铝镁合金料仓壳体的焊接

摘要

In connection with that welding seam is apt to occure porosity, cracking & deformation on LF2 Al-Mg alloy,the manual tungsten argon arc welding technology was used & a suitable welding procedure was slected and the double side synchronous welding method was taken. Last, a excellent welding seam was aquired.%针对LF2铝镁合金焊接时易产生气孔、裂纹及变形的原因，采 用了能量集中的手工钨极氩弧焊，选择合适的焊接工艺，采用了双面同步施焊等措施，获得 了优良的焊缝。
