The flexibility of welding robots can affect product quality

The flexibility of welding robots can affect product quality. After manual welding, if there is a yellow covering on the surface of the weld seam, please pay more attention to the welding robot to avoid similar problems and ensure that the welding quality meets the standards. We need to know that this yellow substance is actually an impurity in the welding wire and welding base material, mainly due to the high-temperature oxidation of silicon and manganese during the welding process, as well as the chemical reaction with CO2 in the protective gas, which decomposes to form silicon oxide and manganese oxide. It is somewhat similar to welding slag in manual welding. Although these phenomena can occur even when using welding robots, these oxides will not have any adverse effects on welding quality except for a few defects, and can be easily removed with a brush. There will be some silicon manganese elements in the metal elements of the welding base material. This phenomenon will definitely exist. If you want to reduce these oxides, you can choose welding wires with less silicon and manganese elements, and use welding wires with less carbon dioxide content instead of shielding gas. Using a mixed gas will reduce the oxide content in welding and reduce macula.
