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:

5 Reasons Why Upgrading Your Controls Package is a Smart Idea

Posted by Bob Besse on Aug 5, 2016 6:00:00 AM

Topics: Controls Package

Historically, many manufacturers have been reluctant to change from the familiar machine control systems they have used for decades over fears of incurring high upgrade costs. Despite the escalating price of maintaining a DOS system versus the affordable advantages of a modern Windows driven machine, concerns over the initial cost of switching to new and enhanced control systems have kept old ones in place well past their effectiveness.

Whiteboard Wednesday: Bi-Metallic Friction Welding

Posted by Dan Adams on Jul 13, 2016 6:00:00 AM

Topics: Whiteboard Wednesday

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:

Whiteboard Wednesday: Linear Friction Process

Posted by Dan Adams on Jun 29, 2016 6:00:00 AM

Topics: Whiteboard Wednesday



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:

Topics: Risk Mitigation

As a manufacturer, you know there are many inherent risks in the production process. And one of the biggest is down-time. This is especially true for operators of critical equipment like friction welding machines. Whether your business is growing rapidly, you have production needs while your friction welding machine is being built, or your machine will be off line for scheduled maintenance, you can’t afford to slow down. That’s why MTI has developed a unique approach to keep your business up and running, around the clock.

Whiteboard Wednesday: Hybrid Process

Posted by Dan Adams on Jun 15, 2016 6:00:00 AM

Topics: Whiteboard Wednesday

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.

Topics: Whiteboard Wednesday, Linear Friction Welding

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.
