On the Explosive Welding Characteristics of Steel-Titanium Dissimilar Materials Using finite Element Method Kim, Chung-Kyun; Kim, Myung-Koo; Sim, Sang-Han; Moon, Jeong-Gi;
Using the two-dimensional hydrocode HI-DYNA2D, a calculation on the explosive selding of dissimilar plates(Steel Titanium) was made for the pressure, temperature, velocity and impact ingles adjacent to the collision point during the welding process. The FEM result indicates that optimal stand-off distance of initially parallel set-up is 3-5mm for various values of the explosive thickness. The calculation shows that when the explosive thickness is around 30mm, the temperature of welding point which is strongly related to the metallic jet formation is 2, 000-3, 500K for the given stand-off distance.
