aid of a vacuum is far less porous than other cast metals, so welds and heat treatments are far less likely to cause blistering or other defects. Another application of vacuum die casting is in the aerospace industry, where highly accurate parts with predictable mechanical properties are required...
Robotic welding can be used in any industry that would benefit from automation. Generally speaking, it would be more work than it is worth to program the welding sequence for one weldment. However, there are cases where automation, since it can produce near-perfect welds, will be necessary du...
