weldment

The specimens for fretting wear test were cut from the as-weldweld zone metals for qualified weldment.

在焊接检验合格的焊态试件上从焊缝区、熔合区和焊接热影响区金属中分别截取并制备微动磨损试验用试样.

It is more usual to complete the weldment first and then to galvanize it.

所以常用的方法是先把钢板焊起来再镀锌.

Special welding equipment must be developed , to achieve Cu-Al pipe weldment in quality.

为实现铜 - 铝管的优质焊接,需要研制相应的焊接设备.

Note: Both parts exactly the same-A 01 ER is called for on 2089355 A 01 , A 02 weldment to avoid ordering double requirements.

注意: 注解部分 A01ER 与2089355A01,A02两部是刚好咬合的.

Under the low-order natural frequency's vibration, weldment's mean stress value reduces about 40 %-55 % .

在 低阶 固有频率的振动下, 焊接件的平均应力值降低 40%-55% 左右.
