BAIJIAN - Third party testing organization
Covered electrode is a metal strip that melts and fills the joint of the welded workpiece during gas or electric welding. The material of the welding rod is usually the same as the material of the workpiece. According to different situations、 welding rods have different classifications、 and welding rods classified by performance are specialized welding rods manufactured based on their special usage performance、 such as ultra-low hydrogen welding rods、 low dust and low toxicity welding rods、 vertical down welding rods、 lying welding rods、 bottom layer welding rods、 high-efficiency iron powder welding rods、 moisture-proof welding rods、 underwater welding rods、 gravity welding rods、 etc. Covered electrode refers to the process of evenly and centripetally applying coating (coating) to the metal welding core. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the welding seam、 there are strict regulations on the content of various metal elements in the welding core、 especially for the content of harmful impurities (such as sulfur、 phosphorus、 etc.)、 which should be strictly limited and superior to the base material
