焊接

Based on the principle of inversion analysis , applications of inversion analysis in welding field including material properties, heat source model, boundary conditions were introduced.

在阐述了反演分析原理的基础上，介绍了国内外焊接领域，包括材料性能，热源模型，边界条件等问题中反演分析的应用，及反演分析各种算法的原理及特点。

This paper mainly introduces the electrical characteristics of the Robot MOSFET Arc Welding Invertor and its arc welding technological properties. Emphases are laid on the analyses of the current and voltage wavefonns of the main circuit as well as the energy loss of the MOSFETs. The different static characteristic curves and parameters of electrical reactance are also discussed.

研究了机器人场效应管式弧焊逆变器的电气性能和弧焊工艺性能，并着重对其逆变主电路电流、电压波形、管组功耗进行分析研究，以及探讨如何采用不同形状的外特性曲线与合理设计电子电抗器的电参数，从而提高弧焊机器人对不同工件开关、不同弧焊方法的适应性，实现贫飞溅的焊接。

Being a roustabout was rated the worst, followed by lumberjack, ironworker, dairy farmer and welder, it said.

最不受欢迎的工作就是码头工人，接着是伐木工、钢铁工、奶农和焊接工。

Down to 2-for-one adapter used, the colors are dim, irregular welding point, it seems to be a real defect.

把换下来的两块转接卡拿来一看，都是颜色暗淡，焊接点极不规则，看来是个真正的次品。

Mrs. Zhou has been engaged in design and manufacture of large-scale irrigator, mini-irrigator and 300MW coal-fired blowing system and manufacture of auxiliary equipment in power station, and has published academic thesis in trade journals like Weldin g and Machinery etc.

Creep tests of P91 base material and its welds have been carried out,the creep behavior of P91 studied and creep rupture strength extrapolated by the Isothermal and the L-M parameter methods,followed by creep life estimations of P91 fresh steam pipes.

对P91钢母材和焊接接头进行持久试验，研究P91钢的蠕变特性，采用等温线法和L-M参数法对持久强度进行外推，进而对P91钢制主蒸汽管道的蠕变寿命进行估算。

This improvement mainly reflected along the rolling direction, so that steel is no longer a certain extent, isotropic body; pouring the bubble was formed, cracks and loose, but also under high temperature and pressure have been welded together.

这种改善主要反映了沿轧制方向，使钢不再是在一定程度上，各向同性体；浇注泡沫形成，裂缝和松动，但在高温高压也被焊接在一起。
