Preventive measures: for cold cracks, the welding rod with good crack resistance, low hydrogen or ultra-low hydrogen and low strength should be selected, and the preheating temperature and linear energy should be controlled to reduce the tendency of cold cracks. For hot cracks, the steel with h...
Hot cracking is also known as hot shortness, hot fissuring, solidification cracking and liquation cracking. Advertisement Corrosionpedia Explains Hot Cracking These cracks are known as hot cracks because they occur immediately after welds are completed and sometimes while the welds are in progress, wh...

Most importantly,ensure that yourwelding hood is operating correctly. This means that your lens does not have cracks in it, there are no gaps around the edges, etc. A miniscule crack in a welding lens can cause flash burn. This often happens when being exposed to UV light even only for ...
The results indicate that the cracks were embedded in middle of multiple beads of WM. The fracture surface reveals the dendritic solidification structure of WM, which contains impurity element sulfur and other alloy elements (Ti, Al, and O) originating from the filler core of welding wire. The...
