Weld blocks are typically used in UPVC window fabrication machines to hold the frame components in place during the welding process. If weld blocks are not used or are improperly positioned, several issues can occur:

Misalignment: Without weld blocks, the frame components may not align correctly during welding. This can result in uneven or crooked joints, affecting the window’s aesthetics and functionality.
Weak Joints: Inadequate support from weld blocks can lead to weak and unreliable weld joints. Weak joints may compromise the window’s structural integrity, reducing its durability and resistance to environmental factors.
Welding Defects: The absence of weld blocks can cause welding defects such as gaps, voids, or incomplete welds. These defects can create air or water leaks in the finished window, reducing its efficiency and performance.
Increased Scrap: Improper welding due to the absence of weld blocks can result in a higher rate of rejected or scrapped window frames, increasing production costs.
In summary, using weld blocks is essential in uPVC window fabrication to ensure precise alignment, strong weld joints, and high-quality finished products. Failure to use them can lead to various issues in window construction.
