Abstract
The thin sections and residual porosity typical of metal injection moulded (MIM) components pose challenges when using welding as a joining technology, but if welding can be successfully applied the potential commercial benefits are considerable. Process development of gas tungsten arc (GTA) welding for MIM parts to tubing and wrought components are described and the suitability of MIM 316L products in welded applications, particularly fluid system components, is discussed.
