AI Technical Summary
In existing technologies, it is impossible to fix three pipes simultaneously during Y-shaped pipe welding, resulting in low welding efficiency and poor welding quality. The heat-affected zone affects material properties and causes cracks, increases thermal expansion and contraction deformation, and affects structural accuracy and stability.
A welding positioning and clamping fixture for steel structure workpieces was designed, comprising a positioning and clamping mechanism, a water flow cooling mechanism, and a welding mechanism. The fixture achieves tight clamping of three pipes through a clamping seat and a hydraulic rod, mitigates the heat-affected zone through the water flow cooling mechanism, and enables automated welding by a robotic arm.
This technology enables the simultaneous welding of three pipes, improving welding efficiency, ensuring welding quality, preventing the heat-affected zone from affecting material properties, and ensuring the precision and stability of the welded structure.
