求翻译：从金相分析的结果我们也可以观察到焊后保温焊接工艺试件的焊缝区组织形态明显比直接焊接焊接工艺试件焊缝区组织形态分布更均匀，晶粒也越小，具有较好的力学性能。是什么意思？

We also can observe from the results of metallographic analysis to the insulation after welding the welding process the specimen morphology of the weld zone was more evenly distributed than welding the welding process the specimen morphology of the weld zone, the smaller the grain, with better mecha

Kim from the results of the analysis we can also observe a warm soldering process after welding the weld area on clear organizational patterns than direct soldering soldering processes on weld area organizational patterns distributed more evenly, and the smaller die also has a fairly good mechanics,

We also may observe from the metallography analysis result after weld keep warm the welding craft test sample welded joint area organization shape to be obviously evener than the direct welding welding craft test sample welded joint area organization shape distribution, the crystal grain is also sma

Metallographic analysis we can observe the results of post weld heat weld zone of welding procedure test piece shape than direct weld zone of welding process of welded specimen forms distribution more uniform, more small grain, which has good mechanical properties.
