At present, thermal energy storage serves to time-shift power generation at temperatures reaching up to 600C; however, several research initiatives are investigating operation at even higher
Storage tank fabrication can present welding challenges. Learn how submerged arc welding solutions can improve results in storage tank construction.
The failed bellows (bellows-8) were cut and specimens were extracted for examination of pitting using confocal and scanning electron microscopes. The micro-hardness of the material from the failed bellows was also measured at 10 N load with a dwell period of 15 s.
Causes of Rust Formation in Welds Rust formation in welds can occur due to exposure to atmospheric moisture, improper storage of welding materials, or inadequate cleaning of base metals prior to welding.
This article aims to analyze some common failures that can occur in energy storage spot welding machines, their potential causes, and possible solutions. Understanding these issues can help operators troubleshoot and resolve problems effectively, minimizing downtime and

T-joint welding is a key manufacturing process of large storage tanks. However, complex residual stresses are generated and have a great effect on the structural integrity of storage tanks.
Abstract and Figures This paper presents the failure analysis of AISI-304 stainless steel tank that was fabricated by welding and used for the storage of styrene monomers.

The brine storage tank was reported to have failed during service due to localized corrosion, primarily at some points in the heat-affected zone (HAZ). Some pits were also observed on the base metal far away from the weld joint.
Storage tanks can present welding challenges. Learn how subarc welding solutions can optimize results in storage tank construction. To support global energy and manufacturing demands, the outlook for construction of bulk storage tanks and terminals remains positive.
Welding failure refers to any deviation from the desired or expected outcome in a welded joint. It encompasses a wide range of defects that can occur during the welding process, leading to compromised structural integrity or performance.
Even when the cause of weld defects may seem obvious, careful forensic investigation reveals opportunities to save time and money. The case studies below illustrate how weld failure analysis results can pinpoint vulnerabilities and areas for improvement in the welding process.
This is especially true in aerospace, transportation, and energy sectors where metallurgical weld failures often result in catastrophic events that are extremely costly; and, even worse, end up taking human life. The weld-metal itself; however, should not always be the very first thing to blame.
Poor weld preparation, such as inadequate cleaning or improper joint geometry, can lead to welding defects and reduced weld quality. Insufficient removal of surface contaminants, such as rust, oil, or paint, can result in contamination of the weld pool and the formation of defects like porosity or lack of fusion.
Incomplete fusion creates weak points within the weld, making it susceptible to premature failure under load. Additionally, incomplete fusion can lead to porosity, which further reduces the mechanical properties of the weld and increases the risk of crack initiation and propagation.
