Welding is one of the most successful applications for industrial robots, which encourages intensive research and development in the area of the CAD-based and off-line programming (Pires et al., 2003, Yagi, 2004). At present, relevant software tools allow to optimise the process parameters, which directly influence the product quality and the system working cycle. Besides, they enable users to ...

The paper presents the results of experimental studies strength cross-shaped welded joints types К1-Кт and К3-Рр [1] thermomechanically hardened reinforcement class A500C [2] for hardening during welding main bar [3].
 Experimental included testing three series samples in initial state. first type to strengthen welding. Reinforcement Ø14A500С was accepted as (working) bar, Ø12A500С Ø8A240С...

Friction stir welding (FSW) is a relatively new welding process that may have significant advantages compared to the fusion processes as follow: joining of conventionally non-fusion weldable alloys, reduced distortion and improved mechanical properties of weldable alloys joints due to the pure solid-state joining of metals. In this paper, a three-dimensional model based on finite element analys...

Neutron diffraction measurements have been performed to determine the full residual stress tensor along the expected crack path in an austenitic stainless steel (Esshete 1250) compact tension weld specimen. A destructive slitting method was then implemented on the same specimen to measure the stress intensity factor profile associated with the residual stress field as a function of crack length...

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...

Abstract In this paper, the effect of autogenous diode laser beam welding (LBW) and influence post weld heat treatment (PWHT) on microstructural changes mechanical properties dual phase DP1400 high strength steel (HSS) butt welded joint are studied presented. LBW PWHT were performed 1 mm sheet thickness using 3 5 kW systems, respectively. The technology ensures quality joints in HSS facilitate ...
