A Study for Determination of the Thermal Distribution during Welding in T-jointed Metal Plates (ASTM A572)

Welding represents one of the most complex manufacturing processes in terms of number of variables involved and factors contributing to the final output but it is one of the most important operations of the manufacturing industry. The Objective of this paper is to examine and study the variation in the values of temperature which will lead to determination of intensity and severity of the thermal distribution induced in the vicinity of the junction of plates. In the present research work, detailed investigation was done for determination of temperature distribution in four steel specimens confirming to the standard ASTM A572[6] Grade 50 Type 1 welded in T-joint geometry.In this experiment, thermal distribution measurement was performed by placing various thermocouples at predefined position in the vicinity near weld toe to measure and record the variation in the values of temperature. The data was received from these thermocouples was analyzed and processed by the ABAQUS[1] version 6.12 software. This software directly converted the input values of temperature variation into the corresponding thermal distribution values.
