近年、生産ラインでは、より高出力な切断および溶接レーザー装置が導入されていますが、時間不足や複雑性のため、生産プロセ ス中にレーザービームの品質がチェックされていないことがあります。レーザー加工の品質には、レーザー自体の品質が直接関連 するため、自動車産業などスループットの高い生産ラインでは、大量の欠陥部品が出る可能性があります。損失や安全性の問題の リスクが大幅に高まるだけでなく、レーザービームの品質をモニターしていないと、問題が発生した時の根本的な原因を見つける ことができません。

この様な問題に対処するため、BeamWatch Integratedは開発されました。特許である非接触BeamWatchの測定原理（レイリー散 乱を使用）に基づき、この技術は、ビデオレートでビーム集光曲線に沿った複数のプロファイルの同時計測を可能にし、数分の１ 秒でISO13694およびISO11146規格に準拠したビームの主要パラメーターが計測できます。リアルタイムの測定により、NISTトレ ーサブルのパワーセンサーで値を読み取る間に、焦点シフトの検出も可能です。

シャッター付きで丈夫に設計されたBeamWatch Integratedは、コンパクトな自己完結型システムで、様々な種類の溶接ヘッドに対 応します。多様なインターフェースにより、システムを生産ネットワークや自動製造ラインに統合し、測定データを簡単に直接転送 することが可能です。

短時間計測により、積み込み／積み下ろし中に、各生産ユニットごとにレーザービームの自動チェックが可能です。さらに、標準イ ンターフェースを使用してすべてのパラメーターを読み取り、プロセスモニタリングの一部として、必要に応じて個別の構成部品ご とに一貫して文書化することが可能です。大量の測定データに基づくため、図表化された傾向は精度が高く、予知保全に役立つデ ータが得られます。

測定するパラメーターには許容値や上限値を設定することで、必要に応じて是正措置を行うトリガーが可能です。非接触測定によ り計測器の摩耗が起こらないため、BeamWatch Integratedは、ほぼメンテナンスなしで動作します。

Short measurement time for frequent measurements during shift operation
Two options for single-mode or multi-mode lasers available
 
Although ever more powerful cutting and welding laser equipment is being used on modern production lines, all too frequently – due either to lack of time or to the complexity – the quality of the laser beam goes unchecked during the production process. Because laser process quality is directly linked to laser quality, this can lead to large batches of defective parts in high-throughput production lines, e.g. in the automotive industry. In addition to the significantly higher risk of loss or safety issues, neglecting to monitor the quality of the laser beam consistently makes it almost impossible to detect the root cause of problems, when they occur.
 
To address this issue, BeamWatch Integrated was developed. Based on the patented non-contact BeamWatch measurement principle (using Rayleigh scattering), this technology provides for the simultaneous measurements of multiple profiles along the beam caustic at video rates, delivering – in mere fractions of a second – all the beam key parameters according to ISO 13694 and ISO 11146 standards. Real-time performance also allows for detection of dynamic focal shift, while a NIST-traceable power sensor assures absolute power readings. With its shutter and rugged design, BeamWatch Integrated is a compact and self-contained system that can accommodate different types of welding heads. A variety of interfaces makes it possible to integrate the system into production networks and automated manufacturing lines to facilitate direct transfer of measurement data.
 
The short measurement times allow the laser beam to be checked automatically during the loading / unloading phase, as frequently as once every produced unit. Additionally, all parameters can be read out using standard interfaces and – as part of the process monitoring – consistently documented for each individual component, as desired. Since they are based on a large amount of measurement data, trend diagrams are highly accurate and can therefore deliver useful insights for predictive maintenance.
 
Tolerances and limit values can be set up for measured parameters to trigger corrective actions as needed. BeamWatch Integrated operates virtually without maintenance, because contactless measurement exerts no wear on the instrument.

(1) For circular beam centered within ¼ of beam diameter. IMPROPERLY CENTERED BEAM CAN CAUSE DAMAGE TO SENSOR. Maximum tilt angle on power sensor ±5 degrees. For rectangular beam please consult MKS Ophir representative
(2) Water temperature rate of change <1ºC/min. The recommended flow rate can be lowered proportionately at lower than full power but should not be below 3 liter/min. The response time will be optimum with the recommended flow rate.

    The system can be manually operated by PC using BeamWatch, our full-function software with an extensive set of ISO quantitative propagation measurements, NIST calibrated power measurements, graphical representations of the beam caustic. Requires user supplied PC.
     
    The system can alternatively be operated automatically by PLC using PROFINET, EtherNet/IP or CC-Link. Tolerances and limit values can be set-up for desired measured parameters to trigger corrective actions. The trend charts give insights for early problem detection and predictive maintenance.
     
    In both cases PDF and CSV reports can be generated.
