Fusion welded Joints in UPVC windows are created by melting and fusing together two or more pieces of metal using high heat and pressure.There are several different types of fusion welded joints, including butt joints, lap joints, and corner joints. Fusion welded joints require specialized equipment and trained personnel to perform the welding process.

In the production of windows and doors, one sort of jointing technology that is utilised is known as fusion welding joints. With the use of this method, two separate pieces of PVC or uPVC (unplasticized polyvinyl chloride) can be joined together to provide a connection that is both smooth and sturdy. The ends of the PVC or uPVC are melted together by a technique called fusion welding, which is a method that combines heat and pressure. After the material has been melted, it is allowed to cool down and solidify, which results in a bond that is both strong and long-lasting. This technique guarantees that the connection is airtight as well as watertight, and it also prevents dust and debris from entering the joint. The fact that fusion-welded joints are extremely sturdy and long-lasting is one of its primary benefits. Because the joints are capable of withstanding a high level of stress and strain and are exceptionally sturdy, they are well suited for usage in openings that are subjected to the elements, such as windows and doors. In addition, fusion-welded joints are resistant to warping and twisting, which are both issues that can arise over time with conventional wooden or vinyl windows. Fusion welded Joints in UPVC windows offer a number of benefits, one of which is that they have an appealing appearance. The joints are almost undetectable, which contributes to the sleek and contemporary appearance of the window or door. This can be of particular use in places where a high level of visual attractiveness is sought, such as in commercial or architectural contexts. This can be very advantageous in these types of environments.
