本文介绍了为解决物料破碎机板锤的现场不拆卸堆焊问题而研制的焊条及其焊接工艺。应用专门研制的ＺＤ６型焊条，有效地解决了Ｍｎ１３钢可焊性差的难题，延长板锤寿命２倍多。对高锰钢材质的工程机械易损件的表面堆焊修复有参考价值。
This article describes the welding rod and its welding technology developed to solve the problem of the material hammer of hammer mill without disassembly. Application of specially developed ZD6-type electrode, Mn13 steel solves the problem of poor solderability, extend the hammer life of more than 2 times. On the high-manganese steel construction machinery wearing parts of the surface surfacing repair reference value.
