STUDY, MONITORING AND IDENTIFICATION ASSESSMENT ON WELDING

A welding joint is a point or a rim that connects two or more pieces of metal or plastic. This consists of welding certain geometry between two or more pieces of work (metal or plastic). In the world today these joints have a central role across building and machine components and the reliability of these joints and welding determines the existence of these devices, keeping them from losing whether they include loss of human beings, financial losses or damages. These joints are very important in terms of the quality of their joints. In this article the identification methods or tools for soil defects such as inside and outside fractures, inadequate fusion, lack of insight, blow holes, inclusion of slacks and deformation etc. Soldering defects are detected and monitored. Many approaches or techniques are also briefly explained to detect welding defects. Weld-ability of a material depends upon different factors like said metallurgical changes that occurs due to welding, extent of oxidation etc. If filler material used is same of the base material then it is homogeneous welding otherwise its heterogeneous
