焊接接头

Based on the construction and weld joint of box-type head frame ,the characteristics of MAG welding and submerged-arc welding are discussed,it is proved that by using these two efficient methods,the welding quality is highly improved,and the efficiency is also raised.

从箱式井架的结构形状和焊缝接头形式出发，针对MAG焊和埋弧焊的特点进行了论述，生产结果证明，通过两种优质、高效方法的运用，使焊接质量得到了保障，生产效率得到很大提高。

Even though 7075 aluminum alloy with worse weldability, the value of the tensile strength of it's joint with filler powder was 360Mpa and was as 78% value as that of the base metal.

焊缝强度较未填粉时有大幅度提高，达到了母材的78%。标签铝合金激光焊接填充粉末接头强度 aluminum alloy laser welding filler powder tensile strength of welding joint

It shows that the strength and the elongate rate of joint increased earlier and then decreased with the welding velocity increasing,when the welding velocity was 200 mm/min the strength was highest (coefficient was 67%).

用这种连接方法能避免熔焊时的缺陷，得到的接头变形小、强度高，能焊接所有牌号的铝合金，包括以前被认为不可焊的铝合金[2，3]。

In the wire workshop of the manufacturing industry of the large electrical transformer, it is a very important process that the wire joint to be welded must be the arc shape which is a technical requirement to secure the quality of the transformer.

在大型电力变压器制造业的线圈生产车间，一项很重要的工艺要求就是导线接头必须圆弧头焊接，是确保变压器质量的技术要求。

Durable design Water-cooled Anti-collision sensors torch 100 percent contained occasional welding current maximum rate: 300A A high degree of mechanical stability Torch angle: 60 ° Torch Length: 314 mm 3.10.2 torch cable assembly Water-cooled, leather jacket, by the rapid joint connecting wire feeding machine and welding torch.

坚固耐用的设计水冷焊枪防碰撞传感器 100%暂载率最大焊接电流： 300A 高度的机械稳定性焊枪角度：60°焊枪长度：314毫米 3.10.2 焊枪电缆总成水冷式，真皮外套，由快速接头连接送丝机与焊枪。

The effect of each inherent strain component on the angular distortion of the lap joint is studied using inherent strain method.

运用固有应变法研究了六个固有应变分量分别对搭接接头焊接角变形的影响。

The results show that the main cause of the angular distortion of the lap joint is the non-uniform distributed inherent shear strain component that is vertical to the weld line and exists in the plane paralleling to the weld line.

结果表明：搭接接头焊接角变形的产生主要是由焊缝及其附近区域与焊缝平行的平面内垂直于焊缝方向上不均匀分布的固有剪切应变分量引起的。

On the condition of laser welding lap joint composed of dissimilar materials under the same parameters, the weld width was relatively narrow when the galvanized steel for boarding up.

在相同参数下焊接异种板材搭接接头，当具有镀锌层的钢板为上板时，焊缝熔宽较窄。

Due to very short time in welding and the large cooling rate of the joint, the transformation of austenite in the nugget suppresses, and the microstructure of the nugget refines remarkably, the microstructure of HAZ uncharges.

由于储能焊极短的焊接时间和大的冷却速率，熔核中奥氏体组织来不及长大，使得接头组织得到显著细化，热影响区组织未发生明显变化。

All welded joints in stair stringers shall have complete joint penetration welds.

楼梯梁上的所有焊接节点应该有接头焊透层。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
