Why Polypropylene Cannot Be Welded with ABS

Why Polypropylene Cannot Be Welded with ABS In order for two materials to weld, there are three main requirements. The materials must be chemically compatible (i.e. the polymer chains must be able to form secondary bonds). Some plastics are compatible this way, however it is mostly different types of amorphous plastics that are compatible with […]

Joining of Steel to Titanium with Interlayers — New Paper

As manufacturers turn to multi-material designs to meet the ever-growing demands on their products, many are faced with the challenge of how to join dissimilar materials. Using traditional joining techniques, metallurgical incompatibilities of certain material combinations have greatly limited the performance and viability of many dissimilar joints. In order to achieve maximum performance from a […]

Microjoining—Meeting big challenges on a small scale

Manufacturing electronic devices with materials only microns in thickness is no small task. Due to the challenges that come with the miniaturization of these devices and their components—the joining of dissimilar, often delicate materials, for example—it is crucial to develop joining processes that are reliable and repeatable. Each application calls for a different approach, and […]

Should you Solder it or Braze it?

We receive  many questions about the difference between soldering and brazing.  They are very similar joining techniques, both involving the melting of a filler metal to join two or more components without melting the base material of the components.  The American Welding Society (AWS) defines brazing as such a process which involves a filler metal […]

Making micro-scale wire welds

When most people hear the word “welding” they think of the guy in the local garage with an arc welder and a mask, or the army of spot welding robots used to build a car body.  You might be surprised to learn that there are many more welds in the sensors and motors in a […]

Ultrasonic Additive Manufacturing presentation at ASM Symposium

Below are highlights from Mark Norfolk’s presentation on Ultrasonic Additive Manufacturing (UAM) a few days ago at the ASM Symposium at GE’s Global Research Center in NY. Mark is a senior project manager at EWI and the CEO of Fabrisonic, an EWI spinout. Ultrasonic additive manufacturing (UAM) is a novel new process that produces true metallurgical bonds with full […]
