class="relatedlink">激光</a>焊接基本原理可以从激光照射与吸收、熔池形成与凝固、焊缝形成与性能三个方面进行解读。</div><div><br></div><div> 激光照射与吸收是激光焊接最基本的环节，它是影响焊接过程和结果最主要的因素之一。激光照射是使用特定的设备将激光集中到焊接工件的表面，而吸收则是工件对激光光束的反应。</div><div><br></div><div> 一般来说，对于同一种<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>，吸收的光能并非完全一样，因为材料本身的<a href="http://theory.oecr.com" target="_blank" class="relatedlink">物理</a>性质、表面状态、射入角等多种因素的变化均会影响吸收的效果。激光照射的功率、时间和区域都会影响吸收能量的大小和分布，而这又直接决定了焊接产生的熔池的形状和大小。</div><div><br></div><div> 应当指出，吸收能量的大小能影响熔池的温度，而熔池的温度直接关系到焊接结果的好坏。因此，我们在激光焊接过程中，需要严格掌握激光照射的参数，以保证熔池的形成与凝固过程得到有效控制。</div><div><br></div><div> 焊缝形成与性能是激光焊接的最终目标，是对焊接质量的直接评价。焊缝的形状、粗细和全貌，以及对焊接痕迹的痕迹分布、连续性和均匀性等诸多因素，都会对焊接质量造成影响。具有良好的焊缝质量，是激光焊接技术追求的终极目标。</div><div><br></div><div> 焊缝的形成过程是复杂的，包括熔池的凝固、焊岀的炼化、熔池的固化等环节，而这些环节又与激光的功率、焊接速度、焊接材料、环境的温度和湿度等多因素有关。</div><div><br></div><div> 焊缝的性能包括强度、韧性、硬度、耐磨性、耐腐蚀性等方面，这些性能的优劣，是衡量焊接<a href="http://optics.oecr.com" target="_blank" class="relatedlink">工艺</a>水平的重要标准。</div><div><br></div><div> 对焊缝形成过程的理解和掌握，以及对焊缝性能的评价和优化，不仅能提高焊接质量，提高焊接效率，还能为开发新的焊接方法、提高已有焊接方法的效果和范围提供<a href="http://theory.oecr.com" target="_blank" class="relatedlink">理论</a>依据。</div><div><br></div><div> 因此，研究焊缝的形成和性能，对于激光焊接研究和应用具有重要的意义。</div><div><br></div><div><p style="word-wrap: normal; margin: 0px; padding: 0px; color: rgb(143, 143, 143);
