Where filler materials having tensile properties deviating (downwards) from the parent metal are used, this fact must be taken into account when dimensioning the weld joints.
从母材部分开始使用具有伸缩性的填角材料之处，计算焊缝时应该考虑到这种情况。
The influences of the filler metal powder on the laser power density threshold value, weld formation and process stability were studied during CO_2 laser welding of aluminum alloy.
研究了填充合金粉对CO_2激光焊接功率阈值、焊缝成形和焊接过程稳定性的影响。
Shrinkage small, directional, high incidence of adverse Weld, deformation, warping, shrinkage cracks and stress concentration, resin filler uneven.
收缩小，有方向性，易发生熔接不良，变形、翘曲、缩孔、裂纹及应力集中，树脂填料分布不匀。
