“…The good correlation obtained among the results calculated by means of the model and the experimental data validates the improved methodology. On the other hand, Damale and Nandurkar [16] conducted a 3-dimensional coupled transient thermal analysis for simulating the arc-welding phenomenon.…”

The mechanical characterization of the engineering materials is always a topic of interest to engineers and researchers. The objective of this work is to study the butt welded joint resilience and toughness by means of the tensile test and the numerical simulation. The specimens were fabricated by welding two plates of AISI 1015 steel with an E6013 electrode. An algorithm of the numerical integration based on the trapezoid method that allowed calculating the resilience and toughness as the area under the stress - strain curve was implemented. The algorithm was validated by comparing the numerical results of the resilience with those obtained by the analytical method. The results show that the resilience and the toughness values computed with the experimental stress - strain curve, they have correspondence with the same values calculated with the numerical simulation.

“…Most of these methods provide pretensions through mechanical or thermal means to compensate for the welding-induced mismatch of the thermal expansion. Damale & Nandurkar (2012) used the applied restraint method for reducing the MMAW developed angular distortion. Chakravarti et al (1990) attempted effectiveness of certain procedures, which involve stretching loads, preheat, different heat inputs and restraints, in reducing angular distortion of bead on panel welds.…”

Distortion is a severe problem in weld products.It depends on various process parameters like plate thickness, current, voltage, type of weld joint and restraints put on. If distortion is not properly dealt during welding then the product may become useless from geometric accuracy point of view. In the present study, a 3-D coupled transient thermal analysis model with auxiliary side heating (parallel heating) is developed to control angular distortion. During analysis, parallel heating flames are placed at several locations from weld line in cross direction. A user defined subroutine is used to apply transient heat source and side heating flames. Element birth and death technique is used to simulate the filler material deposition. One side multipass 'V' butt weld configuration is used for this study. A series of observational tests are done with a special experimental fixture using Manual Metal Arc Welding (MMAW) to validate the proposed FEA model. It is found that the angular distortion has decreased from 2 mm to 0.4 mm with change in side heating distance from 50 to 90 mm from the weld line.
