Several international standards and norms apply to welding processes and the structure and features of welding machines and supplies. They contain definitions, instructions and restrictions for procedures and machine structures to increase the safety of processes and machines and to ensure the quality of products.

For example, the general standard for arc welding machines is IEC 60974-1 while the technical terms of delivery and product forms, dimensions, tolerances and labels are contained in the standard SFS-EN 759.
