<p><strong>冷焊修正机是利用高频电火花瞬间放电、无热堆焊原理来修正铸件缺点。由于冷焊热影响区域小，不会造成基材退火变形，不产生裂纹、没有硬点、硬化现象。而且熔接强度高，补材与基体同时熔化后的再凝固，结合牢固，可进行磨、铣、锉等加工，致密不脱落。冷焊修正机是修补铝合金气孔、砂眼等细小缺点的理想方法。【铝合金缺点修正】　　铝合金在生产过程中，容易出现缩孔、砂眼、气孔和夹渣等铸造缺点。如何修正铝合金铸件气孔等缺点呢？如果用电焊、氩焊等设备来修补，由于放热量大，容易产生热变形等副作用，无法满足补焊要求。【高度度铝合金】　　高度度铝合金指其抗拉强度大于480兆帕的铝合金，主要是压力加工铝合金中硬铝合金类、超硬铝合金类和铸造合金类。【铸造铝合金】　　铸造铝合金（ZL）按成分中铝以外的主要元素硅、铜、镁、锌分为四类，代号编码分别为100、200、300、400。【铝材】　　铝和铝合金经加工成一定形状的材料统称铝材，包括板材、带材、箔材、管材、棒材、线材、型材等。【压力加工铝合金】　　铝合金压力加工产品分为防锈（LF）、硬质（LY）、锻造（LD）、超硬（LC）、包覆（LB）、特殊（LT）及钎焊（LQ）等七类。常用铝合金材料的状态为退火（M焖火）、硬化（Y）、热轧（R）等三种。【纯铝产品】　　纯铝分冶炼品和压力加工品两类，前者以化学成份Al表示，后者用汉语拼音LG（铝、工业用的）表示。</strong></p>
