As the thickness and hardness of S690QL plate increase, the tendency to crack at the cutting edge increases. In order to prevent the S690QL plate from cutting cracks, preheating should be carried out before S690QL plate cutting. Special attention should be paid to preheating to make the entire S690QL plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S690QL plate cannot be preheated, the partial preheating method can be used instead.
