pool
(c) Velocity distribution along the welding direction of the
upper surface of the weld pool
(d) Velocity distribution in the vertical welding direction of
the upper surface of the weld pool
(e) Absolute value distribution of the velocity on the upper
surface of the weld pool
(f) Pressure distribution on the upper surface of the weld pool
(g) Velocity vector of the cross section of the weld pool
(h) Velocity vector and temperature distribution of
longitudinal section of the weld pool
