Oxidation in the context of welding specifically refers to the process where metals combine with oxygen. This reaction typically occurs when metals are exposed to atmospheric oxygen, leading to the formation of metal oxides. In welding, oxidation can be detrimental as it may compromise the integrity of the weld and lead to defects such as porosity or weak bonding. Hence, controlling oxidation through appropriate shielding methods or protective atmospheres is crucial for ensuring high-quality welds. Understanding this aspect of oxidation is vital for welders and engineers to maintain the performance and durability of the welded joints.
