Abstract |
This paper describes the results of the authors’s experimental research regarding the WIG butt-welding procedure (WIG – Wolfram Inert Gas) applied to a number of A and QT 700 (X 70) specimens of coiled tubing under laboratory conditions (QT = Quality Tubing; 700 = 70,000 psi = 482.58 N/mm2 as their yield strength), the two possible options (presence or absence of a permanent metal support of the root) being equally taken into account and the results of the non-destructive tests (penetrating radiation testing) as well as those of the destructive ones (tensile / flattening / hardness tests and microscopic examination) applied to the coiled tubing in its position of oilfield tubular materials.
