A sleeve pipe for welding rod is connected

The utility model relates to an engineering construction field specifically is a sleeve pipe for welding rod is connected, characterized by, it includes and is equipped with the sand grip on the innerwall of this tubulose body by the tubulose body, the sand grip is followed the length direction total length setting of tubulose body and is centered on the radial evenly distributed of inner wall oftubulose body, the tubulose body, its inner wall diameter is the same with the diameter of welding rod, sets up the sand grip on the inner wall, it highly is 0.3~0.5mm. Before the welding, dock two or two above welding rods with this sleeve pipe, the length that so can make the welding rod satisfies the not welding demand of co -altitude girder. 本实用新型涉及工程施工领域，具体是种用于电焊条连接的套管；其特征是，它包括管状本体，该管状本体的内壁上设有凸条，所述凸条沿管状本体的长度方向全长设置并围绕管状本体的内壁径向均匀分布；所述的管状本体，其内壁直径与电焊条的直径相同，设置在内壁上的凸条，其高度为0.3~0.5mm。在施焊之前，将两根或两根以上焊条用本套管进行对接，如此即可使电焊条的长度满足不同高度大梁的焊接需求。
