Abstract：

The processing and welding technologies for hammer machine were researched, the reasonable hammer forging processing technology which could effectively lower the cost of the imported hammer head was formulated. And the welding was used in repairing the hammer after wearing, which provided the theory basis for the remanufacturing of hammer head. The practice shows that the hammer made in accordance with the processing and welding technology has small cracks after forging about 2000 axles for 13 days, without obvious crack and wear phenomenon, which can meet the production requirements.
