Electrode cap

The utility model provides an electrode cap, and relates to the technical field of welding. The electrode cap comprises a contact end, a transition section and an interface end which are connected insequence, wherein the contact end, the transition section and the interface end are integrally formed; wherein the interface end is formed into a cylinder, the contact end is formed into a quadrangleon the cross section perpendicular to the axis direction of the interface end, and the cross section area of the contact end is smaller than that of the interface end. According to the technical scheme, through the redesigned electrode cap, narrow spaces such as a car door sealing strip guide rail can be welded, the electrode cap is suitable for most of welding equipment, and the welding feasibility and practicability are guaranteed. 本实用新型提供了一种电极帽，涉及焊接技术领域。该电极帽包括：依次连接的接触端、过渡段以及接口端，且所述接触端、所述过渡段以及所述接口端一体成型；其中，所述接口端形成为圆柱体，在垂直于所述接口端的轴心线方向的横截面上，所述接触端形成为四边形，且所述接触端的横截面面积小于所述接口端的横截面面积。本实用新型所提供的技术方案，通过重新设计的电极帽，可对车门密封条导轨等狭窄空间进行焊
