Module 1: Design Arc Welding

Course details

Arc welding processes have been widely used in various industries for many years and are still dominant among the various welding processes. This module will introduce particpants to the fundamentals of the most popular arc welding processes, their advantages and limitations, process variables, operational costs, and process applications. Also covered are the basic concepts of the weldability of various engineering materials. Furthermore, the development and trends of advanced arc welding techniques, such as cladding (or overlaying) and hardfacing, will also be introduced. As an important part in this module, case studies will be used to demonstrate the application of process and material knowledge and provide the participants with a thorough understanding of fabrication and repair using arc welding processes.

Why This Course

This module is especially designed to help participants grasp the fundamentals of the arc welding processes and weldability of different materials, as well as various aspects of fabrication and repairs using arc welding processes. This module will cover the design of products, design of welded structures and joints, selection of base and welding filler materials, selection of arc welding processes, and welding fabrication. On successful completion of this module, participants will be equipped to work in the various stages of arc welding fabrication and repair and, more importantly, will be able to optimise the existing arc welding processes by developing and implementing new arc welding techniques.
