Description

[0002] Welding jigs are mainly used to fix and position the workpieces to be welded, ensuring the stability and accuracy of the workpieces during the welding process. With the continuous expansion of the aluminum alloy door and window market and the improvement of consumer requirements for product quality, door and window manufacturing companies are facing multiple pressures such as improving production efficiency, reducing costs and ensuring product quality. Aluminum alloy materials have the characteristics of light weight, beauty, and corrosion resistance, so they are widely used in door and window manufacturing. However, aluminum alloys have fast thermal conductivity and are prone to thermal deformation during welding, which places high requirements on the welding process. In order to ensure welding quality and stability, welding jigs are needed to fix and position aluminum alloy door and window workpieces to reduce deformation and deviation during welding.
