Abstract

The invention provides a titanium alloy laser arc hybrid welding 45-degree welding gun welding gas protection dragging cover. The dragging cover comprises a dragging cover body, a gas sieve plate, a gas outlet plate, a gas inlet connecting pipe, a connecting clamp and a semicircular fixing seat, the dragging cover body comprises a top plate, a 45-degree fixing seat and a rear plate, the gas sieve plate is arranged in the dragging cover body, the gas outlet plate is arranged below the gas sieve plate, the gas inlet connecting pipe comprises a gas inlet pipe body and a sleeve shaft, and the connecting clamp comprises a connecting plate, a connecting clamp body and a fixing clamp. By means of the dragging cover, high-purity argon can be effectively and evenly injected into the titanium alloy welding surface, a titanium alloy welding seam is isolated from air, the gas protection problem during butt welding of titanium alloy laser-arc hybrid welding flat plates can be solved, a welding area is thoroughly protected, and the performance quality of a welding joint is improved.

Description

technical field [0001] The invention belongs to the technical field of welding gas protection, and in particular relates to a 45-degree welding torch welding gas protection drag cover for titanium alloy laser arc hybrid welding. Background technique [0002] Since titanium and titanium alloys have a strong affinity for oxygen, nitrogen, hydrogen and other gases in the air, good protection measures must be taken in the welding area to ensure that the welding pool and the front and back sides of the heat-affected zone with a temperature exceeding 350 °C Keep away from air. Unprotected titanium absorbs hydrogen above 300°C, oxygen above 600°C, and nitrogen above 700°C. These gases will cause joint embrittlement after being absorbed by titanium. Inhalation caused by poor protection, metastable structure caused by rapid cooling of weld seam and heat-affected zone, alloy type and other factors all affect the welding performance of titanium and titanium alloys.
