查询词典 tack weld

Spot checks contractor piping isometrics or fabrication drawings showing weld procedures, filler metal, pre-heat and post-weld heat requirements and monitors their use.

The results show that, the coefficients of welded joints are both greater than 0.9, but the yield strength of weld joint filled with Al-Mg-Zr-Sc welding wire is greater 100 MPa than that of filled with Al-Mg-Zr welding wire. It indicates that the Al-Mg-Zr-Sc welding wire is the best alteration of filling materials to weld of Al-Mg-Sc alloy.

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。

On the other hand, the cooperation didn't extend to the appointments process: Jesse Helms was holding up my nomination of the Republican governor of Massachusetts, Bill Weld, to be ambassador to Mexico because he felt Weld had insulted him, and Janet Reno told the American Bar Association that there were 101 vacant federal judgeships because the Senate had confirmed only nine of my nominees in 1997, none for the court of appeals.

另一方面，这种合作精神并没有延伸到任命程序上。杰西·赫尔姆斯阻止我任命马萨诸塞州的共和党州长比尔·韦尔德为墨西哥大使，因为他觉得韦尔德曾侮辱过他，珍妮特·雷诺对美国律师协会说，有101个联邦法官的职位空缺，因为参议院在1997年只批准了我任命的九个人，没有一个人被批准担任上诉法院法官。

This article introduced application of digital laser vision technology in several key links during welded pipe manufacturing,including realizing weld tracking,adaptive adjusting welding parameters or angle of driving the strip, measuring coil plate width and edge contour,measuring steel pipe diameter,and automatic inspecting weld profile and defects,etc..

介绍了数字激光视觉技术在焊管制造过程中多个关键环节中的应用，包括实现焊缝跟踪，焊接参数或钢带送进角度的自适应调整，钢板宽度与边缘形状的检测，钢管外径的测量，焊缝成形及缺陷的自动检测等。

The results show that the main cause of the angular distortion of the lap joint is the non-uniform distributed inherent shear strain component that is vertical to the weld line and exists in the plane paralleling to the weld line.

结果表明：搭接接头焊接角变形的产生主要是由焊缝及其附近区域与焊缝平行的平面内垂直于焊缝方向上不均匀分布的固有剪切应变分量引起的。

The study of the fusion-welding process covers various important aspects such as the metallurgical properties of the weldments, the effect of arc temperature on the development of post-weld residual stresses, distortion in the base material, the physics and behaviour of the arc with the formation and maintenance of the weld pool.
