href="http://machine.oecr.com" target="_blank" class="relatedlink">机械</a>化，出产效率高。可是也存在许多疑问，比方无损检测艰难，接头强度低一级。跟着各种焊接办法的不断发生和开展，点焊办法也呈现多元化。当前现已使用于出产的就有电阻点焊、电弧点焊、<a href="http://laser.oecr.com" target="_blank" class="relatedlink">激光</a>点焊和胶接点焊等多种点焊办法 。 <br /> 激光点焊作为一种新的点焊办法，与传统的电阻点焊比较具有其特有的优势。因为选用激光作热源，点焊速度快、精度高，热输入量小，工件变形小；激光的可达性较好，可以削减点焊时方位与布局上的约束；激光点焊归于无触摸焊接，焊点之间的间隔、搭接量等参数的调理规模大；不需要很多的辅佐设备，可以较快的习惯商品改变，满意市场需求。激光点焊所具有的高精度、高柔性的特色使其在实践出产，特别是航空工业的使用中可以替代传统的电阻点焊和铆接等技能。 当前激光点焊技能多使用在大批量自动化出产的细小元件的组焊中，选用高频率、低功率的脉冲激光器，所得焊点热影响区小，焊点无污染，焊接质量高。 <br /> 激光焊点剖析： <br /> 激光焊点外表存在金属堆积，焊点中间则呈现不一样程度的下塌，这主要是因为金属来不及回填发生的。当激光功率到达必定值时，熔池中的液态金属急剧蒸腾构成匙孔，并发生一个反冲力，把液态金属面向熔池的边际，堆积在焊点周围。当激光中止效果时，金属不再蒸腾，反冲力不见，堆积的金属在重力的效果下重填匙孔，一起液态金属冷却凝结。若是金属在没有彻底回填匙孔的情况下凝结，就会在焊点外表构成下塌。相对于接连焊来说，因为激光点焊加热时间短，金属的冷却凝结速度很快，所以下塌表象更显着。别的，在点焊进程中还存在着金属的丢失，这种丢失一方面是因为激光点焊时金属急剧蒸腾，另一方面是金属蒸腾时发生的反冲压力构成金属的飞溅。 在未熔透情况下焊点外表均无下塌表象，且功率改变对熔深的影响较大。焊点彻底熔透，此刻外表呈现显着下塌，甚至在焊点的外表中间构成凹坑，激光功率越大，凹坑表象越显着。气孔表象要比熔透情况下显着。气孔方位一般呈现在熔合面邻近，这可能是因为激光功率较小时熔池的搅动不行剧烈，熔池中的气泡无法很快的上浮，然后构成气孔。 <br /> 离焦量对焊点焊的影响 <br /> 离焦量的改变直接改变了光斑直径与能量密度的巨细，离焦量向负方向和正方向增大时，都意味着光斑直径的增大和能量密度的减小。在激光点焊进程中，光斑直径与激光入射在试件上所构成的初始匙孔巨细存在必定的对应联系，而能量密度则决议了熔池的拓展速度。当离焦量绝对值较小时，激光光斑直径小，激光功率密度大，焊点熔池拓展的速度较快，但初始匙孔的直径小；相反情况下，离焦量较大，初始匙孔的直径大，可是熔池拓展速度变慢，得到的焊点尺度不必定很大，故在离焦量的改变进程傍边光斑直径和焊点外表功率密度的归纳效果决议了焊点尺度的巨细。 <br /> 激光点焊具有的特性： <br /> (1) 跟着激光功率的添加，焊点外表直径呈现上下动摇，熔合面直径和下外表直径添加缓慢。焊点截面形状的改变不显着。而跟着持续时间的添加，焊点尺度添加很快，熔合面直径的改变速率要大于上下外表直径的改变速率。离焦量的改变对焊点尺度的影响很大。它直接改变了光斑直径和激光功率密度，这两者的归纳效果决议焊点尺度的巨细。 <br /> (2) 在熔透情况下，激光点焊的焊点外表存在显着的下塌。跟着激光功率和持续时间的添加，焊点外表的下塌深度增大，在持续时间或许空隙尺度较大的情况下，下外表还会呈现内凹。 <br /> (3) 跟着空隙的添加，焊点全体变形，中间的下塌和内凹都很显着，且熔合面呈现缩短表象，强度降低很快。 当前在焊接电阻、电池及<a href="http://electronic.oecr.com"
