In this research project, copper and stainless steel were connected by two laser welding methods: straight seam swing welding. Then, electronic tensile test machine, X-ray diffractometer, scanning electron microscope metallographic used to analyze the properties, macroscopic microscopic structure morphology phase of welded joint. Based on experimental results, we determined that strength joint ...

INVESTIGATING THE EFFECT OF WELDING PASTE CONTAINING GRAPHENE NANOSHEETS ON BONDING PROPERTIES WELDED AISI 304 STAINLESS STEEL PRODUCED BY FLUX-CORED ARC

the aim of this article is study of tool plunge depth (tpd) effects on mechanical properties of friction stir welding of aa1100 aluminium alloy to a441 aisi steel. for this purpose the 0.1, 0.2, 0.4, and 0.6 mm tpd selected and other welding parameters kept constant. the results shows that the frictional heat increases and stir zone grain size decreases with increasing tpd at both base metals. ...

• We investigate residual stresses and their relaxation in welded steel plates. Residual stress relaxations rely on redistribution plastic deformations . The its affect the ratio fatigue loads. does not vary range. This paper presents experimental numerical investigations to determine surface through-thickness welding butt-welded plates under actions. X-ray diffraction measurement validates acc...
