An investigation on girth friction welding of duplex stainless steel pipes

Journal of Manufacturing Processes, 2020
Girth friction welding is a novel technique to join co-axial linepipes with an external ring (girth) in solid state and without melting of materials. The ring or the girth is rotated between two pipes under an axial force resulting in frictional heat ...

Connectivity of graphs with given girth pair [PDF]

Discrete Mathematics, 2007
Girth pairs were introduced by Harary and Kovács [Regular graphs with given girth pair, J. Graph Theory 7 (1983) 209–218]. The odd girth (even girth) of a graph is the length of a shortest odd (even) cycle.

Experimental and numerical analysis of non-contact magnetic detecting signal of girth welds on steel pipelines.

ISA transactions, 2021
The quality of the girth welds on pipelines is a critical point regarding the safe operation. Non-contact pipeline magnetic detection (NPMD) is a non-destructive detection technology based on the metal magnetic memory (MMM) method.

Fast Distributed Algorithms for Girth, Cycles and Small Subgraphs

International Symposium on Distributed Computing, 2021
In this paper we give fast distributed graph algorithms for detecting and listing small subgraphs, and for computing or approximating the girth. Our algorithms improve upon the state of the art by polynomial factors, and for girth, we obtain an constant ...
