Air distribution piping systems almost invariably use soft copper tubing with soldered fittings . 压缩空气的分配管道系统无例外地都是用焊接管件的铜管。
Usually, glass insulated terminals are either soldered or cemented into the throughhole in the case . 通常是把玻璃绝缘接线端焊接或者是粘合在壳体上的通孔内。
One cause of delay in the development of new steels has been that welds have failed, causing cracking . 阻碍新钢材发展的一个原因是焊接曾遭到失败，产生了裂纹。
The puddle section for heavy duty batteries must be at least the thickness of the base of the poststrap . 重型汽车蓄电池极柱焊接部位至少要等于极柱底座的厚度。
The stainless tubing is less likely to kink than copper, but it is harder to solder without an acid treatment . 不锈钢管比铜管不易纠结，但不经酸性处理焊接较困难。
We had some unexpected problems with our new robotic welders in the factories, which led to production snags . 我们工厂里的新自动焊接机发生了未能预料到的问题，从而导致生产的障碍。
A source said the burn-through probably occured at a seal point between the booster's third and fourth sections . 一位提供消息的人说，烧穿点可能发生在火箭的第三和第四部分之间的焊接点上。
A large number of these cracks occurred because the groove welded component was considered a secondary member or attachment . 发生这许多裂纹是因为把这些坡口焊接部件作为次要构件或附件考虑。
These attachments were considered secondary components, so no weld quality control has been imposed on the groove weld splice . 这些附连件被看作是次要的部件，所以在这种坡口焊接中没有进行焊接质量控制。
To evaluate fracture instability, the total sum of stresses due to residual welding or rolling stresses, dead load, and live loads must be considered . 计算断裂失稳性时，必须考虑焊接或轧制残余应力，恒载应力和活载应力之总和。
