Abstract

This is a research on studying the effect of current and voltage towards weldment and mechanical properties in welding of carbon steel of plate using Tungsten inert gas welding (TIG). Construction growth rapidly year by year. Welding technique for plate is the one of factor to ensure the quality of joint. In fabrication process, welded joint will be tests to ensure the quality and defect free. The familiar problem happen at plate joint is corrosion, misalignment, erosion, cracking and etc. lead to leakages or explosion Welded joints may be tested either destructively or non-destructively following the acceptance criteria and standards The focus of this project is to detect defect that occur inside the welded butt joint on a carbon steel plate using Non-Destructive Testing Method (NDT) which are Visual Inspection (VI), Magnetic Particle Inspection (MT), dye-penetrant testing (PT) and Ultrasonic Testing (UT). This project also investigate Mechanical properties consists of hardness and bending. The data of the properties can be obtained from several testing procedure which are specifically designed for it. The test that going to be conducted are bending test and hardness test. In this project specimen are develop from carbon steel plate. These specimen will be joint together on butt joint using TIG welding technique. NDT inspection will be carried out to detect all the defect. The result outcome is to come out with the appropriate welding procedure for butt joint plate using TIG welding technique for produce the enhanced quality of weldment.
