These electrodes offer excellent corrosion resistance and are suitable for welding stainless steel structures. They come in various diameters, such as 2.5 mm, 3.2 mm, and 4.0 mm. The light coating facilitates smooth arc stability and minimal spatter.
Providing superior corrosion resistance, heavy-coated electrodes are ideal for high-stress applications. They are available in diameters of 3.2 mm, 4.0 mm, and 5.0 mm. The heavy coating enhances the weld’s integrity and improves its resistance to oxidation.
With excellent corrosion resistance, these electrodes are designed for shielded arc welding of stainless steel. They are typically available in 2.5 mm, 3.2 mm, and 4.0 mm. The shielded arc provides enhanced protection against contamination during welding.
We ensure full transparency of our AWS Class E320LR-16 Electrodes with high-quality assurance. All orders come with essential documents, including a commercial invoice, packing list, fumigation certificate, heat treatment chart and an NABL-approved lab test report. We provide a Material Test Certificate per EN 10204/3.1b, PMI Test Certificate, 100% radiography test report and Third-Party Inspection Certificate. Our comprehensive documentation is arranged to ensure maximum client satisfaction.
AWS Class E320LR-16 electrodes are used primarily for welding high-strength low-alloy steels, including those in construction and heavy equipment manufacturing.
