UOW Assignment 1: Welding Processes and Distortion Analysis

This assignment solution addresses welding processes and distortion, focusing on the context of dragline excavators used in opencast mining. The first part compares GTAW and GMAW welding, evaluating their suitability for carbon steel pipes, considering factors like tungsten inclusion, welding time, and electrode size. The second part delves into fusion welding, explaining the causes and types of distortion (transverse, longitudinal, angular, etc.), and methods to minimize it, such as preventing over-welding, using intermittent welding, and limiting the number of welds. The solution emphasizes the impact of distortion on the performance of welded metals and the importance of selecting appropriate welding techniques to maintain material strength and durability.
