Welding machine for butt joint of sealing strips

The invention relates to the technical field of welding machines, and provides a welding machine for butt joint of sealing strips. The multiple hot-pressing pieces are movably arranged on the rack and each provided with a first hot-pressing groove, a hot-pressing space is defined by the multiple first hot-pressing grooves and used for hot-pressing one end of the sealing strip, and after sliding, the hot-pressing pieces get away from each other or get close to each other and used for opening or closing the hot-pressing space; the plurality of first moving dies are movably arranged on the rack and are respectively provided with a second hot pressing groove; and the second moving dies are movably arranged on the rack, and the first moving dies and the second moving dies are sequentially arranged at intervals and each provided with a third hot pressing groove. By means of the technical scheme, the problem that in the prior art, sealing strips cannot be continuously welded into sealing rings is solved. 本发明涉及焊接机技术领
