This paper presents the investigation on welding of ASTM A 106 Grade B pipes to access
the quality of weldments for mechanical and metallurgical characteristics by varying the …

In this study, a series of optical microscope examinations, constant loading rate indentation
(CLR), and creep indentation (CI) tests were performed on room temperature to investigate …

This investigation aims to make clear the relationships among geometric features,
macrostructures, microstructures, and mechanical performances of the weld bead in the gas …

Purpose: The residual stresses in different welding methods are fundemental problems to
consider. Friction stir welding is one of a solid state joining process, it is economical in that it …

The present work reviews and interprets weld bead's patterns especially on solidified weld
surfaces. Defects patterns such as rippling, humping, and other unexpected surface patterns …

In this study, the effect of the tool rotational speed on the microstructure evolution and its
significance on the mechanical properties of friction stir welded 9Cr-1Mo (P9) steel is …

API 5L X80 steels are widely used in welded pipes in the petroleum industry. However,
microstructural changes in the heat affected zone are a concern when welding such pipes …

This paper proposes the temper bead welding (TBW) technique as an alternative to post-
weld heat treatment (PWHT) by varying the polarity between the deposited layers while …

Overlay welding with stainless steels has gained attention in several sectors of industry by
increasing the mechanical and electrochemical properties of surfaces, in order to obtain …
