The plate lugs should be dry before they are immersed in hot liquid lead of the cast-on machine . 在极耳被浸渍到铸焊机的热铅液中之前，极耳应是干燥的。
Brazing of aluminum and aluminum-base alloys is accomplished with the aluminum-silicon brazing alloys . 铝和铝基合金的铜焊是用铝硅铜的合金来完成的。
A number of metals and alloys, how ever, are difficult to silver-solder and require special procedures . 但是有许多金属和合金是难于银焊的，因此需要采用专门的工艺方法。
The second crack is a crack originating at the groove weld toe of the column flange-girder flange connection . 第二种是产生于立柱翼缘与主梁翼缘连接处的坡口焊缝焊趾处的裂纹。
When all the gold does not dissolve in the solder brittle failure occurs near the goldsolder interface . 当所有的金不能完全溶解在焊钩中时，就会在金与钩的界面附近发生脆性破坏。
The etched section also reveals that multiple weld passes were made over the top of the original submerged arc weld pass . 从酸蚀断面还可以看出：在原自动埋弧焊的上面覆盖有多层焊道。
Close examination of the plug welds showed the existence of herringbone patterns near the slag and voids in welds . 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。
Energizing the machine "start" switch places the machine in an automatic single cycle operation that completes the element assembly . 开动机器，进行一次自动循环运转就完成极群组的铸焊。
These cracks occurred at either the beam flange or in the column flange depending on the reentrant corner weld angle . 这些裂纹视凹形焊角的不同，或者出现在横梁翼缘上，或者出现在立柱翼缘上。
Cracks, growing at weld toe, tend to form at numerous sites along the transverse width perpendicular to the applied stresses . 焊趾处萌生的裂纹往往在垂直于作用应力方向沿着横向宽度在多处形成。
