Flowing behaviors affected by different parameters and multi-materials in GTA weld pool hybrid a longitudinal electromagnetic field

摘要

The LMF quells the molten metal motion on the direction of depth, increases the radial motion and the velocity near the surface of weld pool. The surface tension coefficient can change the flowing direction. The increased magnetic induction can hold the flowing velocity of molten metal on the ROZ plane. The lCrl8Ni9Ti stainless steel has the highest flowing and stirring velocity due to the thermal physical properties in the material.
