Received: 17/08/2013 Abstract This paper was aimed to report the 3D finite element analysis simulation of laser welding process of Ti6Al4V 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. The buttjoint welds were made using CO2 laser with the maximum power of 2.2 kW in the continuous wave mode. A part of the experimental work was carried...

Weld bead geometry is a critical factor for determining the quality of welded joints, this welding process input parameters play key role. In study, relationships between variables and size weld produced by pulsed GMAW were investigated neural network trained with Bayesian-Regulation Back Propagation algorithm second degree regression models. A series experiments carried out applying Box-Behnke...

Gas tungsten arc welding (GTAW) is important in those manufacturing where it significant to control the mechanical and metallurgical characteristics its weld bead geometry. This work has been committed study influence of oxide fluxes on 4 mm thick 304 austenitic stainless steel plates. The Al2O3 TiO2 were used as an flux powder form are mixed with acetone. prepared mixture applied plate without...

Numerous GMAW processes have appeared for one-pass welding of medium to high thickness. This concept originated in the 1980s with T.I.M.E. technique and 1990s 2000s saw emergence Rapid Arc, Melt Buried Arc techniques. These did not include any special control features, but rather parameter combinations improve bead geometry. A new interpretation factors that are critical achieving performance (...

In Laser Wire Additive Manufacturing (LWAM), the final geometry is produced using layer-by-layer deposition (beads principle). To achieve good geometrical accuracy in product, proper implementation of bead essential. For this reason, paper focuses on process and proposes a layer (width height) prediction model to improve accuracy. More specifically, machine learning regression algorithm applied...

The objective of this research is to develop an experimental-theoretical analysis about the influence of the cooling medium and the geometry of the welding bead profile in fatigue life and the associated parameters with structural integrity of welded joints. A welded joint with cruciform geometry is considered using SMAW (Shielded Metal ArcWelding), plates in structural steel ASTM A36 HR of 8 m...
