Intergranular corrosion (IGC) behaviors of X65-Inconel 625 clad pipe welded joints of
different thickness (1.5, 2.0, 2.5 mm) were investigated. Corrosion tests showed that as the …

High strength steel welded joints are usually fabricated by heterogeneous weld metal for
reducing the negative impacts of microstructural characteristics and defects on mechanical …

The use of cold metal transfer process (CMT) is an excellent alternative to depositing nickel-
based alloys on oil and gas pipelines due to the relatively small dilution. However, sulfide …

The effect of post-weld heat treatment (PWHT) on the microstructure, penetration and
distribution of hydrogen, and sulfide stress corrosion cracking (SSCC) behavior was …

Sulfide stress cracking (SSC) failure is a main concern for the pressure vessel steel Q345
used in harsh sour oil and gas environments containing hydrogen sulfide (H2S). Methods …

Resistance spot welding is widely used in the automobile, ship, and food industries. The
durability and safety of the product being produced from these different industries depend on …

This work aims to find suitable 42CrMo4 steel grades for working in energetic applications
dealing with high pressure hydrogen gas. Consequently, the influence of the tempering time …

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 …

The hardness response of Alloy 625 weld overlay on low alloy steel was evaluated under a
range of aging conditions to determine how the properties of the overlay change during …

Dissimilar metal welds (DMWs) are routinely used in the oil and gas industries for structural
joining of high-strength steels to eliminate the need for post-weld heat treatment (PWHT) in …
