1results about How to "Eliminate Welding Defects" patented technology

This invention relates to the field of welding-related technologies, and in particular to a welding device for processing metal back panels of television sets. The device includes a welding box, a fixed frame, and a welding rack. The fixed frame is fixedly mounted on the top of the welding box, and the welding rack is movably mounted on the bottom of the fixed frame. A pushing welding assembly is installed inside the welding rack, which pushes the welding torch head within the assembly to move horizontally across the back panel surface, forming a continuous welding strip. The tilting lateral assembly of this invention achieves digital and programmable angle adjustment, with high precision and good repeatability, enabling it to perform automated welding of various complex welds such as flat fillet welds and vertical fillet welds. The single-point pressure assembly refines grains and releases thermal stress through mechanical impact, directly intervening in welding deformation and cold cracking hazards. The downward cleaning assembly ensures that every welding is performed on a contaminated surface, fundamentally eliminating welding defects such as porosity and slag inclusions caused by dust and oil.
