Abstract

Welding is considered today as the standard joining operation in steel construction. Its purpose is to ensure the continuity of the material to be assembled, the quality of which depends on the proper functioning of the welding technique. Penetrant testing is a non-destructive test that consists of implementing investigative techniques to judge "without destruction" the state of the weld joint. The final objective of this work is to develop an opinion on the suitability of the welding joint of different thicknesses. Thus, metal specimens of different thicknesses were inspected. The results obtained show that, for small thicknesses, the defects are minimal and increase considerably, proportionally with an increase in the thickness of the welded parts. This analysis can be a way to facilitate the location of surface defects in order to reduce defects during welding operations.
