Actuators for resistance spot welding (RSW) applications.

New ServoWeld® actuators from Tolomatic are redesigned for higher performance and are lighter weight compared to other screw technologies. Featuring roller screws designed and manufactured by Tolomatic, the ServoWeld actuators are made especially for resistance spot welding (RSW) applications in the automotive industry. The ServoWeld actuators deliver 20 million welds or more, much longer than competing technologies such as ball screws and inverted roller screw actuators, according to Tolomatic.

“We developed the ServoWeld SWA and SWB actuators based on nearly 15 years of experience in the industry, and we understand what it takes to make actuators and roller screws for resistance spot welding applications,” said Bill Graber, ServoWeld global business director, Tolomatic. “The result of our efforts is the broadest line of 7th axis RSW actuator products, which allow our customers to select the right ServoWeld product for their application.”

The ServoWeld Advanced (SWA) actuator is based on the highest level roller screw technology available to deliver the maximum number of welds. The ServoWeld Base (SWB) actuator is built on an alternate roller screw design to provide longer life than typical ball screw and inverted roller screw technology, but at a more economical price than the SWA actuator.

The SWA and SWB ServoWeld models are available in two sizes: a smaller size 3 for lighter-duty weld schedules; and a size 4 for heavier-duty applications. Both sizes are available in a variety of roller screw thread pitches (5mm and 10mm), motor voltages (230Vac & 460Vac) and multiple options for rod ends, feedback & connectors, and water cooling. These models can produce actuator forces at the rod up to 4,000 lbf/17.8 kN, lasting 20+ million welds and holding +- 3% force repeatability over the life of the actuator. Each model comes equipped as standard with a re-lubrication port to easily service the actuator without disassembly from the weld gun to maximize its life.

• Tolomatic has extensive experience in the automotive resistance spot welding industry with its predecessor product, the GSWA ServoWeld actuator. Because of this experience, the ServoWeld SWA and SWB actuators have motor files for seamless robot integration with all the major suppliers including ABB, Comau, Fanuc, Kawasaki, Kuka, Motoman, Nachi and many more.

Stakeless earth ground clamp.

Testing the grounding components of equipment in hard-to-reach spaces, including areas that are indoors or fully paved and do not permit driving auxiliary test stakes, can be dangerous and time-consuming.

With Fluke's® 1630-2 FC Stakeless Earth Ground Clamp, electricians and maintenance technicians can measure earth ground loop resistances indoors/outdoors for multi-grounded systems using only the heavy-duty, dual-clamp jaw, so measurements can be taken quickly and safely without the need to disconnect then reconnect the earth electrode from the system. It also enables the user to access and share data remotely with a team via the Fluke Connect® app.

The clamp automatically records data at pre-set intervals and saves up to 32,760 measurements in memory at the set logging intervals. Its heavy-duty clamp jaw is designed to stay in alignment and calibration even in the harshest industrial environments.

The Fluke1630-2 FC clamp measures earth ground loop resistances for multi-grounded systems using the dual-clamp jaw. This test technique eliminates the dangerous and time-consuming activity of disconnecting parallel grounds, as well as the process of finding suitable locations for auxiliary test stakes. Ground tests can be performed in places that were previously difficult: inside build¬ings, on power pylons or anywhere without access to soil to place auxiliary test stakes. With this test method, a two-process measurement is made around the earth ground wire or bus bar using the specially-designed jaw of the 1630-2 FC clamp. Auxiliary test stakes are not used at all. A known voltage is induced by the source in the clamp, and the current is measured by the sensor in the clamp. The tester auto¬matically determines the earth loop resistance for this section of the earthing system.

The Fluke 1630-2 FC is part of Fluke Connect - a system of more than 40 wireless test tools that communicate via the Fluke Connect app, or Fluke Connect Assets software, a cloud-based solution that gathers measurements to provide a comprehensive view of critical equipment status - allowing technicians to view, record, and share measurements from the clamp in real time via their smartphones or tablets and automatically upload them to Fluke Cloud storage along with tags and the GPS location of assets.

The clamp is also available as a non-Fluke Connect model.

Industrial cybersecurity in the US national strategy.

A Bloomberg LIVE conference in Houston, (TX USA), was addressed by Patrick J. Gouhin, Executive Director and CEO of the International Society of Automation (ISA).  He spoke on the future of cybersecurity in the US oil and gas sector, urged energy executives to take action now to protect their facilities and operations from cyberattack.

ISA's Patrick Gouhin
“Given the increasing number of cyberattacks on oil and gas facilities, the importance of these facilities to the economy and national security, and the fact that there are effective cybersecurity standards for the energy industry available today, the time to act is now—not years in the future,” he emphasised, before an audience of approximately 100 senior technology executives and US government officials.

Gouhin participated in a panel session that examined: the need for solutions that can both prevent a cyberattack from occurring and mitigate the damage if one does occur; and the future of cybersecurity strategies and defenses in the oil and gas industry given the absence of mandated standards and regulations. 

He pointed to ISA’s series of industrial automation and control system (IACS) security standards— adopted internationally as ISA/IEC 62443—as a flexible framework for preventing and limiting potentially devastating cyber damage to the industrial systems and networks used in oil and gas facilities and other critical infrastructure.

Developed by leading international cybersecurity experts from industry, government and academia, ISA/IEC 62443 addresses industrial cybersecurity vulnerabilities across all key industry sectors and is regarded as the world’s only consensus-based series of IACS security standards.

IACS, such as supervisory control and data acquisition systems (SCADA), are relied upon to monitor and control the operation of industrial machinery and associated devices. Because most IACS are not designed to ensure resilience against cyberwarfare, an IACS cyberattack can impair and disable safe operations of industrial facilities. The consequences—which can include plant shutdowns, widespread power blackouts, explosions, chemical leaks and more—can place national and economic security as well as lives, personal safety and the environment at risk.

ISA/IEC 62443 enables owners and operators of critical infrastructure to achieve and maintain IACS security improvements through a lifecycle that integrates design, implementation, monitoring and continuous improvement.

ISA’s expertise in industrial cybersecurity standards has been honed through experience. Gouhin pointed out that ISA has been developing industry standards for more than 67 years, with 150 different standards in its portfolio, representing the knowledge of more than 4,000 industry experts worldwide.

Aiding US voluntary plan.
He explained that while the US does not legally require implementation of industrial cybersecurity standards and best practices, the government has developed a voluntary plan to follow. The plan, known as the US Cybersecurity Framework, serves as a how-to guide for American industry and operators and owners of critical infrastructure to strengthen their cyber defenses.

Representatives of both ISA and its affiliate, the Automation Federation, served as expert consultants to the US National Institute of Standards and Technology (NIST)—an agency of the US Department of Commerce—as it coordinated the development of the framework. The ISA/IEC 62443 series of IACS security standards are key components of the framework recommendations, which were made public in early 2014.

ISA’s leadership in industrial cybersecurity also prompted the US Army National Guard to select ISA as an industry partner. Last year, ISA provided control systems security training at the National Guard’s Cyber Shield 2016 exercise at Camp Atterbury, Indiana. More than 900 soldiers, airmen, Marines, sailors and civilians representing 47 states and territories participated at the event to assess their skills in responding to cyber-incidents on the National Guard computer network.

Furthermore, the Automation Federation is the host organization for the LOGIIC (Linking Oil and Gas Industry to Improve Cybersecurity) Program, an ongoing collaboration of major oil and natural gas companies and the US Department of Homeland Security, Science and Technology Directorate. LOGIIC undertakes collaborative research and development projects to improve the level of cybersecurity in critical systems of interest to the oil and natural gas sector.
