Forgings offer more consistent, better metallurgical properties. Selective heating and non-uniform cooling that occur in welding can yield undesirable metallurgical properties such as inconsistent grain structure. When in use, a welded seam may act as a notch that can contribute to part failure. Forgings have no internal voids that might cause unexpected failure under stress or impact.

orgings offer simplified production. Welding and mechanical fastening require careful selection of joining materials, fastening types and sizes, and close monitoring of tightening practices both of which increase production costs. Forging simplifies production and ensures better quality and consistency.

Forgings also offer cost-effective designs. A multiple-component welded assembly cannot match the cost-savings gained from a properly designed, one-piece forging. Such part consolidations can result in considerable cost savings. In addition, weldments require costly inspection procedures, especially for highly stressed components. Forgings do not.
