Abstract
The single-mode fiber laser manufactured by Furukawa Electric Co., Ltd. (FEC), with the small core diameter and the high beam quality, is capable of performing a high aspect ratio processing with little thermal influence, at low power by utilizing a high power density. Also the multi-mode fiber laser can rea遊雅堂 おすすめ over 10 mm of penetration depth for steel materials by utilizing its high output power.
However, the commonly used fiber lasers generate many sputters which cause welding defects and defacements around the processing part. To address these issues, we proceeded with the development of the beam mode 遊雅堂 おすすめrol technology and succeeded in suppressing sputters and in reducing the processing defects.
