The study focused on the standalone TIG and MIG welding combined effect, emphasizing microstructural properties strength of welded joint, especially heat-affected zone. literature revealed that both techniques their combination have full penetration in terms weld, HAZ for TIG-MIG has a larger width comparison with MIG. joints usually demonstrate ductile fracture compared or joints. However, it ...

We define a bidireccional bottom-up parser for Tree Adjoining Grammars (TAG). This parser is a mixture of a defined bidireccional bottom-up parser for TAG and a new parser for Tree Insertion Grammars (TIG) that we present here. We show that the new mixed parser for TAG presents a significative reduction of the theoretical complexity.

Abstract The influence of keyhole TIG (K-TIG) welding parameters on the weld geometry and defects a new nickel-based superalloy VDM Alloy 780 alloy were investigated using statistical design experiment, microstructures heat-affected zone (HAZ) fusion (FZ) K-TIG-welded characterized. No cracks are found in FZ HAZ. Travel speed significantly influences minimum width (Wm), face root excess metal, ...

The beneficial effect of the friction stir processing (FSP) technique for improving properties fabricated additive parts through microstructural refinement and repairing metallurgical defects has shown its ability to be integrated into a hybrid manufacturing system. In present work, conventional GMAW TIG-based processes were further post-processed with process (FSP). case + processed beads, imp...

An asymmetric Abel inversion processing system was developed to establish a method for diagnosing arc plasma that has an elliptical cross section and is non-axisymmetric in the direction perpendicular observation during welding process. This applied tilted tungsten inert gas (TIG) As result, when this intensity distribution due integration, it confirmed relative error near central axis edge lar...
