Whiteboard Wednesday: Upset Control and Pressure Modulation with Dynamic Profile Modification

In friction welding, we always strive toward repeatability—even when there are differences in the length of incoming parts.  This is especially true in the automotive and aerospace industry where finished parts are held to rigid standards.  Using Torque Modulation with Dynamic Profile Modification, we’re able to ensure our first welded part is the same length as our last welded part.

Over the course of this series on upset control, we’ve discussed the repeatability of upset control and part variation in rotary friction welding. Remember, upset is the amount of shortening you get in the part as a result of friction welding.  Upset is different than overall length, which is the total length of the part after welding.

In Part One of this series, we talked about how upset is the amount of shortening of a part resulting from friction welding. Remember, if we had perfect incoming parts then we could fix the amount of energy used to make that weld, and get very repeatable upset. However, incoming parts variations such as area differences, surface conditions, material differences, or even interface “squareness” can cause subtle variations in upset.

Whiteboard Wednesday: Friction Welding Flash

Posted by Dan Adams on Aug 10, 2016 6:00:00 AM

Topics: Whiteboard Wednesday

During the friction welding process, the combination of heat and force applied between two parts produces more than just a solid-state weld. One of the most notable results of the process is the formation of flash.

As two parts are heated and the material at the weld interface softens, the excess material starts to extrude away from the weld interface. That extruded material is called flash. Flash formation varies from part to part due to shape, type of friction welding process, and the material used. Here are a few common variations:

Whiteboard Wednesday: Bi-Metallic Friction Welding

Topics: Whiteboard Wednesday, Bi-Metallic

One of the key differentiators between friction welding and other welding techniques is the ability to join dissimilar metals or two different materials that may be impossible to join by other techniques. Doing so is a cost effective way of getting the benefits from both materials. Typically we can use any of the friction welding technologies to weld dissimilar metals, and the following are some common bi-metallic combinations and applications:

Linear friction welding is similar to direct drive rotary friction welding since both are a constant energy input process. But unlike rotary, linear friction welding uses linear oscillation (a repeated back and forth motion) to create a solid state weld. There are two components of the oscillation that drives the energy input:

Whiteboard Wednesday: Hybrid Process

The hybrid friction welding cycle is a type of rotary friction welding, and is a combination of the direct drive process and the inertia process.  The direct drive process has a constant energy input using an electric motor. The inertia friction welding cycle, on the other hand, has rotating flywheels that store the energy needed for the weld, which makes it a fixed energy cycle. Hybrid friction welding is a combination of both.

Linear friction welding is a solid-state joining process that uses relative motion and high force in order to create enough heat to create a two-piece forging. In linear friction welding, one part is moved back and forth rapidly in a linear reciprocating motion while the other part is forced into it, creating enough heat between the two parts to forge them together.

Rotary friction welding is a flexible technique that can provide many advantages over traditional fusion welding processes. In order to use the rotary friction welding process, you must have one part that is symmetric around its rotating axis. The non-rotating component, can also be symmetrical but does not have to be.

There are three main types of rotary friction welding—Inertia, direct drive and hybrid friction welding. Each technique offers a unique advantage depending upon the type of materials being welded as well as the shape or geometries of the materials. Let’s take a look at some application examples.

In rotary friction welding, a weld is created by rotating one part while keeping the other part still and applying the right amount of force between the two materials. Not only does this process quickly and efficiently bond two parts together into one, but it also creates what is known as grain refinement, which makes the new part just as strong as a single solid part.

You may not realize it, but friction welded parts are part of your everyday life.  A good example of an everyday application of friction welding can be found in a component used with automobile air bag inflators. This component is found in steering , wheels, glove boxes, dash boards, seats, and side panels, and since every car needs air bags, this component has a very high volume demand. The tricky part is that, due to the intricacy of the specific component shown in the video, it could not be made from a single piece.
