The results showed that the fracture toughness of the weld of HFW pipe was lowest.The value of absorbed energy of HFW weld was closely related to the heat treatment process.But the fracture toughness of fusion zone of submerged-arc welded jointer,its microstructure was coarse granular bainite,and was lower than the other locations of heat affected zone;and with the increasing of steel strength,the effect of welding heat cycles on the pipeline steel became stronger,and form coarse microstructure in fusion zone leading to decrease fracture toughness.

结果表明，高钢级管线钢高频焊接焊缝处的断裂韧性最低，其冲击功大小与热处理工艺密切相关；而埋弧焊接热影响区断裂韧性在熔合线处最低，其主要原因是此处的组织为粗大的粒状贝氏体，而且强度越高焊接热循环对管线钢的作用越强，在熔合线附近更容易产生粗大组织，使断裂韧性降低。

I plant to set up a powerful installation and technical guidance team, the introduction of the German production of Lucerne stroke grid welding machine, welding machine Socket, MUNSCH extrusion type welder and Switzerland Nissan LEISTER hot air welding machine, equipped with more than 30 professional welding holder staff, received the company ROCHLING training, professional services engaged in welding works.

我厂成立了强大的安装与技术指导队伍，引进德国罗森搏格产对焊机、承口焊接机、MUNSCH挤出式焊机及瑞士产LEISTER热风焊机，配有30余家持证专业焊接人员，得到ROCHLING公司培训，专业从事焊接施工服务。

In addition, effects of weld heat input on microstructure and performance of the weldjoints are analyzed. The test results indicate that by controlling weld heat input about 16kJ/cm and practicingmulti-layer weld process, the coarse austenitic grains in the weld metal and lumpish ferrite in the heat affectedzone can be avoided so that the microstructure and performance of the weld joints can be ensured.

结果表明，采用多道焊焊接工艺，严格控制焊接线能量在16 kJ/cm左右，可以防止T91钢焊缝区奥氏体晶粒粗大，避免在热影响区出现块状铁素体组织，从而保证焊接接头区具有良好的组织性能。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
