Is welding of nm400 steel sheet suitable for laser cutting

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the welding of NM400 steel sheet rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of welding of NM400 steel sheet steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

EN10028-2 P235GH steel plate is a non-alloy quality steel with high temperature performance, executive standard: EN10028-2. Steel number: 1.0345. welding of NM400 steel sheet, P235GH pressure vessel steel has good plasticity, toughness, cold bending performance and welding performance. The P235GH presure vessel plate and sheets size, shape and allowable deviation of the steel plate should meet the requirements of EN10028-1 2007 + A1: 2009.

For the team, cooperation is the core idea of daily work, and the core of common cooperation is resource sharing. With a perfect resource sharing mechanism, the whole team can be called a unity spirit.A good team lies in the ability to transfer resources, knowledge and information in time among team members in order to achieve the common goals of the team. So that we can share experiences and lessons."
