Improved results for laser cutting and welding Coherent/Rofin has introduced new products to enhance fibre laser welding and enable superior process control in both cutting and welding. heads, extensive welding knowledge and in-house applications development capabilities, to provide customers with a laser welding package that is well- matched to their process.

loss of cut and plasma formation. Welding processes can be monitored to detect defects like blow holes, missing connections and insufficient penetration. This data can then be utilised by quality management systems to increase yields, and reduce scrap and rework.

The new CleanWeld technology, which was premiered at EuroBLECH, is an integrated approach to fibre laser welding that is claimed to deliver up to 80 per cent spatter reduction, as well as minimal cracking and porosity. In addition to improved process consistency, it allows some welding processes to be performed with 40 per cent less laser power, leading to cost savings. CleanWeld integrates the company’s expertise in several areas of fibre laser welding to deliver improved results and increased yield. These include the ability to produce unique beam intensity profiles, including the new ARM (adjustable ring mode) fibre laser. This is combined with the company’s process- optimised delivery optics and focusing

Another product debut at EuroBLECH was the new HighLight SQD high-power fibre lasers, which incorporate “smart” QD fibre connectors. These lasers include lightweight, compact process sensors that are integrated directly in the SQD fibre connector. The sensors deliver information to signal important process events such as piercing end,
