Abstract

The invention relates to automatic bead welding equipment of a saddle-shaped pipe joint surface with a conical table and a welding method thereof, belonging to the technical field of automatic welding equipment and welding methods. The equipment comprises a station regulating device, an automatic welding gun manipulator, a laser positioner and an electrical control device. When the equipment works, the electrical control device controls the station regulating device and the automatic welding gun manipulator to be dynamically matched to complete the bead welding of an anti-corrosive layer of the saddle-shaped pipe joint surface with the conical table. The invention has the advantages that the electrical control device controls five-shaft linkage so that the end surface of the bead welding position of a workpiece is in a horizontal state; due to the adoption of a hot wire TIG (Tungsten Inert Gas) welding process and a horizontal continuous welding, the automatic bead welding equipment has good welding quality; the automatic bead welding equipment completely realizes automatic welding, reduces the polishing quantity of the bead welding surface and improves the utilization rate of a welding material; and voltage is added between a wire-feeding conducting nozzle and the workpiece through adopting a hot wire technique so that current flows through a welding wire between the wire-feeding conducting nozzle and the workpiece to heat the welding wire, and then the absorption of the welding wire for the heat quantity of an electric arc is reduced, thereby improving the welding efficiency.

Description

technical field

[0001] The invention relates to an automatic surfacing welding equipment and welding method for the saddle-shaped pipe joint surface with a conical truncated pipe, and is especially suitable for the saddle-shaped pipe end surface formed by intersecting main pipes and branch pipes of different diameters and the joint surface with a conical truncated pipe on the end surface. The anticorrosion layer surfacing welding belongs to the technical field of automatic welding equipment and welding methods. Background technique

[0002] The saddle-shaped pipe joint with conical frustum is a commonly used pipe joint in the petrochemical and electric power industry. An externally sloping conical step with different full-circle widths at the end and sides. If the pipe joint has a round end face, it can usually be automatically welded by submerged arc automatic welding, gas shielded welding or TIG welding. When the height of the saddle-shaped end face changes greatly and t...
