Welders often have a question - what characteristics and properties have the greatest influence on the quality of the welding wire? Based on extensive practice, we can say that the most important qualitative properties of welding wire are: 1. Chemical composition. Carbon 0.05-0.15%, Manganese 1.4-2.1%, Silicon 0.7-1.2%. The presence of other elements, especially sulfur and phosphorus, is preferably in the minimum possible amount. 2. The surface of the welding wire must be cleaned of technological grease after drawing, but at the same time the surface must provide the maximum possible sliding while passing inside the current-carrying tip. That is, it is necessary that the friction between the welding wire and the current-carrying tip is minimal. Moreover, it should be noted that the welding wire simply cleaned of technological grease has a rough surface and strong friction with the current-carrying tip. Our know-how is non-coppered polished welding wire, which ensures the best possible contact during welding, minimal friction between the wire and the current-carrying tip and no contamination of the tip. 3. straightening - the formation of the wire in two planes during winding on coils is necessary so that the welding wire comes out of the current-carrying tip evenly without twisting. If you wind 3-5 meters of wire from a coil and lay it on the floor, then with good alignment, the wire should curl into a ring with a diameter of at least 0.5 meters without loosening the turns. If the turns of the wire are loosened and the ring is not formed, then when exiting the current-carrying tip, such a wire will twist a lot, and the welding seam will be uneven. 4. Row-to-row winding on the coil provides the most stable wire feed during welding

There is a widespread misconception that a copper coating is applied to the welding wire in order to protect it from moisture and corrosion. As a manufacturer of copper-plated welding wire, we inform you that the copper-plated coating is applied exclusively as one of the ways to improve the contact during welding between the welding wire and the current collector tip. In practice, with direct contact with the surface of the welding wire of water, moist air, fog, the copper-plated welding wire starts to rust more quickly and more strongly than the cleaned polished welding wire. The most effective protection against corrosion is high-quality packaging and the addition of silica gel under the packaging. We pack the welding wire as follows - we immerse the coil with the welding wire wound on it into a plastic bag, add silica gel inside and seal the open part of the bag, then put it in a thick cardboard box. The consumer needs to know that in any case, the welding wire must be stored in covered rooms without high humidity
