The invention discloses a fabrication process of a gas pipeline and a welding device for sealing the end of a gas pipeline. The welding device has the beneficial effects that outer walls of two end openings of the gas pipelines are bent towards the center of the gas pipeline through cams and wedge press plates on an edge folding device to form flat openings; during welding, opening sealing is achieved by only welding one edge, and a rectangular iron plate is not needed to be additionally fabricated; square pipe opening welding saves the use of steel materials, and quickens the welding speed; the gas pipeline is pushed to the welding device by a push plate, opening sealing is carried out by welding guns which are arranged on two sides of the opening of the gas pipeline and move in a reciprocating manner; automatic material push, welding and discharge are integrated; efficiency is high; and the labor intensity is low. 本发明公开了种气路管制作工艺及气路管端部封闭的焊接装置，本发明的有益效果在于：通过折边装置上的凸轮和楔形压板将气路管两端开口的外壁均向气路管的中心折弯形成扁形开口、焊接时只需焊接边即可进行
