Final answer:
Welding processes are identified by the American Welding Society using a specific coding system that classifies methods and materials. Welding itself joins metals by melting them together, with various techniques such as gas, electric, and laser welding. The AWS system standardizes the industry language to facilitate clear communication.
Step-by-step explanation:
The American Welding Society (AWS) has established a coding system to identify different welding processes. This coding system helps in classifying the various types of welding based on the method used and the nature of the solder and fuel. Welding itself is a fabrication process that joins materials, typically metals, by using high heat to melt the parts together and allowing them to cool, causing fusion. Processes such as gas welding, electric arc welding, and laser welding are identified with specific AWS codes to standardize communication within the industry.
Welding has been an integral part of metalworking since its inception, with forge welding being one of the oldest known techniques used by blacksmiths for joining iron and steel. Modern welding techniques can utilize a variety of energy sources including gas, electricity, and lasers. For example, the thermite reaction is a type of chemical welding that uses aluminum metal and iron(III) oxide to produce molten iron, which can then be used to join metal parts.
Organizations like the International Association of Machinists and Aerospace Workers and the United Automobile, Aerospace and Agricultural Implement Workers of America (UAW) are significant stakeholders in the industry that represent the interests of professionals who rely on and uphold AWS standards.
