Laser beam welding has wide acceptability due to least welding distortion, low labour costs and convenient operation. However, laser welding for dissimilar titanium and aluminium alloys is a new area which is having wider applications in aerospace, aircraft, automotive, electronics and other industries. The present study is concerned with welding parameters namely laser power, welding speed, fo...
Penetration control is an important factor in determining the weld quality keyhole mode laser welding, which enables deep penetration. In this study, machine learning models and neural network were developed by using 380 published welding data constructed for steel base metals under following conditions: a power of 0.3-16.7 kW, speed 0.3-20.0 m/min, bead diameter 0.05-0.78 mm. A model SVM (supp...
Observation of the weld pool provides an effective path to understand and control the welding process. Observation data also attribute to the validation of numerical models, which helps researchers to analyze and evaluate the welding process. Extensive research has been conducted to provide in situ monitoring of the weld pool. The arc sensor was one of the first few sensors that was adopted for...
To successfully control the welding process and to make it appropriate for solid freeform fabrication (SFF), it is necessary to fully understand the influence of the welding parameters and the geometry of the substrate on the resulting weld bead dimensions. Extensive experiments with different welding parameters and complex geometrical features such as edges and corners have been designed and c...
Tungsten Inert Gas welding (TIG) process is an important component in many industrial operations. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the influence of welding parameters like welding current, welding speed on strength of low carbon steel on AA1050 material during welding. A plan of experiments bas...
Studies in the field of environmental epidemiology indicate that for the adverse effect of inhaled particles not only particle mass is crucial but also particle size is. Ultrafine particles with diameters below 100 nm are of special interest since these particles have high surface area to mass ratio and have properties which differ from those of larger particles. In this paper, particle size di...
