TY - JOUR AU - Andrzej Klimpel PY - 2024 DA - 2024/03/15 TI - The Physical and Technological Background of the GMA Process JO - Japan Journal of Research VL - 5 IS - 2 AB - Gas Metal Arc (GMA) welding is widely used in the world manufacturing industry of modern metal structures, such as buildings, bridges, yellow goods, thanks, pressure vessels, piping, pipelines, etc., ensuring high-efficiency and high-quality semiautomatic, automatic and robotic welding. This paper describes the basic physical and technological backgrounds of GMA welding process and provides comprehensive analysis of the influence of basic GMA welding parameters on efficiency of welding and the quality of welded joints. Examples of GMA welding applications are given. SN - 2690-8077 UR - https://dx.doi.org/10.33425/2690-8077.1106 DO - 10.33425/2690-8077.1106
