This paper using the FEM software Marc, for the 50 and 60 degree V groove of flat plate butt joint simulate the one-layer and three layers welding, finish each welding and cooling it down to room-temperature then start the next welding true represent process and get the temperature field, residual deformation and welding residual stress, according to the theory analysis and empirical equation verified the temperature field and residual deformation all correct, comparison with experiment verified the welding residual stress regularity and correctly.

本文利用有限元软件Marc，对开60°和50°V型坡口的平板对接接头，动态的模拟了单层单道打底焊，焊完一道后让试件冷却到室温以及单层单道满焊，每焊完一道后让试件冷却，然后再焊下一焊道，道间温度≤200℃，在以此为初始边界条件下开始下一道的焊接，真实的再现了焊接过程，得出了温度场，残余变形和残余应力场的分布规律，根据理论分析及经验公式验证了温度场以及残余变形的正确性，角变形的大小，这些结果与数值计算相吻合。通过与实验测得的残余应力进行比较，验证了焊接残余应力的分布规律及模拟的正确性。

To get a property comparison of GXHJ－ 1 sintered welding agent with SJ101 sintered welding agent, related tests were carried out, including deposited metal test, lab butt－ joint plate test, single－ welding stick operation test, double－ welding stick operation test as well as operation test with H08C welding stick, focusing differences of the two in terms of technological properties and weld seam impact toughness.

为了比较 GXHJ－ 1和 SJ101两种烧结焊剂的性能，分别从熔敷金属性能试验、实验室对接板试验、单丝焊生产、双丝焊生产等方面及在匹配 H08C焊丝的条件下进行了工艺性能和焊缝冲击韧性对比。

Such as the 12mm plate butt welded flat bottom closure φ3.2mm the electrode selection, welding current :80-85A, filling, cover the surface layer of the electrode selection φ4.0mm, welding current :165-175A, a reasonable choice welding current and electrode diameter, easy to control bath temperature, is the basis for forming weld.

如12mm平板对接平焊的封底层选用φ3.2mm的焊条，焊接电流：80-85A，填充，盖面层选用φ4.0mm的焊条，焊接电流：165-175A，合理选择焊接电流与焊条直径，易于控制熔池温度，是焊缝成形的基础。

It is not susceptible to lethal yellowing disease but is vulnerable to gandorma butt rot; a new disease that has cropped up in Florida palms and has no treatment.

这不是容易致命的疾病，但易泛黄腐烂gandorma对接；一种新的疾病，又冒出佛州棕榈、没有治理。

As you remove the few branches that need removed, look for signs of past problems, nutritional deficiencies, and diseases such as Lethal Yellowing and Ganoderma Butt Rot.

正如你删除几个分公司，需要拆除的迹象，过去找问题、营养缺乏、而致命的疾病，如灵芝、黄腐对接。

It didnt hurt and it was only her right tom,, but just as my pants came down a few girls at my shcool walked in the bathroom and saw my butt cheeks!

它didn't伤害，而只是她的右汤姆，，但正如我的裤子下来几个女孩，我整合走在浴室看到我的对接脸颊！

First, the mismatching factors of submerged arc welding and shielded metal arc welding of S355ML steel (65mm thickness) were determined with "direct measurement method". Then, the butt welds of SAW and SMAW were made to full thickness fracture toughness specimens and the fracture toughness in welds centre were measured by CTOD test.

用&直接测量法&确定了低合金高强钢S355ML钢板（厚65mm）自动埋弧焊和手工电弧焊的焊缝强度匹配系数，同时将这两项焊接工艺的对接焊缝制成全厚度断裂韧度试样，运用裂纹尖端张开位移试验方法测定其焊缝中心的断裂韧度。
