Abstract
Welding of collector pipes, flat heads, dished ends and connector pipes performed with high temperature and creep-resisting steels most often has been done by combination of 141 (TIG) and 111 (MMA) processes. In most cases, it is required to carry out Post-Weld Heat Treatment (PWHT) after welding, however sometimes it is very difficult or even impossible to perform. One of the ways to eliminate PWHT while obtaining the required properties of the joint is to use the so called temper bead welding technique. This paper presents results of non-destructive (visual testing, penetrant testing, radiographic testing) and destructive (bending test, tensile test, impact strength, macro- and micrograph, hardness measurements,) tests for a new generation steel PB2 assigned to the power industry. The major objective of the examinations was to verify properties of welded joints made of PB2 steel welded with and without PWHT.
