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. ...

This paper proposes a novel Lamb wave line sensing technique for crack detection in a welded stiffener. The proposed technique overcomes one of the biggest technical challenges of Lamb wave crack detection for real structure applications: crack-induced Lamb waves are often mixed with multiple reflections from complex waveguides. In particular, crack detection in a welded joint, one of the struc...

In modern industrial applications like automobile manufacturing, shipbuilding, and aircraft construction. Aluminum alloy is employed to obtain a cost favorable, corrosion-resistant, weight optimized body which provides high stiffness. This paper aims find the influence of Process parameters welding current, Filler rod diameter, Gas flow rate on tensile strength TIG welded AA6082 using ER 4047 f...

Many welded structures are fabricated from stainless steels because these have good mechanical properties and corrosion resistance. It is necessary to predict the residual stress after welding in order evaluate performance of joint. In this paper, butt joint AISI 316L steel plates studied. The Metal Inert Gas (MIG) process selected for material. A SYSWELD software based on Finite Element Method...

Abstract The non-destructive full-field non-contact thermographic technique is applied for flaw detection of the welded joints, in real-time and offline configuration. In this paper, a procedure manual arc welding process presented. Surface temperature acquisitions by means an IR camera were performed during 8 specimen both calibration validation numerical model. investigated variables are (man...

Ultrasonic peening treatment (UPT) as a method of severe plastic deformation was used to treat cruciform welded joints of Q345 steel. The application of UPT achieves material surface nanocrystallization of the peening zone, reduces stress concentration, and produces residual compressive stresses at the welded toe. Micro-structure, hardness, stress relief, S-N curve, and the fatigue fracture mec...

The aim of the paper was to examine the influence of repair welded joints on the service life of steam pipelines for over 220 000 hours of service in creep conditions. The research included the study of the microstructure using scanning microscopy, the tests on mechanical properties at room and elevated temperature, determining the nil ductility transition temperature, and short-time creep test...
