Which might fall through the tube opening into the dephlegmator header if not covered. The temporary installed steel sheet is to be removed after the steam distribution duct has been installed.

建议使用 1.5 mm 钢板覆盖管口处，以避免损伤并减少掉入逆流凝汽器联箱的焊渣等，如不覆盖，焊渣可能通过管口处掉入联箱。

At the same time there are all kinds of wire, Flux, Hange equipment and supplies, and other accessories.

Shanghai Jinfeng Hange Machinery Manufacturing Co., Ningbo Jinfeng Hange Machinery Manufacturing Co., chairman of Germany chapter, both created in Shanghai.

上海金凤焊割机械制造有限公司，是宁波金凤焊割机械制造有限公司董事长章德均先生在上海创建的。

As the steel carbon and alloy elements working together to make it extremely easy to lead in the welding hardened organization, welding poor performance should be this, pearlitic heat-resistant steel in general preheating before welding, after welding tempered.

由于钢中碳和合金元素的共同作用，使其在焊接时极易形成淬硬组织，焊接性能较差，应此，珠光体耐热钢一般焊前进行预热，焊后进行回火处理。

EGW (CO2 as shield gas) has been used prevailingly in vertical welding of large storage tank. But it's easy to make linear porosity in welding.

气电立焊（CO2气体保护）气电立焊技术已经广泛应用于大型储罐的壁板立缝焊接。

Its are main the task is to produce welding flux kind product -- the recipe dissolvent that will come from French flounder and metal (lead - stannic alloy or stannum - silver-colored - copper alloy) mix and become, in order to passes drill rod solder will yuan parts of an apparatus is fixed in printed circuit board on.

其首要任务是出产焊剂类产物——将从法国辗转而来的配方溶剂和金属(铅-锡合金或者锡-银-铜合金)同化而成，用以经由过程钎焊将元器件固定在印刷电路板上。

Even if you would not use any soldering past, but preforms without flux, you will get a perfect wettening of the surfaces and a voidless connection.

即使你之前没有进行过焊接，而且焊片不带焊剂，焊接面也可以得到良好的润湿，并且空率很低。

In this article, a study on stability of 4-layer brazed steel tubes forming is firstly tried in this field.

本文对四层卷焊管成型稳定性所进行的尝试性研究，在卷焊管稳定性研究领域尚属首次。

The microstructure and phase composition of the brazed zone were analyzed and its mechanical properties and gas leakage were tested.

分析焊区的显微组织形态、相组成，测定焊区力学性能和气密性。

Many leading cleaning chemistries clean the majority of the flux packages, but some are incompatible with the flux chemistry.

许多主流的清洗剂可清洗大部分焊剂，但却与某些焊剂在化学成分上相互冲突。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
