Abstract

This solution discloses a welding device, comprising: a box body; an air inlet and an air outlet arranged on the box body; at least one opening arranged on the box body is used to put in the parts to be welded, or take out the welding to complete Parts; the guide part arranged inside the box, when the protective gas is passed into the inside of the box through the air inlet, the guide part moves from the air inlet to the air outlet, and the air in the box Exhausted from the air outlet; and, the welded portion provided below the deflector. This solution can effectively remove the air in the box by setting the diversion part, so that the box can be filled with sufficient protective gas, and its concentration can be guaranteed, so as to avoid the rework of the titanium alloy pipe-flange due to insufficient protection of the welding protective gas. Or the risk of scrapping raw materials.

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...
