Welding Wire

Joining Monel to steel is one of the trickiest jobs a fabricator faces. You are welding two very different metals, and the filler wire you pick decides whether the joint holds or cracks in service. Pick the wrong wire and you get porosity, cracking, or a weld that corrodes fast. This guide covers which filler wire to use for Monel to steel, and the step by step procedure that gives you a sound, reliable joint. Why Welding Monel to Steel is Difficult Monel is a nickel copper alloy built for seawater and chemical service. Steel, whether carbon or stainless, behaves very differently under the arc. When you melt them together, three problems show up. Iron from the steel dilutes into the weld and can lower its corrosion resistance and toughness. Nickel copper weld metal is sensitive to sulphur, grease, and other contamination, which causes hot cracking. The two metals expand

Monel filler wire is the go-to consumable for welding nickel-copper alloys used in the world’s harshest marine and chemical environments. The most widely specified grade is ERNiCu-7 – a titanium-bearing nickel-copper wire that produces dense, porosity-free welds with excellent seawater and acid resistance. This guide explains ERNiCu-7 Monel filler wire – its composition, grades and forms, key applications, and exactly how to choose the right one for your job. What is Monel Filler Wire (ERNiCu-7)? ERNiCu-7 (UNS N04060), commonly known as Monel Filler Metal 60 or Alloy 60, is a nickel-copper filler wire classified under AWS A5.14 for TIG (GTAW) and MIG (GMAW) welding. It is the matching filler for welding Monel alloy 400 and other nickel-copper alloys. Its defining feature is a controlled addition of titanium, which deoxidises the weld pool and prevents the porosity that plagues nickel-copper welds made with base-composition filler. The result is sound, corrosion-resistant weld

Inconel 625 (Alloy 625) is one of the toughest nickel-chromium-molybdenum superalloys to weld well – it is sluggish in the weld pool, sensitive to contamination, and unforgiving of excess heat. Get the filler wire, shielding gas, and heat input right, and you get dense, crack-free welds with full corrosion resistance. Get them wrong, and you get porosity, hot cracking, and oxidised roots. This guide shows you exactly how to weld Inconel 625, the correct filler wire, machine settings, step-by-step technique, and the common mistakes to avoid. What is Inconel 625 and Why is it Hard to Weld? Inconel 625 (UNS N06625) is a nickel-based superalloy alloyed with chromium, molybdenum, and niobium. It is prized for outstanding corrosion resistance, high strength, and performance from cryogenic temperatures up to high heat – which is why it dominates petrochemical, marine, offshore, aerospace, and chemical applications. The same properties that make it valuable also

In stainless steel fabrication, selecting the right TIG filler wire is one of the most important decisions for weld strength, corrosion resistance, and long-term performance. Among the most widely used stainless steel TIG wires are ER308L TIG Wire and ER309L TIG Wire. Both are trusted across fabrication industries, pressure vessels, food processing units, pharmaceutical plants, petrochemical projects, and structural stainless steel applications. While both are high-performance stainless steel filler wires, they are designed for different welding purposes. Understanding when to use ER308L and when to use ER309L helps reduce weld failures, improve productivity, and ensure better service life. For fabricators, welding engineers, plant managers, and industrial buyers, this guide explains ER308L vs ER309L TIG wire, their differences, applications, and how to choose the right one. Fusion Wire by Shivshakti Metal offers premium stainless steel TIG/MIG welding wires including ER308L and ER309L for precision industrial welding applications. The catalogue highlights both

Choosing the right welding wire is one of the most important decisions in fabrication, construction, shipbuilding, heavy engineering, and industrial manufacturing. Among the most commonly used filler materials in industrial welding are solid wire and flux-cored wire. While both are used for strong and reliable welds, they perform differently depending on the environment, material thickness, and welding requirements. For plant managers, welding engineers, procurement teams, and fabricators, understanding the difference between solid wire and flux-cored wire helps improve productivity, reduce weld defects, and optimize long-term operational efficiency. This guide explains solid wire vs. flux-cored wire, their differences, advantages, applications, and how to choose the right one for your welding process. What is Solid Wire? Solid wire is a continuous, solid consumable welding wire mainly used in MIG welding (Gas Metal Arc Welding – GMAW). It requires external shielding gas such as CO2 or an Argon-CO2 mixture to protect the weld

Choosing the right welding wire is critical for achieving strong welds, better productivity, and long-term structural reliability. Among the most commonly used filler materials in industrial fabrication are MIG wire and TIG wire. Both are widely used across stainless steel fabrication, automotive manufacturing, pressure vessels, aerospace, oil & gas, and heavy engineering industries—but they serve very different purposes. For plant managers, welding engineers, procurement teams, and fabricators, understanding the difference between MIG wire and TIG wire helps improve weld quality, reduce rejection rates, and optimize production efficiency. This guide explains MIG wire vs TIG wire, their key differences, applications, advantages, and how to choose the right one for your welding process. What is MIG Wire? MIG wire is a continuously fed consumable welding wire used in MIG welding (Gas Metal Arc Welding – GMAW). It passes automatically through the welding gun and melts to form the weld joint while shielding
