Final answer:
Gas tungsten arc welding (GTAW), also known as TIG welding, is recommended for welding stainless steel plates together due to its high-quality and clean weld.
Step-by-step explanation:
When welding stainless steel plates together, the recommended process would be Gas tungsten arc welding (GTAW), also known as TIG welding (Tungsten Inert Gas welding). GTAW uses a tungsten electrode to create an arc between the electrode and the workpiece, while an inert gas such as argon is used to protect the weld area from atmospheric contamination. This process provides a high-quality and clean weld, making it suitable for stainless steel applications.
Gas metal arc welding (GMAW), also known as MIG welding (Metal Inert Gas welding), uses a consumable wire and an inert gas shield for the welding process. Shielded metal arc welding (SMAW), also known as stick welding, uses a flux-coated electrode and a protective flux coating. Flux-cored arc welding (FCAW) is a similar process to GMAW, but it uses a flux-cored wire instead of a solid wire.
