Connecting of doubler strake is a relatively weak link, fatigue strength of which is largely reduced due to the influence of the weld flaw, weld inside stress and weld surface figure. If the ship is under the alternate load function for a long time in long service, fatigue destruction of connecting may happen, strength of deck plating or bottom plating strengthened may also be influenced.

复板条的对接接头是一个相对薄弱的环节，由于焊缝缺陷、焊接内应力、焊缝表面形状等因素的影响，使得接头的疲劳强度大幅度降低，船舶在营运过程中长期受到交变载荷的作用，就会引起对接接头的疲劳破坏，继而影响到被加强的甲板或船底板。

Using oxygen ethine flame spraying weld technology,taking Ni base alloy powder Ni O2C as material of spraying weld layer,the spraying weld prestrengthening to the sealing chute of No.

采用氧一乙炔火焰喷焊工艺，选择镍基合金粉末 Ni-O2 C作为喷焊层材料，对莱钢烧结厂 1#烧结机密封滑道，进行喷焊预强化，解决了高温烟气冲蚀和磨粒磨损问题。

But for the TEC overmatching, the residual stress σ〓 in the weld center is also related with the strain hardening coefficient H W of the weld metal. The residual stress σ〓 in the weld center got to the yield strength σ〓 increases little when the H'w is lower and somewhat exceeds the σ〓 when the H'w is higher.

而高胀匹配时的焊缝中心纵向残余应力σ〓还与焊缝金属应变硬化指数H〓有关，H〓较低时，焊缝中心纵向残余应力σ〓在达到焊缝金属屈服强度σ〓后不再升高；H〓较高时，焊缝中心纵向残余应力σ〓可超过焊缝金属屈服强度σ〓。
