It will not annealing the casting to keep the mechanical structure unchanged. The pressure applied to the pieces of metal breaks up the oxide layers and allows the two pieces of material to stick to one another. With increasing compaction temperature the contact surfaces between the powder particles Figure 1111 become smoother and the powder particles are deformed more severely and warm.
You can use a hand-operated cold welding machine for smaller diameter wires and pneumatically or electric cum pneumatically operated.
