ESAB Introduces Non-Copper-Coated Welding Wires

The latest ESAB OK Aristorod non-copper-coated welding wires are designed to offer improvements in productivity and quality, meaning users can cut the cost of manual, mechanised or robotic welding. OK Aristorod wires are available in 15 grades for use with normal-strength, high-strength, creep-resistant and weather-resistant steels. Customers also have a broad choice of wire diameters. Featuring ESAB's Advanced Surface Characteristics (ASC) techology, OK Aristorod resists corrosion during storage and handling.

It also avoids the problems associated with copper coatings - such as build-ups on feed units, liners and guns. Tip wear with OK Aristorod is as low as that experienced with copper-coated wires and the feeding force is low. OK Aristorod is said to be very welder friendly, producing a stable arc that results in increased welding speeds and high-quality welds with almost no spatter. These characteristics are intended to enhance productivity and quality while also reducing the need for rework and post-weld cleaning.

A further advantage of the non-copper-coated wires is that they produce fewer fumes, meaning that the working environment stays cleaner. One of the reasons behind the higher productivity achievable with OK Aristorod is its ability to operate with higher currents, according to the company. In addition, ESAB's Swift Arc Transfer (SAT) MAG welding process enables OK Aristorod to be used at even higher wire feed speeds and arc voltages to produce flat welds with good penetration and no undercuts. OK Aristorod is available on adapter-free spools or in Marathon Pac 250kg and 475kg bulk drums.

congatec Future-Proofs ETX and XTX Standard

Image
congatec AG, a leading manufacturer of embedded computer modules, is giving the ETX and XTX form factors a viable future with the integration of AMD Fusion technology. Modules based on AMD Fusion processors deliver significant improvements with regard to performance and scalability. Intel’s discontinuation of the 855 chipset family left a major gap in the market particularly for ETX computer modules, which primarily affected the higher performance range of applications. This gap has now been closed by processor manufacturer AMD with the Fusion architecture. Fusion also opens up new perspectives for a wide range of innovative and graphics-oriented applications.congatec has integrated the AMD Fusion architecture into its product range of ETX and XTX COM modules, opening up new scalability options for this form factor to meet even the most demanding tasks. The company supports the Fusion architecture with two new COM modules: conga-EAF and conga-XAF. While conga-EAF is an ETX module, co...

Haydon Kerk Motion Solutions Releases 36mm Linear Actuator Configuration that Replaces Existing 42mm Packages

Image
Haydon Kerk Motion Solutions, a premier manufacturer of linear motion products, has released a new version of its popular 36mm G4 linear actuator. This new configuration includes a special adapter plate that allows the smaller 36mm OD unit to replace 42mm and 46mm units in existing applications. Performance of the 36mm G4 linear actuator not only exceeds the performance of comparable size actuators, it approaches the performance of larger 42mm and 46mm linear actuators from various manufacturers. The 36mm unit with the integrated adapter plate allows users to replace existing 42 and 46mm units easily by using the same bolt pattern and pilot surface. Among the advantages of substituting the 36mm G4 linear actuator include a smaller linear actuator body, which is especially important when space is a premium, and a lower cost system, compared with the larger-size units. With the G4 linear actuator, both can be accomplished without sacrificing performance or lifespan. Force output rang...
