在此基础上研制了高韧性、超低氢及操作工艺性优良的、适用于屈服极限为400～450N／mm2级的低合金钢用J557GR高韧性焊条。

The welding wire thus obtained a weld containing not more than 5 ml of diffusible hydrogen per 100 g deposited metal.

这样得到的焊丝形成的焊件每100g熔敷金属含有不超过5ml的扩散氢。

This paper investigated the ultrasonic test on the weld ed strength of Aluminum-steel compound material formed by dynamistic welding. Its strength used to be tested by destructive "mechanics performance test".

对于爆破焊接成型的铝-钢复合材料，其强度测试过去主要依赖于破坏性的&力学性能测试&，现在采用超声波检测其焊接强度，文中对此进行了探讨。

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

The third, fine grains are found along the edge of the weld, which is different from the equiaxial dendritic. Its formation has a relationship with the effect of Li, Sc, Zr, Ti on the crystallization of molten pool.

3.2195铝锂合金焊缝边缘存在独特的细晶层组织，其形态与等轴树枝晶不同，这一特征组织的形成与合金元素Li、Sc、Zr和Ti对熔池结晶过程的作用规律有关。

When the Al-Mg-Zr-Sc welding wire was used as filling material, the grains of welding seam were refined obviously, and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone.

结果表明：采用两种焊丝焊接的Al-Mg-Sc合金薄板的焊接接头强度系数均大于0.9。

When the Al-Mg-Zr-Sc welding wire was used as filling material,the grains of welding seam were refined obviously,and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone .

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。
