Deformation and looseness caused by welding defects

The welding process of aluminum profiles is an important step in ensuring the structural stability of windows. If defects occur during the welding process, such as a weak weld, the window may become deformed or loose during use. This not only affects the appearance of the windows, but may also cause safety hazards. Therefore, manufacturers must strictly control the process when welding aluminum profiles to ensure the safety and reliability of windows.
