Stainless tube may be joined by any methods EXCEPT which of the following?

Explanation:
Joining stainless steel tubing for piping relies on creating a metallurgical bond that yields a strong, leak-tight joint. Soldering uses a filler metal that melts at a low temperature and does not fuse the base metals, so the joint isn’t strong enough or corrosion-resistant enough for stainless steel piping under pressure. That’s why soldering is not used for stainless tube joins. The other methods listed—TIG (which is the same as GTAW) and MIG (GMAW)—are welding processes that fuse the metals to form solid, durable joints suitable for stainless steel tubing. TIG/GTAW offers precise, clean welds, while MIG/GMAW allows faster production; both provide the necessary strength and leak integrity.
