The invention discloses a welding type sealing telescopic propeller and a welding method thereof. The welding type sealing telescopic propeller comprises an in-cabin part and an underwater part. A cylindrical sealing structure is arranged on the connecting end face and connected to the connecting end face. The underwater part is provided with a base end face, a butt joint hole is formed in the middle of the base end face, the other end of the cylindrical sealing structure is inserted into the butt joint hole, the underwater part is further provided with a butt joint end face, the butt joint end face is connected with the connecting end face through a flange structure, and a gasket is arranged between the butt joint end face and the connecting end face. Through reasonable welding and sealing of different end faces, welding deformation of the two parts is avoided, the sealing quality is ensured, and the technical problems of equipment deformation, water seepage at a lifting shaft seal position, abnormal sound during equipment working, epoxy cracks and other defects caused by factors such as welding deformation and the like when sealing of the full-rotation telescopic propeller is completed through welding are solved.

    本发明公开了一种焊接式密封伸缩推进器及其焊接方法。所述焊接式密封伸缩推进器包括舱内部分和水下部分;所述连接端面上设置有筒形密封结构连接在所述连接端面上;所述水下部分具有基座端面,所述基座端面中部具有对接孔洞,所述筒形密封结构的另一端插入对接孔洞,水下部分还具有对接端面,所述对接端面与所述连接端面通过法兰结构连接,所述对接端面与所述连接端面之间垫有垫圈。通过不同端面的合理焊接和密封,保证两部分不出现焊接变形,确保密封质量,有助于解决焊接完成全回转伸缩推进器密封时,由于焊接变形等因素,导致出现设备变形,升降轴封位置渗水,设备工作时异响,环氧裂纹等缺陷的技术问题。
