Q345qC steel plate is the steel plate of bridge structure, the implementation standard is GB / T 714-2015 standard. S275N carbon steel plate sheet, Q345qC-Z25 steel: Q represents the yield strength, 345 represents the small yield strength, the unit is MPa, q is short for the bridge, C quality grade, corresponding to the corresponding impact temperature and impact work value, Z is the Z-direction performance that is the performance of the steel plate thickness direction, Z25 is the Z-direction Performance level requirements.

As the thickness and hardness of S275N carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the S275N carbon steel plate sheet from cutting cracks, preheating should be carried out before S275N carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire S275N carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S275N carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.
