The parent material has certain grain sizes in the pre-welded material. The mechanical and thermal working of the material affects the grain size and orientation. This grain refinement process can improve the mechanical properties at the weld interface and in some cases, results in a stronger, more reliable material. In other cases, the refined grained material can be restored through post-weld thermal processing.
If you take a magnified look at a weld section from a typical Rotary friction weld, you would see a reduction in the grain size near the weld zone. As you move further away from the weld zone, the grain size slowly increases back to the original parent material.
This is important because friction welding allows you to make a part that is the quality of a two-piece forging and get parent material properties as a result.
You Can Depend on MTI Quality
Don’t cut corners with low-quality parts to save money. MTI specializes in producing the highest quality parts from a wide variety of cost-effective materials and has the knowledge and ability to do so quickly and affordably. We’ll build a machine that makes your part, we’ll make the part for you, or we’ll help you make the part even better.
