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 AH36 ship building steel plate 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.
The production of ah36 ship building steel plate needs to be normalized by means of controlled rolling and controlled cooling or heat treatment processes with more complete equipment. At the same time, the internal steel purity of the supplied billets is required to be high, especially the content of S, P, N, 0 and H in the steel should be strictly controlled.
At present, the ah36 ship building steel plate steel plate cutting is mostly by laser, is charged on time, such as an hour between 400 yuan to 1000 yuan. Of course, different regions, the price also has big difference. The price of steel plate cutting in the south is relatively high, and the north because of the former heavy industry is more developed, so the price of ah36 ship building steel plate cutting is relatively low. Of course, no matter what kind of laser cutting steel plate, its price float is also in this range, if the price is higher than this range, you need to choose carefully.
Ningbo port has trade and transportation with more than 50 countries and regions, such as the United States, CIS countries, Europe, Africa, Japan and South Korea, Southeast Asia, the Middle East and Hong Kong. Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.
