Abstract

The invention relates to the field of welding materials, in particular to a welding rod. A core wire and a coating are included. The coating wraps the surface of the core wire. The length of the corewire is larger than that of the coating, and the part, extending out of the coating, of the core wire is named as a clamping part. The clamping part is divided into two parts including a core wire body and a clamping body which are detachably connected. After the above structure is adopted, an original integrated core wire is designed into the two parts including the core wire body and the clamping body, the length of the part, extending out of the coating, of the core wire body is reduced, during welding, the welding rod can be combusted to the position where the coating is completely consumed, and waste of a large number of resources due to occurrence of a welding head is avoided. Through two parallel planes of the clamping body, stable welding rod clamping is achieved, and smooth proceeding of welding is guaranteed.

Description

technical field

[0001] The invention relates to the field of welding materials, in particular to a welding rod. Background technique

[0002] Welding rods are consumables that must be used in most cases when welding. Commonly used welding rods are composed of two parts: welding core and coating. The length of the metal welding core will be greater than the length of the coating. When welding, the long section of the metal welding core is clamped on the welding torch to conduct electricity, and then the arc is started for welding. When the welding rod burns to a certain distance close to the clamping part, in order to protect the welding tools and welding workers, the arc is generally selected to be extinguished, so that a large number of welding heads are produced, which seriously wastes resources.

Embodiment Construction

[0011] 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.

[0012] Such as figure 1 As shown, a kind of electrode described in the present invention comprises a welding core 1 and a coating 2, and the coating 2 is coated on the surface of the welding core 1; the length of the welding core 1 is greater than the length of the coating 2, and the welding core 1 The part that grows out of the coating 2 is called the clamping part; the clamping part is composed of two parts, the welding core body 6 and the clamping body 5, wherein the welding core body 6 and the clamping body 5 are detachably connected. Before welding, the welding core body 6 is installed on the ...
