摘要
针对4.80 mm厚的2A14-T4铝合金板,通过调节搅拌摩擦焊的焊接参数来改变焊接热输入,研究了焊接热输入对焊缝表面成形的影响。结果表明:下压量、转速和焊接速度等单一焊接参数的改变均会改变焊接热输入;热输入的高低会影响焊缝表面成形,且该热输入存在一个适合的范围,相应得到良好的焊接成形。
The friction stir welding joints were produced in 4.80 mm thick sheets of aluminum alloy 2A14-T4. The welding parameters were changed to investigate the influence of weld heat input on weld bead shaping.The results show that each of welding parameters such as depth of FSW tool, velocity of welding and rotational speed would change the weld heat input. The weld bead shaping is effected by different weld heat inputs. And the weld heat input exhibites a suitable range, which results in a good weld bead shaping.
