Zabezpechennia tekhnolohichnoi mitsnosti zvarnykh stykiv obsadnykh trub [Ensuring the technological strength of welded joints of casing pipes]
Аre analyzed casing columns production peculiarities using welding techniques. Specifically planning of experiments was executed to ensure optimal implementation of the process. The feature of feedback was taken as contents of hardening structures in the thermal compound influence area. The results enabled to set mode options that makes it possible to create high-quality weld in the implementation of the two clad layers. Model sample joints in pipe casing were welded.
