Problems solved by technology

With the continuous development of industrial technology, people have created high-quality thick-coated electrodes that are widely used. Once the thickness of the coating reaches a certain level, the requirements for bonding between the coating and the welding core are getting higher and higher. If the coating and the welding core cannot be effectively bonded, it will lead to the failure of the entire electrode, and even if there is a partial peeling between the coating and the welding core during use, unpredictable consequences will occur

Embodiment Construction

[0010] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings of the embodiments.

[0011] Such as figure 1 As shown, a thick-coated electrode according to the present invention includes a welding core 1 and a thick coating 2 adhered to the surface of the welding core 1 ; grooves 3 are provided on the surface of the welding core 1 .

[0012] Preferably, the cross section of the groove 3 is semi-circular or semi-elliptical, which ensures the normal combustion of the electrode and ensures the welding effect.

[0013] Preferably, the number of the grooves 3 is 8-10.

[0014] The above is only a specific embodiment of the present invention, and the protection scope of the present inv...

Abstract

The invention relates to a welding rod, and particularly discloses a welding rod with a thick coating. The welding rod comprises a welding core and the thick coating adhered to the surface of the welding core, wherein grooves are formed in the surface of the welding core. According to the welding rod with the structure, the grooves are formed in the welding core, so that frictional force between the welding core and the thick coating is increased, namely adhesive force between the welding core and the thick coating is increased, and use for welding and effects are ensured.

Description

technical field [0001] The invention relates to an electrode, in particular to a thick-coated electrode. Background technique [0002] The welding rod is a metal strip that is melted and filled at the joint of the welding workpiece during gas welding or electric welding, and the welding rod itself applies coating (coating) evenly and centripetally to the welding core outside the metal welding core. The welding core, that is, the metal core, in order to ensure the quality and performance of the weld, its quality is better than that of the base metal; the coating, that is, the coating that is pressure-coated on the surface of the welding core, can make the arc burn stably during the welding process, Weld seam quality is improved. With the continuous development of industrial technology, people have created high-quality thick-coated electrodes that are widely used. Once the thickness of the coating reaches a certain level, the requirements for bonding between the coating and t...
