دراسة توغل الفطر و الفشل في لحام الصلب المقاوم للصدأ

الملخص EN

The rate of resistance to the penetration of the stress fungus was studied for several samples in which welding is on different dimensions from a welded sample at a distance of 5 mm to a welded sample at a distance of 25 mm, with a difference of 5 mm for each sample.

The highest resistance to the penetration rate of the fungus was observed in the sample in which the weld is at a distance of 25 mm, while the resistance decreases near the thermally affected areas in the welded samples at a distance of 5 mm and 10 mm.

It was also observed that the compressive residual stresses hinder the penetration of the fungus into the samples containing small-scale welding defects, and this effect is absent in the presence of large-scale welding defects.
