During a welding process, small metal spatters often detach from the fusion zone. These solidified particles on the surface are called **welding scrapings or welding residues**. They can: - stick around the weld bead, - accumulate on equipment, - or remain trapped in parts. Although sometimes tiny in size, these residues can impair the aesthetic, mechanical, and functional quality of assemblies. ## FAQ What is a welding scrape? A weld scrape is a small metal projection from the fusion zone during a welding process. Once solidified, it remains attached to or around the part, potentially affecting its mechanical, aesthetic, or functional quality. Why analyze welding scrapings and residues? Analysis helps to understand their composition and origin, to assess their impact on the welded part and to optimize welding parameters. It is essential to ensure that parts comply with industrial specifications. What problems can welding scrapings cause? They can cause aesthetic defects, promote corrosion, disrupt assembly, reduce the life of parts and lead to non-conformities during quality controls. Who needs this type of analysis? Manufacturers in demanding sectors such as aeronautics, automotive, energy, medical, space or defense, as well as R&D teams. Can the FILAB laboratory help improve welding processes? Yes. Beyond analysis, our experts work with your teams to interpret the results and suggest areas for improvement to limit the appearance of scuffs and optimize your processes.
