Abstract

The invention discloses a welding device. The welding device comprises a box, an air inlet, an air outlet, at least one opening, a flow-guiding part and a welding part, wherein the air inlet and the air outlet are formed in the box; the at least one opening is formed in the box, and the openings are used for placing parts to be welded or taking welded parts out; the flow-guiding part is arranged in the box, under the condition of pumping protective gas into the box through the air inlet, the flow-guiding part moves from the air inlet to the air outlet, and air in the box is discharged from theair outlet; and the welding part is arranged below the flow-guiding part. By arranging the flow-guiding part, the air in the box can be effectively discharged, so that the box is full of the sufficient protective gas, the concentration of the protective gas is ensured, and thus the risk of rework or raw material scrapping due to the fact that the protective gas welding protection is not in placeof a titanium alloy pipe-flange is avoided.

Description

technical field [0001] The proposal relates to the field of equipment processing and manufacturing, and specifically relates to a device for welding titanium alloy pipes and flanges in the shipbuilding industry. Background technique [0002] Titanium alloy pipes are often used in system piping in extremely harsh environments such as ship high pressure and seawater corrosion resistance. Titanium alloy pipe-pipe and titanium alloy pipe-flange welding have always been the most difficult to control in the manufacturing process of ship titanium alloy piping systems. one of the processes. The color of the welded joint and its surrounding base material directly affects the quality of the pipeline system, such as the omission of the quality of the weld seam inspection, even directly affects the safety and service life of the ship. [0003] At present, for titanium alloy pipe-pipe and titanium alloy pipe-flange welding, the molten pool area is generally protected by inert gas spraye...
