Problems solved by technology

[0003] The welding of the stiffening ring of the large-diameter pressure steel pipe is usually carried out by manual welding. The workload of the welding personnel is large and the work efficiency is low. Moreover, the welding quality cannot be guaranteed during the manual welding process. It is prone to welding deformation, which affects the quality of the entire penstock; the welding cost is relatively high during the welding process
[0004] The previous application "An automatic welding device and method for penstock stiffening rings" also disclosed a welding device for penstock stiffening rings, but this welding device can only be applied to the welding of small diameter penstocks A horizontal structure is required in the process, and an auxiliary device is required to flip the steel pipe

Abstract

The invention discloses a reinforcing ring automated welding system and method suitable for pressure steel pipes. The system comprises a welder which is connected with an externally-connected power source through an externally-connected power source wire, the welder is connected with an opening valve of an air bottle through a welder low voltage output wire, an outlet of the air bottle is in matched connection with a welding gun of a welding trolley through an output air pipe, the welder is connected with the welding gun of the welding trolley, the welding gun of the welding trolley is matched with a wire feeder to realize automatic wire feeding, the wire feeder is connected with a welding wire winding drum, and the welding trolley is connected with a trolley externally-connected power source through a trolley externally-connected power source wire. By the system, manufacturing quality of large and huge pressure steel pipes can be improved, automated welding of reinforcing rings can be realized, productive forces can be emancipated, production efficiency can be improved, and production cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of automatic welding of penstock steel pipes, and in particular relates to an automatic welding system, a welding trolley device, and a welding method and method suitable for penstock steel pipe stiffening rings. After the stiffening ring is assembled, the automatic welding device for flat fillet welding formed by the stiffening ring and the steel pipe wall can also be used for welding flat fillet welds of external accessories such as large drum-shaped containers. Background technique [0002] The penstock is an important part of the water delivery structure of the hydropower station. It connects the water inlet of the power station and the volute of the turbine, and plays the role of introducing water from the water inlet into the volute to propel the turbine to rotate. The common layout forms of penstocks are: exposed pipes, underground pipes, backfill pipes, back pipes behind dams, buried pipes behind dam...
