Cleveland – Lincoln Electric strives to manufacturer the highest quality mild steel MIG wire to ensure customers industry leading performance. When manufacturing consumables like the company’s SuperArc® MIG wire, Lincoln Electric’s standards start with the raw material used to make the wire and end with the packaging and performance of the final product.
Raw Material Specifications: Steel Requirements
Because MIG wire only has three components – steel, plating, and surface lubricant – the steel has a large impact on the performance of the resulting weld deposit. The characteristic of steel that impacts the performance of MIG wire the most is its chemical composition. The chemical composition of steel is determined by the material used to create it and how it is processed.
Lincoln Electric’s steel analyst is present to ensure suppliers are using the correct raw materials and protecting molten steel from exposure to tramp elements during manufacturing. Monitoring the heat input during the rolling process avoids annealing and measuring cool-down rates achieves the correct ductility and surface appearance.
Production Standards: Quality Assurance
During steel manufacturing, two or three test samples are taken from the tundish containing the entire heat. Results of these tests are averaged and printed on a heat certificate which is attached to every bundle of steel produced from that heat. There is no governing body that regulates these certificates and no penalty for inaccuracy.
Most welding manufacturers rely solely on this heat certificate when using the steel to make their product. However, Lincoln Electric goes beyond industry standards and tests all incoming steel for 34 different elements instead of the 10 elements required by the American Welding Society (AWS). Steel is only used if it meets an extremely tight range for each element. These narrow ranges allow Lincoln Electric to fine-tune its products for maximum performance and ensure product consistency to its customers.
Innovative Processes: Manufacturing and Packaging
Lincoln Electric’s proprietary manufacturing technologies create the optimum surface conditions and keep SuperArc MIG wire at the top of its class. Precise wire diameter and surface finish is achieved with the diamond die skin pass before the wire is given its final surface coating.
All SuperArc products receive Microguard Ultra® Surface treatment to enhance welding characteristics like wire feeding and arc stability. The premium packaging solutions available for SuperArc wire are designed for feedability and precise wire placement. These packages also offer convenient storage and transportation capabilities as well as easy disposal.
The Lincoln Electric Company, headquartered in Cleveland, Ohio, is the world leader in the design, development and manufacture of arc welding products, robotic arc welding systems, welding fume control systems and plasma and oxyfuel cutting equipment. The company holds a leading global position in the brazing and soldering alloys market.
