Laser welding is one of the important welding processes in industries for joining similar or different metals. Demand of dissimilar metal welding has increased now a days from high performance, cost saving and efficiency point of view. Various parameters like speed, beam power, spot diameter affect the quality, strength and cost of welding process. In this paper the influence of speed, beam power and spot diameter over strength of welded specimen is studied using Taguchi orthogonal array method. Two dissimilar metals such as 61Ni-21Cr-9M o alloy and 99.3Fe-0.45M n-0.2C steel is welded using laser beam. The experiments are carried out as per Taguchi orthogonal array design matrix to predict optimum process parameters Analysis of variance (ANOVA) is carried out to determine significantly affecting parameter and the mathematical model to estimate ultimate tensile strength has been developed using Regression method. The simulation of welding process to predict temperature distribution and residual stresses is predicted.

Civil structure is typically large-scale and it is complex in behavior and they create huge impact in modernized nations. Assessment of a structure’s integrity is a challenging task. Studying and implementing structural health monitoring technique is becoming essential to predict the deformation in the structural components which may cause tremendous loss to human life as well as to economy. The prime objective of our proposal is to use sensors to incessantly keep an eye on the buildings and to build a warning system for the consumers prior to damage through Global System for Mobile communication (GSM). Prototype resembling the structural components like beam, column, etc. can be monitored by using various sensors like load cell, accelerometer and vibration sensor. The monocratic function of the Structural Health Monitoring (SHM) system involves detection of changes in the structures by sensors and it transmits the signal to the controller which ensures the threshold of the incoming signal. Real-time variation in magnitudes of loads, inclination and vibration are sent as SMS to users through GSM. Further physical phenomenon of structures can be monitored by using various sensors which guarantees the existing structure a smart one.
