costs 5. Not aligning filler metals with welding process (MIG, TIG, SMAW) If you’ve encountered porosity, cracking, high spatter, or frequent grinding, your filler metal may be part of the problem. Understanding the Types of Filler Metals and Their Role Choosing the correct filler starts with understanding the different types and where they shine. 1. Solid Wires (GMAW/MIG Welding) ● Low spatter, high deposition rate ● Ideal for automated setups ● Example: ER70S-6 wires 2. Flux-Cored Wires (FCAW) ● Excellent for outdoor or high-speed applications ● Lower need for shielding gas ● Ideal for structural steel and heavy fabrication 3. Stick Electrodes (SMAW) ● Highly versatile ● Good for field welding and repair work ● Example: E6013 and E7018 electrodes 4. TIG Rods (GTAW) ● High-quality, precision applications ● Great for stainless steel, aluminum, and exotic alloys Every filler type has cost implications in terms of productivity, quality, and maintenance. Rajiv Machine Tools offers a full portfolio across all these categories, with both Indian and imported brands. How to Choose the Right Filler Metal (Key Criteria) 1. Base Metal Compatibility

3. Ensure filler metal matches or complements the base metal composition. Mismatch can cause brittle welds and corrosion. Tip: For carbon steels, ER70S-6 is versatile; for stainless, use ER308L or ER316L rods. 2. Welding Position Some wires and electrodes are designed for all-position welding (e.g., E7018), while others are best in flat or horizontal. Choosing an all-position filler when needed reduces time and errors. 3. Welding Process Match Not all fillers work across MIG, TIG, or Stick. Using a filler optimized for your process maximizes efficiency. Ask your supplier for process-specific recommendations. 4. Deposition Rate and Efficiency A 10% better deposition rate can reduce labor hours significantly. Look for specs on: ● Deposition rate (lb/hr) ● Efficiency (%) ● Arc time vs idle time 5. Cleaning and Pre/Post-Weld Requirements Some fillers tolerate surface rust and mill scale; others demand clean surfaces. This impacts your prep time and post-weld clean-up. For instance, ER70S-6 is forgiving on slightly rusted surfaces, while TIG wires require spotless metal. Real-World Example: Reducing Cost with Right Filler Choice A mid-sized fabrication unit in Pune was using standard E6013 electrodes for structural welding. After consulting Rajiv Machine Tools, they switched to low-hydrogen E7018 electrodes, which: ● Reduced rework by 60% ● Increased welding speed by 20% ● Cut post-weld grinding time by 40%

4. Result? A 15% reduction in total welding cost per unit. Additional Factors That Influence Filler Metal Performance 1. Storage and Handling Improper storage leads to moisture absorption and hydrogen-induced cracking—especially with low-hydrogen electrodes. Rajiv Machine Tools offers electrode holding ovens and storage solutions to prevent this. 2. Operator Training Choosing a user-friendly filler reduces training time and error rate. This is critical in high-turnover environments. Ask your supplier for demo runs or training videos. 3. Certifications and Quality Assurance Always use certified filler metals for critical applications (AWS, IS, ISO standards). Cheap or counterfeit wires can be catastrophic in pressure vessels, bridges, etc. Rajiv Machine Tools only supplies certified products from reputed brands like: ● Ador Fontech ● ESAB ● Panasonic ● Kobelco ● D&H Sécheron Why Choose Rajiv Machine Tools for Your Filler Metals?
