The Revised ANSI Z136.3 Standard is Here!

ORLANDO, FL, Jan. 23, 2012 — In response to the extensive adoption of lasers for medical procedures, the Laser Institute of America announces a significantly updated guideline for the use of such devices beyond the highly regulated hospital environment.

The revised “ANSI Z136.3 Safe Use of Lasers in Health Care” publication defines the parameters of safe laser use in clinical, hospital, dentistry and veterinary facilities. The revision released this month includes new guidelines and information on:

• Wavelengths employed in medical environments.

• The duties of laser safety officers involved with rented or borrowed laser equipment.

• Audit requirements and procedures.

• Clinically relevant terminology.

Laser-Based Production of Thin Wear Protection Films

By: Dominik Hawelka

Friction creates a loss of energy and reduces component lifetime. According to the scientific community concerned with friction, wear and wear protection the overall costs related to these issues amount to 4 % of the Gross National Product of industrial countries, a staggering sum. Despite the fact that wear protection coatings are already deployed to improve the life-time of highly stressed components, limiting costs due to tribological loss mechanisms poses a great challenge in many industrial sectors. In particular, within the automobile sector, a high throughput of parts needs to be protected every year. As a consequence there is a strong demand for low-cost production processes for wear protection coatings.

Aluminum Welding with High Brightness Diode Lasers

Why is Aluminum Welding such a Hot Topic?

New CAFE standards demanding an average fleet gas mileage of 54.5 mpg by 2025 will not only require radical engine improvements, but also drastically weight reduced cars. Using aluminum instead of steel can decrease the weight of a car body up to 50%, as shown in the Audi A8, which was 239 kg lighter than its steel predecessor when it was introduced in 1994.

Joining aluminum initially represented quite a challenge, but is now mainly solved with riveting, MIG welding, and to a large extent by laser welding, enabled by new laser technologies.
