Weldability of Structural Steels

Weldability of Structural Steels

If weld preparation is excellent and operator-induced defects (e.g., lack of penetration or fusion) are avoided, all the standard structural steels can be successfully welded. However, several steels may require special treatments to achieve a satisfactory...
Hydrogen Embrittlement

Hydrogen Embrittlement

Hydrogen embrittlement can occur when metals are exposed to hydrogen gas or certain hydrogen-containing compounds. When hydrogen atoms diffuse into metal, they can weaken the metal’s atomic bonds and cause it to become more brittle and prone to cracking or...

Wet H2S Damage in Oil and Gas Systems

Wet H2S Damage in Oil and Gas Systems

Hydrogen sulfide (H2S) is a highly toxic and corrosive gas that poses significant challenges to the oil and gas industry. When in the presence of moisture, H2S can cause severe damage to equipment and infrastructure, leading to:  Safety hazardsProduction...
Porosity in Welding

Porosity in Welding

Porosity in welding refers to the presence of voids or gas pockets within a joint. It is a welding defect that can weaken the integrity and strength of the weld. Porosity appears as small holes or cavities within the metal or at the interface between the weld and the...
