焊缝

The right lower posterior chest showed dullness on percussion with moist rales at the end of inspiration on auscultation.

对塞焊焊缝的详细检查表明在焊渣及气孔附近，焊缝中存在着人字型裂纹。

The welding juncture of the axis head and the surrounded plate in the holding circle of bessemer converter crack severely .By means of analysis to the material,the structure and the process,we find out that one of the main reason of crack is the thickness of welding plates vary a lot, the other is that it isn't penetrable for welding.

转炉用托圈的轴头与围板焊接处严重开裂，通过对其材质、结构、工艺进行分析，找出接头断裂的主要原因，一方面是由于焊缝连接件厚度相差悬殊，另一方面是由于焊缝未焊透，这两方面原因造成应力集中。

Based on the tests of fracture toughness of welding seam, this paper gives a new method to evaluate the breaking strength of welding seam.

本文通过线切割缺口试样拉伸试验方法研究了带钢不同焊缝的抗断裂能力，并对焊缝抗断裂能力进行了评价。

The butt weld is easier to inspect nondestructively than the fillet welds.

对接焊缝比角接焊缝更容易进行无破坏检查。

And the welding connecting of them are advised to use slope butt weld that are fully welded, but when the double-sided fillet weld is used, they should be design on equal strength.

节点中的焊接宜采用完全焊透的坡口对接焊缝连接，当采用双面角焊缝连接时，可按等强设计。

Finally temperature distribution curve of each point and the size and distributed rules of the welding residual stress in welding line.

最后通过后处理，得出了不同时刻焊缝处各点的温度分布曲线及焊缝部位残余应力的大小及分布规律。

The study of loading path optimization for tube hydroforming process;2. Based on some of the research results of the authors,the influence of the weld properties on tube hydroforming .

结合研究成果讨论了焊缝材料性能对管材液压成形规律的影响，阐述了焊缝管液压成形的研究现状及发展趋势，以及亟待解决的关键问题。

Reducing bond temperature and diminishing bond time are in favor of the mollification of interface stresses.

分析表明，对接头有害的较大的残余应力区域分布在膨胀系数较小母材靠近焊缝附近的地带，而残余应力的最大值出现在其界面脆性相及焊缝附近靠近接头边缘的微小区域，降低连接温度、减少连接时间有利于减小接头残余应力，优化接头的界面应力状态。

The expatiation of the control function in this article is divided into two sections: the manufacturing execution system and the basic automatic control. The former was focused on the quality assurance system of pipe welding and the quick-setting system,and the later focused on the control functions,such as the roll gap position control, the tracking of cross-welding line between coils,the sequence control, the speed control over the main driver, edge miller, cut-off machine, HF welder and the heat treatment of weld seams.

分制造执行级MES 和基础自动化级两部分阐述控制功能，MES方面着重介绍快速设定系统和焊接质量保证系统；基础自动化部分重点介绍辊缝位置直控制、钢卷对接焊缝跟踪、顺序控制、主传动速度控制及铣边机、飞锯、高频焊机、焊缝热处理等单体设备的控制功能。

All reflections from uncorrected areas having responses that exceed 50% of reference level shall be recorded.

1.4本规程不适用于单面焊部分焊透焊缝的检查，也不适用于奥氏体钢焊缝的的检查。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
