The results show that : basic manufactured tank, welders were no longer needed in Tooling process, the cutting process is not strictly adhered to. Defects generated through the floor to form oil leakage is the main reason production base metal microstructure revealed the existence of a more serious segregation, makes steel welding performance is changing for the worse. Failure welding defects as easily lead to hidden dangers.

结果表明：油罐基本制造完成后，焊工在切除不再需要工装过程中，不严格遵守切割工艺，所产生的底板贯穿性缺陷是形成油罐泄漏的主要原因，金相显示制作母材中存在着较严重的偏析，使得钢材的焊接性能变得较差，容易引起焊接缺陷成为失效隐患。

This process is makes the improvement in the original two person two-sided synchronized GTAW process which one time welding two-sides formings, we have carried on a series of welding testing on 8mm SUS304, this new process has be able to decrease weld defects on the tradition two person on both sides synchronized GTAW process, shortenned construction work period, increase welding quality, as well as eliminate tradition two person on both sides synchronized GTAW for SUS304 austenite stainless steel in easy emergence of incomplete joint penetration and porosity.

此工艺是在原有的双人双面同步钨极氩弧焊工艺基础上进行的，即将原有的一次焊双面成形改为两次焊成形，经过在厚度为8 mm的SUS304上进行的一系列焊接工艺试验，验证了这项新工艺既减少了传统工艺中繁琐的工艺过程和焊接工艺缺陷，缩短了施工工期，提高了焊接质量，又消除了传统8 mm SUS304不锈钢双人双面同步钨极氩弧焊过程中易出现的未焊透和咬边现象。

This article has mainly studied one kind improved two person two-sided synchronized GTAW craft for the austenite stainless steel. This craft makes the improvement in the original two person two-sided synchronized GTAW craft foundation which one time welding two-sides formings. A series of welding engineer testing on 8 mm SUS304 were carried on. The new craft could guarantee the welding quality in contrast with the original two person two-sided synchronized GTAW.

Welding completed, should be removed arc OFC boards and grinding formation, while the hammer down; Slag : After removal of the entire weld slag, welders self (including weld appearance and size, etc.) there is no problem, before relocation to continue welding

焊接完毕，应采用气割切除弧板，并修磨平整，不许用锤击落；清渣：整条焊缝焊完后清除熔渣，经焊工自检确无问题后，方可转移地点继续焊接。

According to the property of EBB, scanning electron beam was considered as plane heat source instead of spot heat source in this paper. Aiming at the problems to measure the real-time temperature and residual stress of radiator difficultly at high temperature, the two-dimensional finite element models were established. Based on the thermal elastic-plasticity, the temperature fields and stress fields of EBB 6139T and 6204T radiator by two kinds of process were simulated by the software of ANSYS. It is of great value and significance to guide actual production.
