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

Experts Explain Causes Of Cracks In Welding

The high carbon content in the welding rods apparently led to overly rapid cooling, and that produced cracks. One expert said that sounds like "hydrogen-cracking" or "cold-cracking," a problem that oc... read more

Welding Cracks Caused Union Oil Blast Fatal To 17

Cracks ... year at the Union Oil Refinery in Romeoville, says a report issued Friday by the state fire marshal. The report, prepared by Packer Engineering Associates, found that a network of cracks fo... 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

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
