Welding electrode with functional coating

The disclosed technology generally relates to welding electrodes, and more particularly to consumable welding electrodes with functional coatings. In one aspect, a welding electrode includes a core wire having a base metal composition and two or more coatings covering at least a portion of the core wire. The two or more coatings comprise a conductive coating in addition to or different from copper (Cu), the conductive coating further comprising one or more conductive elements or compounds. The two or more coatings additionally comprise an additional functional coating comprising one or more additional elements or compounds adapted to alter the surface tension of droplets formed by the welding electrode. In another aspect, a method of manufacturing a welding electrode includes providing a cored wire having a base metal composition and forming two or more coating layers. 所披露的技术总体上涉及焊接电极，并且更特別是涉及具有功能涂层的可消耗焊接电极。在一方面，焊接电极包含具有基体金属组成的芯焊丝和覆盖该芯焊丝的至少一部分的两个或更多个涂层。该两个或更多个涂层包含导电涂层，除了铜(Cu)之外或者不同于铜，该导电涂层还包括一种或多种导电元素或化合物。该两个
