Question

哪位大侠能帮我翻译成英文啊，急急急、、、、

本文是探讨CO2气体保护焊的操作及在造船中的应用，并以3G焊接工艺为例对CO2焊接工艺过程、CO2气体保护焊操作规程、CO2气体保护焊的缺陷极其产生的产生原因等进行的叙述。目前，CO2焊接是国内外船厂中最常用的焊接工艺方法，它不仅焊接成本低、生产效率高，而且焊接变形小、操作简单，因此，CO2焊接逐渐替代了原先的手工电弧焊，大大缩短了造船周期，提高了生产效率，增加了公司的效益。本文根据DNV及KR的焊接标准及规范，对船厂中CO2焊接的施工工艺、操作工艺以及焊接过程中和焊后出现的问题及缺陷所作的具体要求，针对具体的缺陷及问题陈述具体的解决方法及其避免方案，并要求焊工及检验人员对焊缝所进行检验要求和标准，以使焊缝外观及质量达到标准要求。

This paper is to investigate the CO2 shielded welding operation and the application in shipbuilding, and with 3G welding process as example to CO2 welding process, CO2 shielded welding procedures, CO2 gas shielded welding defects extremely produce reasons etc narrative. At present, the CO2 welding is the most commonly used domestic and foreign shipyard welding method, it not only welding low cost, high production efficiency, and the welding deformation small, simple operation, therefore, CO2 welding gradually replaced the original manual electric arc welding, greatly reducing the shipbuilding cycle, improve the production efficiency, increase the company's benefit. According to the welding standard and KR DNV in specification, to the shipyard and construction craft, the CO2 welding and welding process and operation process of the problems and after welding defects have specific requirements for specific defects and the problem statement the concrete solution and avoid scheme, and requires welder and inspection personnel conducted to weld inspection requirements and standards, in order to make weld appearance and quality to meet the standard.
