The welding rod (coveredelectrode) is formed by uniformly and centripetally pressing and coating a coating (coating) on a metal core wire outside the metal core wire. During welding, the core wire has two functions: firstly, the welding current is conducted, electric arc is generated to convert electric energy into heat energy, and secondly, the welding core is melted to be used as filling metal to be fused with liquid base metal to form a welding seam. When the welding rod is used for welding, the core metal accounts for a part of the whole welding seam metal. The coating is decomposed and melted in the welding process to form gas and slag, and the effects of mechanical protection, metallurgical treatment and improvement of process performance are achieved. The coating of the welding rod is an important factor for determining the quality of a welding seam, and has the effects of improving the stability of electric arc combustion, protecting a welding pool, ensuring deoxidation of the welding seam, removing sulfur and phosphorus impurities, supplementing alloy elements for the welding seam, improving the welding productivity, reducing splashing and improving the quality of the welding seam in the welding process.

It should be noted that the length of the metal core wire is greater than the length of the flux sheath, and during welding, a section of the metal core wire which is extended out is clamped on the electrode holder for conducting electricity, and then arc striking is performed. When the welding rod is burnt to a certain distance close to the clamping part, the high temperature generated by welding melting not only causes damage to the electrode holders, influences the service life of the electrode holders and causes cost loss, but also causes damage to welding workers due to the high temperature generated by welding melting. Therefore, when the distance from the electrode to the holding portion is short, for example, when the electrode is used up to 5 to 6cm, the electrode is directly replaced with a new one, and the replaced electrode is wasted as an electrode head, which results in a serious waste of resources.
