Cutting service of high quality 16mo3 steel

Key points of welding joint design: under the condition of satisfying the requirement of welding penetration depth and weld density, small welding groove Angle and gap should be adopted.In the high quality 16Mo3 steel Angle joint, a symmetrical groove or a groove inclined to the side plate is used.Double - sided groove symmetric welding is used instead of single groove asymmetric welding.In a T-shaped or Angle joint, the end of the plate subjected to welding tensile stress in the thickness direction extends out of the joint weld zone.

P265GH is a non alloy quality steel with high temperature performance, executive standard: EN10028-2, number: 1.0425. P265GH plate belongs to medium pressure boiler steel plate. It is a kind of steel plate for pressure vessels in Europe. high quality 16mo3 steel, P265GH plate has good plasticity, toughness, cold bending property and weldability. The equivalent steel grade in China of P265GH is 25MnG.

The preheating temperature, the power of the flame, including the flow of acetylene and oxygen, will increase with the increase of the thickness of the high quality 16mo3 steel steel plate. If the nozzle is diffused and the oxygen curtain type, the power of the flame should be higher when cutting steel plates below 20mm to speed up the cutting speed and make the cutting speed sufficient.
