class="relatedlink">加工</a>技术，早在1964年就应用在薄小零件的焊接中。今天为大家介绍一下三大激光焊接技术！</div><div><br></div><div> 1.激光钎焊</div><div><br></div><div> 激光钎焊即以激光作热源，利用熔点比母材低的<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>作填充金属(称为钎料)，经加热熔化后，利用液态钎料润湿母材，填充接头间隙并与母材相互扩散，实现连接的焊接方法，其原理如图所示。</div><div><br></div><div> 激光钎焊<a href="http://optics.oecr.com" target="_blank" class="relatedlink">工艺</a>应用于焊接，不仅使<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>更加美观，提高了密封性，而且显著提高了焊接区域的强度，提升了整车的安全性能。</div><div><br></div><div><p style="text-align: center;"><a href="data/attachment/portal/202008/27/172150qys1kttydkrsc6cz.jpg" target="_blank"><img src="data/attachment/portal/202008/27/172150qys1kttydkrsc6cz.jpg"></a></p></div><div><br></div><div> 激光钎焊为目前汽车车身焊接应用广泛的焊接工艺，它的主要优势在于能生成光滑的表面，同时可避免熔化锌镀层。其在车身上多用于以下部位：左右侧围与顶盖接合处(取消车顶橡胶密封条，美观且降低成本);后备箱外板上下两部分的结合;C柱上下两段的结合。</div><div><br></div><div> 2.激光熔化焊</div><div><br></div><div> 激光熔化焊是利用激光为热源，在两板件角接处，各熔化两板件部分母材(同时熔化附近焊丝填充两板件角接处)，使其形成液体金属，待其冷却后，形成可靠连接的一种焊接方法，其工艺原理如图所示。</div><div><br></div><div><p style="text-align: center;"><a href="data/attachment/portal/202008/27/172207fuchtjolwoulcl6l.jpg" target="_blank"><img src="data/attachment/portal/202008/27/172207fuchtjolwoulcl6l.jpg"></a></p></div><div><br></div><div> 激光熔化焊具体可分为激光熔透焊、激光熔焊(不填丝)和激光熔化填丝焊等，多用于汽车顶盖与地板等处的焊接。</div><div><br></div><div> 3.激光远程焊接</div><div><br></div><div> 激光远程焊接是在机器人的第六轴上安装一个振镜扫描头，仅通过镜片摆动反射，实现激光轨迹运动，而无需机器手臂跟随运动。</div><div><br></div><div> 激光远程焊接系统高度柔性化，效率更高，一套系统可取代6～9套普通机器人点焊。激光头与工件距离超过500mm，可延长镜头保护玻璃的使用寿命。</div><div><br></div><div> 与传统的焊接工业相比，激光远程焊接最大的优点在于能够提高生产率，扫描头的快速镜片运动使得用于定位<a href="http://machine.oecr.com" target="_blank" class="relatedlink">机械</a>手的时间大大减少，进而大幅度缩短了制造时间，与电阻点焊平均0.5个焊点/s的速度相比，激光远程焊接的速度为3～4个焊点/s，使激光束得到了充分利用。通过大批量生产<a href="http://opticaltest.oecr.com" target="_blank" class="relatedlink">测试</a>，激光远程焊接同传统的电阻焊接相比，时间缩短了80%。</div><div><br></div><div> 扫描式镜头高灵活性的另一个重要体现是焊接形状的多样性，如果焊缝为C字形，跟线性的焊缝相比，它的焊接速度明显增加。激光远程焊接多用于汽车白车身分总成上，图为激光远程焊接的部分实物。</div><div><br></div><div><p
