Surfacing welding electrode

Abstract

The invention relates to the field of surfacing welding electrodes, in particular to a surfacing welding electrode. The surfacing welding electrode comprises a welding electrode skin, a welding core,a connecting block, a connecting groove, a fixing block, a fixing groove, an elastic rubber block, a mounting block, a first clamping groove, a second clamping groove, a sliding groove, a conductive block, a conductive strip, an insulating block and a spring. The surfacing welding electrode is simple in structure and novel in design, the connecting block and the fixing block can be conveniently connected to the surface of the welding core in a sleeving mode, it is guaranteed that the connecting position of the welding core and the welding electrode skin is covered, the situation that the connecting position of the welding core and the welding electrode skin is damaged due to collision is avoided, the use requirement of a user is met, through the effect of an arranged clamping prolonging mechanism, the length of the tail end of the welding electrode can be conveniently prolonged, the welding electrode can be conveniently prolonged after the welding electrode is about to be used, and workers can conveniently use the welding electrode.

Description

technical field [0001] The invention relates to the field of surfacing welding electrodes, in particular to a surfacing welding electrode. Background technique [0002] Overlay welding electrode refers to welding a layer of special alloy surface on any part of the overlay welding workpiece. Its purpose is to improve the wear resistance, corrosion resistance and heat resistance of the working surface, so as to reduce costs and improve comprehensive performance and use. service life; surfacing welding is also commonly used for repairing old and waste; when surfacing welding, electrodes of different alloys and different hardness levels are generally selected according to the requirements of use. [0003] There are many problems in the use of existing electrodes, such as the thickness of the electrode skin at the welding core port of some electrodes is different, and some thinner electrode skins are prone to collide with the welding core, causing partial damage, and the welding ...

AI Technical Summary

Problems solved by technology

[0003] There are many problems in the use of existing electrodes, such as the thickness of the electrode skin at the welding core port of some electrodes is different, and some thinner electrode skins are prone to collide with the welding core, causing partial damage, and the welding rod is shorter. It may affect the user's use, and it is not easy to operate. It is easy to cause damage to the electrodes during the stacking process of electrodes of different lengths.
