Correct welding method for 05CuPCrNi grade steel

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the 05CUPCRNI grade steel production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

All steel pipes operated by our company are in compliance with national standards, and the original bill of materials of steel mills is attached. At the same time, we supply the 05CUPCRNI grade steel seamless steel pipe, electrical Resistance Weld pipes, large diameter welded pipes ordering business of various specifications and materials and the railway and road transportation business for the majority of users.

Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image 05CUPCRNI grade steel processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the 05CUPCRNI grade steel steel plate.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of 05CUPCRNI grade steel, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent 05CUPCRNI grade steel products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the 05CUPCRNI grade steel technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
