Welding process. The mechanical properties of welded joints must meet the welding requirements and should be considered during design and manufacture.
Preheat before welding. The ambient temperature of 15CrMo steel should be in the range of -20℃~+80℃ to prevent overheating and deformation.
The welder should check the chemical composition (mass fraction), mechanical properties and metallographic structure of the preheated weldment before welding, and the next process welding can only be carried out after passing the test.
During the welding process, the 15CrMo steel should be prevented from overheating and deformation.
15CrMo steel weld defects shall be inspected after the weld defects are repaired, and the results shall be indicated in the contract and signed and agreed by the supervisory engineer before use.
Advantages of 15CrMo steel
1) High-quality carbon structural steel and low-alloy structural steel are used after cold rolling and hot rolling.
2) The surface quality of 15CrMo steel is good, which can meet the standards of JISJ127-2 and GB/T1275-2003.
3) 15CrMo steel has a long service life.
4) The price of 15CrMo steel is low and competitive.
5) The production cost of 15CrMo steel is low and the benefit is high, which is beneficial to the development of enterprises and the improvement of production technology.
