Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. quenched and tempered GL-E40 hull steel plate, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.

Laser deep penetration welding is to radiate a high-power density laser beam onto the welding material. The material converts the absorbed light energy into heat energy, and is heated to evaporate to produce metal vapor. Under the action of the reaction force generated when the metal vapor leaves the surface of the workpiece, the molten metal liquid flows around and forms pits.
API 2H gr50 is carburized steel, which is usually low carbon steel with carbon content of 0.15% - 0.24%, and is used for offshore platform structure. API 2H gr50 steel is suitable for surface carburizing and hardening treatment, with good workability, small deformation and good fatigue resistance. quenched and tempered GL-E40 hull steel plate, API 2H gr50 steel is used for making hull, offshore oil production platform, platform pipe joint and other structural parts.
