本文从企业实际出发,对压力容器焊接工艺计算机辅助设计系统开发进行简要阐述,通过计算机辅助系统进行功能模块设计,建立完备的数据库,完成对焊接工艺流程的设计,从而达到保障设备安全、节省企业成本、增强企业竞争力的预期效果。压力容器设备在密封、高压、高温、低温环境中应用广泛,对焊接质量要求非常高。在国内外发生的压力容器安全事故,大多由于压力容器本身的焊缝所引起的,也就是焊接质量出现了问题。而引入计算机技术辅助设计系统,能有效提高压力容器焊接技术,改善焊缝性能,进一步保证压力容器的安全,也能够使生产企业节省资金、缩短 Based on the reality of the enterprise, this paper briefly introduces the development of computer aided design system of pressure vessel welding process, designs functional modules through computer aided system, establishes a complete database, and completes the design of welding process so as to ensure equipment safety and save enterprises Cost, enhance the competitiveness of enterprises expected results. Pressure vessel equipment in sealing, high pressure, high temperature, low temperature environment is widely used, the welding quality requirements are very high. Occurred at home and abroad pressure vessel safety incidents, mostly due to the pressure vessel itself caused by the weld, that is, the quality of the welding problems. The introduction of computer-aided design system can effectively improve the pressure vessel welding technology to improve the performance of the weld, to further ensure the safety of pressure vessels, but also to enable manufacturing enterprises to save money and shorten
