Evaluating risk of hydrogen embrittlement: new simulation of cold cracks in high-strength steels

which can lead to crack formation in the welded component. Alongside the hydrogen which is introduced during the welding process, previously existing hydrogen in the steel is loosened up by the weldin... read more

Economic avoidance of weld metal hydrogen cracking when welding modern C-Mn steel

During the last decade or so considerable financial investment in steel processing and production has been aimed at reducing the risk of hydrogen cracking in the heat affected zone (HAZ) of weld and h... read more

Flux-Cored Wire creates low-hydrogen welds in pipelines.

Fabshield® X90 ensures welds remain ductile and resist cracking with low-temperature impacts. Diffusible hydrogen designation of 6.2 mL/100 g of weldment further minimizes chance of cracking. Availab... read more

Pipeline Whistleblower: Cracks in The System

When the steel cools, the hydrogen can get stuck and cause delayed cracking. It has long been a major issue in pipeline and building construction around the world. Examples of welding failures causing ... read more

High Temperature Hydrogen Attack: Safe use of carbon steel

The effect is most notable in welds and other ... with the hydrogen penetrating further through the steel structure, so that over time, tiny pockets of methane coalesce, leading to fissuring and ultim... read more

Avoiding stress fractures in towers through welding innovation

Pre-heating will also prevent the build-up of cold cracks, which can occur due to hydrogen exposure or internal stress in the component. “This is particularly important when treating high strength ste... read more

Gas-Shielded Flux-Cored Wire offers low hydrogen weld deposit.

In addition to minimizing risk of underbead cracking, FabCO® 750M provides low diffusible hydrogen weld deposits (3.5 mL per 100 g of weldment) on high-strength applications. Minimized spatter and f... read more
