Abstract
The invention provides a device and a method for testing the shear strength of a titanium alloy laser filler wire welding lap joint, and belongs to the field of mechanical property testing of titanium alloy lap joints. The problem that the shear strength of the titanium alloy laser filler wire welding lap joint is not tested at present is solved. The number of the adjusting and positioning plates is two, the two adjusting and positioning plates are arranged on the two sides of the lap joint respectively, the number of the jaws is two, the two jaws are arranged at the two ends of the lap joint and the two ends of the adjusting and positioning plates respectively, the lap joint and the adjusting and positioning plates are clamped, the jaws are arranged in jaw seats, the jaws are connected with clamping air cylinders, and the clamping air cylinders are connected with the clamping air cylinders. The jaw is clamped through the clamping air cylinder, the clamping air cylinder penetrates through the jaw base and then is connected with the wire column, left-right positioning plates are arranged on the outer sides of the two adjusting positioning plates, and upper-lower positioning plates are arranged on the upper sides and the lower sides of the adjusting positioning plates. The device is mainly used for testing the shear strength of the titanium alloy laser filler wire welding lap joint.
Description
technical field [0001] The invention belongs to the field of testing the mechanical properties of titanium alloy lap joints, in particular to a testing device and a testing method for the shear strength of titanium alloy laser wire-filling welding lap joints. Background technique [0002] Titanium alloy has the advantages of low density, high specific strength, excellent corrosion resistance and fatigue resistance, and is widely used in the fields of naval equipment and shipbuilding industry. For example, the pressure-resistant shells of the "Jiaolong" and "Struggle" deep-sea manned submersibles are all made of titanium alloy. Due to the difficulty in manufacturing and forming titanium alloys, welding has become a necessary processing method. Laser wire-filled welding has many advantages such as low heat input, narrow heat-affected zone, high welding efficiency, and small residual stress and deformation of welded joints. It has been gradually applied in the field of titaniu...
