2. What Is Electro-Magnetic Impact Welding ?
Electromagnetic pulse welding is a new and
innovative joining process.
It use of electromagnetic forces for deformation
and joining of workpieces.
Solid State and Lap welding .
High amplitude current require.

6. Research Works
It was found that the most
intensive induced current density
region is at the edge of the
welded zone.
It is also seen that the interface
temperature increased rapidly
around 5o /µs .

7. Advantages
 Joining of conventionally non-weldable materials.
 High production rate possible.
 Contact-free: no marks of forming tools and processing
of coated or sensitive materials is possible.
 MIW is green process. There is no heat, no radiation, no
gas, no smoke and sparks therefore the emissions are
negligible.
 MIW is very suitable for working environment condition
due to a low noise level.

8. Limitations
 Lap joints are required, since one sheet material must
impact the other part to create a weld.
 One of the sheet materials needs to be a good electrical
conductor, otherwise a conductive so-called ‘driver’
material should be used to increase the impact velocity.
 One workpiece has to withstand the impact of the other,
so it is possible that a mandrel or support is required to
prevent deformation.
