1.操作簡(jiǎn)單,一機(jī)多用,除修復(fù)功能還可進(jìn)行碳化鎢等硬質(zhì)合金表面涂層強(qiáng)化。                                                                                                                   

2. 氬氣保護(hù)密著性好，熔接強(qiáng)度高，冶金結(jié)合，補(bǔ)材與基體同時(shí)熔化后的再凝固，結(jié)合牢固、致密、不脫落                                                   

3. 低熱輸入, 常溫焊補(bǔ)，基體不發(fā)熱，焊補(bǔ)點(diǎn)附近金相組織不變無應(yīng)力，無裂紋，無硬點(diǎn)硬化現(xiàn)象, 不影響機(jī)械加工性能.                                                      

4. 電極來源廣,經(jīng)濟(jì)實(shí)用,可在線修補(bǔ).                                       

5. 旋轉(zhuǎn)式自損電極沉積堆焊，操作容易，工作效率高.
