Beschreibung
Zusammenfassung:	A portion of a submerged combustion burner is disposed into a pressure vessel. The portion of the submerged combustion burner has a welded area that has a first microstructure defined by a first number of voids. The vessel is filled with an inert gas, pressurized, and heated. Pressurizing and heating operations are performed for a time and at a temperature and a pressure sufficient to produce a second microstructure in the welded area of the burner. The second microstructure is defined by a second number of voids less than the first number of voids.
