摘要
提出用锤击焊缝的方法消除磨煤机端盖裂纹补焊后的变形,并且示出锤击焊缝前后其高度变化的差值(焊缝减薄量)与焊接变形的关系.为现场修复磨煤机端盖裂纹提供了依据.
To eliminate dLstortion after repair welding for cracks on end cover of coal grinding mill by penning is indicated. The changing in the value of bead height before and after penning in relation to weld dLstortion is presented. The results obtained provide the basis for repair cracks of end covers in sitewelding.
