When titanium pieces of sheet material are to be joined by resistance projection welding, the projection should be relatively small in height so that the cycle time can be kept short. If the cycle time is not short, the titanium material will be annealed. The projections 3 should be formed in the thicker piece of material when joining pieces of unequal thickness. This is because the thicker piece 2 requires more heat for a good weld. The electrodes 5 are made from Group A, Class 2 RWMA (Resistance Welder's Manufacturing Association) material where the electrode 5 for the thicker piece of material is faced with Group B, Class 11 RWMA material 6.
