Vacuum diffusion welding of dissimilar materials of M2/40Cr
The technology of friction-stir welding of dissimilar materials of copper (T2) and brass (H62) was investigated.
Some designers use metal strips at the section where the orifices are to be, thus avoiding the difficulties of filing dissimilar materials.
The results shown that a deformation-free joint with good weld surface appearance can be obtained with suitable welding conditions for butt-joint and lap-joint of the dissimilar materials.
