Friction Stir: The Adolescent Years

Friction stir welding has ventured into the age of what I would call, the adolescent years. You know, that age where you see things change from “Dad, would you like the remote” to “Dad, give me the remote”. Those of you with teenagers know what I mean. Friction stir has good traction for most of […]

Hybrid Arc Welding offers High Speed and Low Distortion

Hybrid arc welding pairs two arc welding processes such as GTAW (Gas-Tungsten Arc Welding) and PAW (Plasma Arc Welding), or GMAW-P and PAW. Predominant advantages are high penetration up to 3/8-in (9 mm) with keyhole PAW and simultaneous filling of a small vee groove to weld ½-in or more in a SECB configuration for stainless […]

The Advancement of Ultrasonic Metal Welding Tool Materials

Ultrasonic Metal Welding is a unique process that has typically been limited to applications involving softer, high conductivity alloys. Skipping over the physics and metallurgy of the process; let’s just say that high-frequency vibrations are transferred to the work pieces via a set of ultrasonic tools to create a solid-state bond. For welding softer materials, […]

Product scores big with Electronics Manufacturers

EWI SonicSolder™ is an exciting innovation for wetting materials previously considered to be non-solderable. The binary Sn-Al lead-free solder alloy allows for successful joining of aluminum, copper, titanium, glass, ceramics, and other difficult-to-bond materials. It can be used for both micro-joining and large scale applications, is bio-compatible, and can be readily formed into usable shapes, […]

Cutting Chemical Analysis Testing Time

Soon, EWI will be adding a glow discharge spectroscopy system from Leco® to our lab. The system will give us the ability to perform accurate elemental analysis of common steels, stainless steels, titanium, copper and aluminum alloys. Importantly, having the equipment in-house will reduce our customers’ leadtimes on chemical testing from several days to a few […]

Oil & Gas: In-Service Welding of Super Duplex Stainless Steel

In-service Welding Procedure Development for Super Duplex Stainless Steel in Low Temperature Applications Welding onto anything that contains product at pressure and/or under flow is considered an in-service weld. In-service welding is a common industry practice in both the transmission and refining industry with the vast majority of these welds being deposited onto carbon steel […]
