Some Study Of Submerged Arc Welding – A Review

Abstract

Welding is the process joining two or more similar or dissimilar metal by the application of heat or sometimes pressure. called submerged arc welding process. The main objective of this review paper is to study and understand the various components, equiptments used and the effect of process variables such as welding current, welding speed, electrode, electrode angle etc that direct influences the tensile strength, hardness, bead width, bead reinforcement, depth of penetration etc. Welding is a fabrication or sculptural process which sole purpose is to join the materials. In current era of technology without welding technique we will reach to a stone age. So welding is one of the most useful fabrication process and it is the backbone of industries like construction industries, railways industries, aircraft industries etc. SAW which is

Optimization of TIG welding process parameters on 304 austenitic stainless steel sheet metal using fuzzy logic based Taguchi method

“…The fuzzy logic is a form of expert system for determining the optimal values from a set of input and output variables [26]. Generally, fuzzy controller consists of four modules [12].…”

“…Salah satu jenis proses pengelasan adalah las TIG atau GTAW. Pentingnya pengelasan ini dijelaskan oleh Shah (Shah, 2017), Vyas (Vyas, 2017), Tehami (Tehami, 2020) dan secara lebih komprehensif oleh Devakumar (Devakumar, 2014) dalam makalahnya. Proses pengelasan TIG dapat menyebabkan perubahan-perubahan pada logam, diantaranya adalah perubahan struktur mikro dan perubahan sifat mekanis.…”
