Abstract

The invention provides a trailing cleaning and weld bead shaping device for Overlaying a branch pipe weld seam. The trailing cleaning and weld bead shaping device comprises a driving component, a transmission component and a shaping and cleaning component, wherein the driving component is movably fixed on a fixed casing and is used for controllably providing a driving force for the transmission component; the transmission component is in driving connection with the driving component and is used for transferring the driving force to the shaping and cleaning component; and the shaping and cleaning component is connected with the transmission component and is used for shaping and / or surface cleaning of a weld bead in an Overlay area. The trailing cleaning and weld bead shaping device providedby the invention has the advantages of simple structure, convenience in application, simple operation and low energy consumption; and the weld seam quality and stress state of an Overlay layer of thebranch pipe weld seam can be effectively improved.

Description

technical field [0001] The invention relates to the field of welding repair, in particular to a device for cleaning with welding and bead shaping for overlay welding of branch pipe welds. Background technique [0002] In the piping design, the branch pipe weld is a common connection method between the main pipe and the branch pipe. Among them, the welding seam structure of the placed pipe seat and branch pipe (example: BOSS head welding seam) is widely used, and its structure and manufacturing process are all mature designs. For small-diameter branch pipe welds, the accessibility of welding and the convenience of interlayer cleaning are poor (especially when the groove angle is too small). When the welding process is not properly controlled, defects such as slag inclusions, lack of fusion, and pores are likely to occur. become a source of failure. Defects in branch pipe welds can be repaired by Overlay surfacing. However, the shape and size of the branch pipe welds are va...
