Considering the characteristics of the main container manufacturing for pressure vessels

ration calculation empirical formulas for welding consumable were provided in combination with years of actual production practice. In order to improve the efficiency and accuracy for technician to calculate the consumption

ration calculation software for welding consumable（WCRC） was developed. Ration calculation can be achieved quickly with GUI interface operation. The capsulation of ration calculation software was studied also in this paper to protect the source code and improve universality

and the housed software can operate independently without the installation of MATLAB software. In addition

technicians applied the software to actual production application for the purpose of verifying its’ reliability. The result shows that it can meet the calculation requirements of our company. This can enhance the produce practicality and provide better basis for the integrated calculation of pressure vessels because of the development of ration calculation software.
