<正>The forces acting on a gas tungsten arc(GTA)weld pool are analyzed.A model of static force condition for fally- penetrated weld pool is developed,and the cr
This paper investigates the distribution of contact resistance of the aluminum alloy in the squeeze stage. A new method of measuring path’s resistance is propo
Vacuum brazing experiments of Cf/C composites were carried out using pure Al and Al-5Ti-B as brazing fillers,and shearing strength of the joints was measured.Th
