Abstract

The invention discloses a gas-saving protection device for argon arc welding bottoming of power station piping, which includes a gas guiding structure, a sealing structure and a connecting ring. The sealing structure includes ring structures respectively located at two ends of the connecting ring. There is a gas-filled cavity between the outer walls of the connecting ring, and the gas-guiding structure includes an air-guiding tube and an air-intake tube connected together. The gas-guiding tube is ring-shaped, sleeved outside the connecting ring, and located in the gas-filled cavity , there are several air outlet holes distributed on the air guide tube. The gas-saving protective device for argon arc welding bottoming of power station pipes of the invention is an energy-saving device that can save argon, save time, reduce labor intensity, and improve efficiency.

Description

technical field [0001] The invention relates to the technical field of welding auxiliary equipment manufacturing, in particular to a bottoming and gas-saving protection device for argon arc welding of power station piping. Background technique [0002] At present, the welding of power station piping basically adopts the welding method of argon arc welding for bottoming, arc welding or submerged arc welding for filling and covering. When welding the argon arc welding backing in the factory, the traditional protection method is to carefully paste and seal the multiple ports, openings and gaps of the welding piping with adhesive tape to make an argon chamber, and then fill it with argon to replace the air, and wait It takes 30 to 60 minutes, and the argon decompression meter is opened to a maximum flow rate of about 25 to 30L / min. Welding can only be performed after the gas chamber is completely filled with argon. Especially for piping with a diameter greater than 700mm, a lot...
