There have been considerable efforts towards the realization of ideal floating inductors where mostly three active blocks are required. The reduction in the number of active blocks to two was however achieved with considerable increase in the number of resistances and passive parameter constraints. The proposed scheme suggests a method to produce a floating inductor with a series negative resistance using two current conveyors, only three resistors and one capacitor, involving only one restrictive constraint.

Updated every five years, the AWS D1.1/D1.1M, Structural Welding Code – Steel, is the must-have welding

code for every welder. It spells out the requirements for design, procedures, qualifications, fabrication,

inspection, and repair of steel structures made of tubes, plate, and structural shapes that are subject to either

static of cyclic loading.

    Online Webinar

    11:00 AM - 12:00 PM EDT (8:00 AM - 9:00 AM PDT)
    Turnkey Laser Systems for Part Marking and Batch Processing

    This webinar covers the fundamentals of laser marking. It explains in detail the benefits of flatbed laser plotters for marking a range of different work pieces, and covers galvanometer-scanned (galvo) laser systems for high-speed marking. The presentation will thoroughly examine the benefits and uses of both fiber and CO2 laser systems, and will discuss best practices for part marking and batch processing.

    Marking metals and plastics has become increasingly important for industrial businesses. This webinar will examine the features and benefits of flatbed and galvo systems with an emphasis on fiber laser marking. In addition, Trotec's Flexx concept will be explored. The unique flexx function is the centerpiece of the Speedy flexx Series. With it, CO2 and fiber laser can alternately be activated in a single job, without the need to manually change laser source, lens or focus.

    The presentation will also delve into industry best practices, trends, and new technologies and innovations.

    Key Take-Aways:

    • Learn the fundamentals of laser marking.
    • Understand the features, benefits, and uses of CO2 and fiber laser systems.
    • Discover best practices for high-speed laser marking in high numbers or quick-change parts.
    • Gain information about processing dynamic data and communicating with laser marking systems.
    • Fully understand the design differences and uses of flatbed plotter systems and galvo laser work stations.
