Joining of flange to pipe using an arc welding process, is very common in fabrication of pressure vessels, boilers, power plants etc. A Flange is a ring shape structure used to connect pipe with another items. The above picture shows circumferential TIG welding of a pipe to flange joint.
The main objective of a flange joining with a pipe is to strengthen the job assembly or to provide a connection with another items. Flanges are available in different shapes and forms depending on the type of application and service.
Types of Flanges
- Weld Neck Flange
- Socket Weld Flange
- Blind Flange
- Lap joint Flange
- Threaded Flange
- Slip on Flange
Pipe to Flange joint is a major concern for welding point of view and requires great skills. Suitable welding conditions are required in order to avoid distortion in the assembly and to achieve sound welding properties. Another point for flange is that it can be bolted or threaded according to the type of flange to connect with other object. There are several schools which have been serving since a long time to provide quality education on all types of welding. There are many opportunities for future welders in the field of fabrication, welding and brazing industries.
