Taking a heavy truck cab as the example, a model of the spotweld space based on finite element was built to analyse the torsional stiffness of the model, and the amount and layout of the spotweld using the discrete variable topology optimization were optimized. Comparing with the original model in welding spot's number and the torsional stiffness, the optimized model has less number of welding spot, but the torsional stiffness of the two model is almost the same.

以某重型卡车驾驶室为例，在有限元模型基础上建立焊点空间模型进行扭转刚度分析，并采用离散变量拓扑优化方法对焊点的数量及空间布局进行优化，通过优化前后的对比可知，优化后在不降低扭转刚度的同时减少了焊点数目。

A physical model of the forming process of equiaxed grain in weld nugget zone during friction stir welding of aluminum alloy was established.

Since the entire pad on the wafers must be overprinted to achieve an acceptable reflowed bump size, when overprinting is done on tight pad pitches, the apertures must be positioned with enough space between them so that bridging defects do not occur.

因为晶片整个焊盘应过量印刷锡膏以达到课接受的回流峰尺寸。当焊盘锡膏在焊盘斜度过渡印刷时，孔间应有足够的空间，这样才不会产生连锡。

The sepctrum structures and the differences between TIG and MIG welding arc are analysed.The corresponding relations between metal transfer and welding arc spectrum structure are pointed out especially.

通过分析得出了TIG焊电弧光谱空间分布的差异性和MIG焊电弧光谱空间分布的相似性，着重指出MIG焊电弧光谱与熔滴过渡之间存在密切关系。

To get a property comparison of GXHJ－ 1 sintered welding agent with SJ101 sintered welding agent, related tests were carried out, including deposited metal test, lab butt－ joint plate test, single－ welding stick operation test, double－ welding stick operation test as well as operation test with H08C welding stick, focusing differences of the two in terms of technological properties and weld seam impact toughness.

为了比较 GXHJ－ 1和 SJ101两种烧结焊剂的性能，分别从熔敷金属性能试验、实验室对接板试验、单丝焊生产、双丝焊生产等方面及在匹配 H08C焊丝的条件下进行了工艺性能和焊缝冲击韧性对比。

The feedback of К190ПК rail flash welding machine was low, and it's difficult to weld U75V steel alloy rail with continuous flash butt welding process. The software and hardware of control system has been reconstructed to solve these problems.

针对К190ПК钢轨闪光焊机响应速度慢，只具有连续闪光焊工艺，难以实现U75V钢轨的焊接等问题，对焊机控制系统的软、硬件进行了改造。

It can be used to weld aluminum alloys and titanium alloys, which are difficult for fusion welding. It especially has great potentials in friction welding of non-axisymmetric components.

它可以焊接通常用熔焊方法难以焊接的铝合金、钛合金等，尤其是在非轴对称焊件的摩擦焊中拥有巨大潜力。

We have more than 100 different type welding machine,including traditional welding maching,argon welder,gas shielded welding machine,auto-weding machine.

拥有上百台不同类型的焊接设备，包括普通电焊、氩弧焊、气体保护焊、自动焊等，可以满足不同要求、不同材质的产品焊接。

For example, apply to light welding steel, aluminium, copper and other new materials Compuspot HF welder series, melting a microprocessor-controlled gas welding welder series.

例如适用于焊接轻型钢、铝、铜及其它新型材料的Compuspot HF焊机系列、微处理器控制的熔化极气体保护焊焊机系列。

Since the entire pad on the wafers must be overprinted to achieve an acceptable reflowed bump size, when ov ERP rinting is done on tight pad pitches, the apertures must be positioned with enough space between them so that bridging defects do not occur.

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%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
