1. INTRODUCTION Welding is an essential process across various sectors, particularly in manufacturing and construction industries, where it is primarily used for assembly purposes. It involves creating a permanent bond between two material surfaces by altering specific physical and chemical properties. The techniques and technologies involved in welding are continuously evolving to meet rigorous international safety and precision standards. Additionally, new applications with extreme conditions or unique material limitations necessitate the development and adoption of diverse welding methods.
2. OVERVIEW OF WELDING,
2.1 History of welding, Welding has evolved significantly over the centuries, shaping and being shaped by technological advancements and industrial demands. The journey from primitive methods to modern techniques highlights a remarkable progression driven by the necessity to join materials with strength and durability. Only methods involved rudimentary forms of forge welding, when metals were heated in a fire and hammered together, a technique predominantly used for blacksmiths for centuries [4]. The advent of the industrial revolution marked a pivotal point in welding development. As industries grew and infrastructure demands soared, more sophisticated methods were required, the late 19th and the early 20th century witnessed significant breakthroughs with penetration of gas welding and electric arc welding [5]. These innovations provided more control and precision, enabling the joining of metals for a wide range of industrial applications.
The advancements in welding are also being driven by the demands of industry 4.0 and additive manufacturing, both of which heavily rely on automation and robotics. Industry 4.0 aims to create smart factories with interconnected systems, where welding processes are integrated into automated production lines to enhance efficiency, consistency and quality. Additive manufacturing, which includes 3D printing, requires precise welding techniques to build complex structures layer by layer, often involving materials that present unique challenges. The continuous innovation in welding technologies includes
