[Case Study 4] Removal of welding discoloration by bright annealing
It has a beautiful finish, and there is no corrosion occurring from the burned areas even when used!
We received a request from an automotive parts manufacturer to improve the quality of their current products, and we would like to introduce a case study that solved the issues with mesh filters. The filter was made of welded wire mesh, but during the welding process, heat caused discoloration and oxidation, resulting in blackened areas. This discoloration not only affected the appearance but also raised concerns that if left unaddressed, corrosion could progress from the burned areas and erode the surrounding material. We proposed the removal of welding burn marks through bright annealing treatment. This successfully eliminated oxidation from the welded areas and maintained the durability and performance of the machinery. [Case Overview] ■ Issues and Requests - Occurrence of welding burn marks leading to black discoloration and oxidation - Concerns about potential erosion of surrounding areas ■ Solution - Proposed removal of welding burn marks through bright annealing treatment - Successfully maintained the durability and performance of the machinery *For more details, please download the PDF or feel free to contact us.
