We have had recent interest in looking at methods to join thermoplastics and thermoset composites to titanium from both the aerospace and medical communities. Generally, thermoset composites have higher temperature resistance than thermoplastic materials and must be bonded because they do not melt. Thermoplastic materials are easier to mold and will flow when heated. Therefore […]
Read MoreA few years ago, I wrote about the excitement of a new toy here at EWI. Since then, we’ve gotten several other new toys, but not one as close to my heart as the baby we just unwrapped! EWI recently took possession of a new Harms and Wende RPS100-K12 RFSSW machine! Woohoo! You have no idea […]
Read MoreProper laser eyewear is required whenever a laser is operated in the open. “Open” means the laser beam is exposed and could make contact with humans nearby. Even at low power, lasers can cause serious eye damage. The laser safety officer will determine what type of laser eyewear is required to protect those that need […]

Read MoreFriction Stir Welding (FSW) is an advanced welding process that uses a third body (often called the “tool” or “pin”) to generate frictional heat between two parts to create a solid-state bond. Originally developed for thin sheet aluminum, the process has now been adapted for a variety of materials from soft metals (aluminum, copper, magnesium, lead) to […]

Read MoreFor decades, the primary joining process used in assembly of electronic components has been soldering. Low-cost equipment and easy training for assembly personnel are two advantages. Repairability and ease of visual quality inspection of soldered joints are others. However, more rigorous usage of components, ranging from medical electronics to military weapons systems, can challenge the […]
Read MoreFrom Webster: fric•tion: the rubbing of one body against another; the force that resists relative motion between two bodies in contact. Engineers in almost every field work to avoid friction by use of proper design techniques or by applying oils and lubricants. We’ve all seen the TV commercials talking about how a certain oil product […]
Read MoreMaterials that cannot be welded must be joined with mechanical fasteners, solder, braze, or adhesives. For extended service above 450oF, a solder or braze is required. At lower operating temperatures, adhesive bonding is used. Adhesives can bond many diverse material combinations and offer the best approach for joining dissimilar materials in corrosive environments. Fasteners, brazes, […]
