Abstract
Abstract
Input parameters of GMAW can vary continuously at any point of time when used in an industrial welding robot and thus have a huge influence at output quality responses of the weld joint. In advent of welding automation, Industrial robots are used by most manufacturers to boost production rate & reduce operational cost. This publication tries to establish an optimum process parameter band for quality weld joint during continuous robot welding. To establish a relationship between both parameters RSM method has been used in an empirical approach. Input parameters of GMAW which are considered for this study are current, wirefeed rate and industrial robot arm speed, and the corresponding output response in form of weld bead geometry which defines the quality of the process. These all-input parameters have different effect on welding quality independent to each other. Stainless steel material (SUS409) has been used as experiment material.
