Abstract AR
في هذا البحث، تم اختبار الصلب للصدأ (316) لهذا الدراسة و اختباره لإيحاد تركيبه الكيميائي و خواصه الميكانيكية و أزالة الإجهاد.
حيث تم أولا "لحام صفيحتين ذات أبعاد (55x55x1) ملم باللحام النقطي و بعدها اختبار بجهاز حيود الأشعة السينية (XRD) لقياس اجهادات الشد المتبقية بسبب التأثير الحراري الناتج من عملية اللحام.
لغرض إزالة إجهادات الشد المتبقية، أجريت عملية السفع بالكريات للصفائح الملحومة بلحام النقطة لتوليد إجهادات متبقية انضغاطية و التي ستحسن من عمر الجزء الملحوم بلحام النقطة خلال استخدامه.
و أظهرت نتائج قياس حيود الأشعة السينية تكوين الإجهادات المتبقية الانضغاطية فقط في الصفائح الملحومة نقطيا " التي تم سفعها كرويا ".
Abstract EN
In this paper, a stainless steel 316 was selected for this study and tested to obtain its chemical composition, mechanical properties and stress relieving.
Then, two plates (55 * 55 * 1) mm were first joined by spot welding and later tested by X-Ray diffraction (XRD) machine to measure the tensile residual stresses formed due to thermal effect.
In order to remove the tensile residual stresses, a shot peening process for these spot welded plates was made to create the compressive residual stresses which will improve the life of spot welded part during the service.
The results of the x-ray diffraction tests exhibited that only compressive residual stresses formed in the shot peened spot welded plates.
