Abstract

Disclosed is an adjustable reverse-deformation welding jig for titanium alloy. The adjustable reverse-deformation welding jig for titanium alloy comprises a base and a clamping platform, wherein the clamping platform is located on the base. A first square groove is formed in the middle of the clamping platform, a reverse side gasket is fixedly arranged in the first square groove, and reverse deformation cushion strips are placed on the two sides of the reverse side gasket. A titanium alloy test plate is placed on the clamping platform, and a left press plate and a right press plate are placed on the titanium alloy test plate. Rapid clamps are installed on the clamping platform and tightly press the titanium alloy test plate by tightly pressing the left press plate and the right press plate. The reverse side gasket, an air pipe, the reverse deformation cushion strips, the left press plate and the right press plate are made of materials easy to achieve heat dissipation. The adjustable reverse-deformation welding jig for titanium alloy can provide reverse side protection in the process of titanium alloy welding, ensure the forming quality of the reverse side, and effectively reduce welding deformation.

Description

technical field [0001] The invention relates to a welding fixture used for adjustable anti-deformation of titanium alloy, which belongs to the field of welding. Background technique [0002] Titanium and its alloys have excellent corrosion resistance, low density, high specific strength, good toughness and weldability, and are widely used in aviation, aerospace, shipbuilding, chemical and other industrial sectors. As an important technical means in titanium alloy processing, welding has unique advantages in improving material utilization, reducing structural weight, and reducing costs. Therefore, research work on titanium alloy welding has been valued by welding workers at home and abroad. The main welding methods of titanium and titanium alloys are argon tungsten arc welding, argon metal arc welding, plasma arc welding, electron beam welding, laser welding, diffusion welding, etc. At present, argon tungsten arc welding is most widely used in the welding of titanium alloy ...
