In order know the size and the distribution of residual stresses of mill welding seam,this paper uses blind-hole method to test the girth weld s between round plate and the cylinder body of the mill produced by CBMI CONSTRUCTION CO.

为了了解滑履磨机焊缝残余应力的大小和分布规律，该文应用盲孔法对中材建设有限公司生产的某型号磨机的圆平板与圆筒体之间的环焊缝及其近缝区的表面残余应力进行了现场测试。

In view of easy fusion flaw between connecting of doubler strake and deck plating or bottom plating strengthened, this paper puts forward a fire-new welding technics for the purpose to improve the technics of welding connecting of doubler strake. Under the help of this way, connecting of doubler strake can be penetratingly fillet welded, but not fuse with deck plating or bottom plating strengthened, at the same time the figure of weld surface can also be managed for increasing fatigue strength of connecting.

本文针对复板条对接接头容易和被加强的甲板或船底板发生粘连的缺点，从改善复板条对接接头的工艺入手，提出了新的焊接工艺，使得复板条对接接头既能保证完全焊透，又不会和被加强的甲板或船底板发生粘连，同时对焊缝表面形状进行处理，以提高接头的疲劳强度。

But it has some shortcomings. Connecting weld of doubler strake is directly welded on plating strengthened, in this way welding fluid fuse with plating strengthened such as deck plating or bottom plating, and then connecting of doubler strake fuse with deck plating or bottom plating strengthen. So breakage like crack of connecting of doubler strake may immediately destroy deck plating or bottom plating strengthened, which became of navigational accident.

但是，增设复板条来提高船舶总纵强度的方法有其缺点，每段复板条之间的对接焊缝是直接在被加强的板上施焊，焊缝就会溶入被加强的甲板或船底板，使得复板条对接接头与被加强的甲板或船底板发生粘连，这样，复板条对接接头的开裂等破坏就会直接引起船舶被加强的甲板或船底板的破坏，从而导致海难事故。
