要：概述了铝合金的焊接特性以及焊接过程中的难点,由于铝高反射、导热快的特点,激光焊接也不可避免地存在一般熔焊常遇到的焊缝气孔、焊接热裂纹等问题。鉴于铝合金自身特点,也使激光焊接<a href="http://optics.oecr.com" target="_blank" class="relatedlink">工艺</a>更加复杂,亟待改进和完善。提出了相关改进措施,通过表面处理、改善焊接接头、调整焊接波型参数等来改善铝合金焊接性能。<br /> This paper describes the welding characteristics of aluminum alloy and the difficulties in the welding process. Due to high surface reflectivity and thermal conductivity, welding porosity and hot cracking are inevitably encountered in laser welding process,which makes the laser welding technology more complicated. Thus,a series of solutions are proposed to improve the welding properties of aluminum alloy,such as surface treatment,improvement of welded joints,and adjustment of welding waveform parameters.<br />
