Flanges are the major components of nozzles, which are welded to the pipe or other parts of nozzle. There are several types of flanges, based on their working in a pressure vessel.
The most suitable joining of flange to a pipe, is the use of arc welding process. Probably all kinds of arc welding processes are being implemented on flange joining. The processes include; TIG Tungsten inert gas, FCAW flux core arc, MIG/ MAG metal inert or active gas, SMAW (also known as stick welding).
Competitive welders are required to weld these type of joint who are qualified and authorized to do circumferential welding on complicated structures like pipe to flange joint in nozzle. The above picture is about the TIG welding of stainless steel type pipe to flange joint, containing the beautiful welding cups. don’t forget to share it with your friends.
