Welding of Pipeline to Enhance Strain Performance

A method and apparatus utilized in forming weld joint is described. In the method, a strength weld between two members is formed by a first welding process and a first weld metal. Then, one or more strain welds are formed by depositing a second weld metal adjacent to the strength weld using a second...

Beschreibung
Zusammenfassung:	A method and apparatus utilized in forming weld joint is described. In the method, a strength weld between two members is formed by a first welding process and a first weld metal. Then, one or more strain welds are formed by depositing a second weld metal adjacent to the strength weld using a second welding process. The strain welds are configured to form a weld joint having a specific minimum height and width to handle tensile strain to a specific strain capacity.
