A clean work environment is vital for producing high-quality welding beads. Contaminants such as oil, rust, and dirt can compromise the weld, leading to defects like porosity and inclusions.Proper cleaning of the workpieces before welding ensures a stronger bond and better bead appearance. 5) Uti...
This chapter provides an overview of the common types of defects found in various structural materials and joints in aircraft. Materials manufacturing methods (including large-scale production) have been established in the aircraft industry. However, as will be seen in this chapter, manufacturing defec...

Radiographic testing is a well-established non-destructive testing method to detect subsurface welding defects. In this paper, an automatic computer-aided identification system was implemented to recognize different types of welding defects in radiographic images. Image-processing techniques such as back...
