Abstract
Welding is one of the most important phenomenon as far as the joining of two bodies are concerned. Welding processes are common in fabrication industries. Different types of welding are used in the automobile industries for the manufacturing of their bodies. Other examples of industries where welding plays a crucial role include construction industries, aviation industries, fabrication of pipelines, general repairing of machines, etc. As welding is such a most important factor in almost all industries, therefore it deserves proper attention in order to optimize the whole welding process. On one hand welding process is quite beneficial but on the other hand, it requires very careful attention of the operator, as there were several cases of accident due to welding just because of the carelessness of the operator. Also, it is a repetitive task so the labor or worker is engaged in working without proper use of their brains and in some other productive works. Thus, a number of manpower is only engaged for welding operation this makes the work boring and this restricts them from showing their true potential. This paper deals with the finite element analysis (FEA) of welded single V joint for obtaining the Shear Elastic Strain, Normal Elastic strain, Strain energy, and Shear stress respectively developed at the welded joint. The temperature of the weld pool taken for analysis is 400°C and the material of the specimen is Mild steel ASTM A 36 for welding and its coordinating filler material AWS A5.1 E 6013 were chosen in this study. The specimen size was 30×150×9mm3 thickness. Welding current was set to 90A with welding speed27mm/sec.
Highlights
An automated system has been developed with the help of an AristoTM robot, so as to have a robotized welding experience and to get the same quality of welding
It is evident from the values and the fig above that the maximum shear stress lies at the edges of the elements and the value corresponds to 2777.4 MPa i.e., in this case, they are the points experiencing the maximum shear stress

Summary
An automated system has been developed with the help of an AristoTM robot, so as to have a robotized welding experience and to get the same quality of welding. After making the assembly part on solid works its IGES format (geometry) is transferred to ANSYS 15.0 for the analysis purpose. The arc temperature is higher as compared to the M.P (melting point) of the work piece and the dropping pattern is sharply on the regions that are away from the weld pool. From the graph i.e., cooling line shown in red colour it is evident that the fall in temperature is very rapid (Linearly) and the regions of the base metal that are away from the weld pool (neighbouring to weld bead) cools quite rapidly. The temperature of HAZ falls very slowly as compared to its neighbouring regions
