不可焊接

Inextensible steel reinforcements are either flat ribbed strips or welded wire mats, both of which are hot dip galvanized (except for temporary structures).

不可拉伸的钢筋可以是平的钢筋条，也可以是焊接钢筋网，均经过高温镀锌。

Energy deposition at the interface of the particles caused by micro-explosive welding in explosive consolidation of metal powders is analyzed by symmetrical impaction model of uncompressible liquid. Two-dimensional equation of energy in the flow field of explosive welding is deduced and solved by finite difference method. Then the distribution of the temperature in the flow field is calculated on the basis of considering the adiabatic compression.

摘 要：以不可压缩理想流体对称碰撞模型对金属粉末爆炸烧结中由微爆炸焊接引起的颗粒界面附近沉积的能量进行了分析，在考虑热传导效应的基础上推导出了焊接流场中二维形式的能量方程并用有限差分法对其进行了求解，在考虑冲击绝热压缩贡献的基础上计算出了焊接流场中的温度分布。

Second, and most importantly, many of the strongest aluminum alloys are not weldable using conventional techniques.

第二，也是最重要的一点，很多高强度铝合金不可使用惯用的技术焊接。

The depth of groove resulting from trimming the internal flash of pipe shall not undercut the contour of the pipe by more than 0.4mm according to paragraph 7.8.7 of API 5L specification.

因裁切内部闪光焊接痕迹所致的焊接坡口深度应按 API 5L 中第7.8.7节下所规定的不可超过管道底部边缘0.4毫米。

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 applications field, induction heating apply to melting, fully heating, heat treatment and jointing, and it is a important energy sources in many industries such as metallurgy, national defense, machine-driven industry.

在应用领域方面，感应加热可用于金属熔炼、透热、热处理和焊接等过程，已成为冶金、国防、机械加工等部门及船舶、飞机、汽车等制造业不可缺少的技术。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
