鋁和鋁合金經(jīng)加工成一定形狀的材料統(tǒng)稱鋁材,包括板材,、帶材,、箔材、管材,、棒材、線材,、型材等,。缺陷修復(fù)鋁合金在生產(chǎn)過程中,容易出現(xiàn)縮孔,、砂眼,、氣孔和夾渣等鑄造缺陷。如何修復(fù)鋁合金鑄件氣孔等缺陷呢,?如果用電焊,、氬焊等設(shè)備來(lái)修補(bǔ),由于放熱量大,,容易產(chǎn)生熱變形等副作用,,無(wú)法滿足補(bǔ)焊要求。冷焊修復(fù)機(jī)是利用高頻電火花瞬間放電,、無(wú)熱堆焊原理來(lái)修復(fù)鑄件缺陷,。由于冷焊熱影響區(qū)域小,不會(huì)造成基材退火變形,,不產(chǎn)生裂紋,、沒有硬點(diǎn)、硬化現(xiàn)象,。而且熔接強(qiáng)度高,,補(bǔ)材與基體同時(shí)熔化后的再凝固,結(jié)合牢固,,可進(jìn)行磨,、銑、銼等加工,致密不脫落,。冷焊修復(fù)機(jī)是修補(bǔ)鋁合金氣孔,、砂眼等細(xì)小缺陷的理想方法。
