TRUMPF BrightLine Weld, Roiskeiden vähentäminen laserhitsauksessa, Hitsaustekniikka 5-18
Kuituvälitteisetlaserit ovat nyt johtavaa tek-niikkaa teollisuuden laserhitsausjärjestelmissä. Laserkuitu tuo monia etuja laserhitsauksen järjestelmärakentamiseen. Silti ”roiskeiden hallinta” on odottanut teollista ratkaisua tuottavuuden kasvattamiseksi.
Yleisesti roiskeita saadaan hallittua tie-tyllä nopeusalueella hitsattaessa. Syvätun-keumalaserhitsauksessa kuten voimansiir-ron hitsauksessa, roiskeita saadaan hallittua 5-6 m/min nopeuksilla. Yli 6 m/min nope-udella roiskeista johtuva materiaalihäviö johtaa reunahaavoihin sekä mahdollisesti lisää hitsin huokoisuutta. Molemmat on-gelmat heikentävät kappaleen mekaanisen rasituksen kestokykyä. Lisäksi jos roiskeina irronneet partikkelit ovat läsnä tai irtoavat kokoonpanon aikana, voi vaihdelaatikossa syntyä käyttövaurioita.
Tässä artikkelissa esitellään viimeisiä tuloksia, jotka käsittelevät näitä ongelmia sekä havainnollistetaan merkittävästi vähen-tyneitä roiskeita hitsattaessa suurilla nope-uksilla. Aiemmin tämä on ollut aikaisemmin mahdollista vain CO2-laserhitsauksessa. Tämä uusi menetelmä perustuu TRUMPF DiskLaserin soveltamiseen uudella säteen muokkaustavalla. Menetelmästä käytetään nimitystä BrightLine Weld ja siinä laserhit-sausnopeutta voidaan kasvattaa merkittä-västi sekä energiankulutusta voidaan vähen-tää huomattavasti.
TRUMPF Brightline, Metallitekniikka 2014/4
Uusi BrighLine teknologia tekee TruLaser 5030 fiber koneesta monikäyttöisen kuitulaserleikkurin. BrightLine tegnologian avulla laserleikkausasetusten vaihto ohuesta materiaalista paksuun on erittäin nopeaa. Tämä tuo TRUMPF:n uuteen TruLaser 5030 fiber kuitulaserleikkuriin ennen näkemätöntä joustavuutta ja tuotantotehokuutta. Sen 5 kilowatin TruDisk pystyy leikkaamaan erinomaisella laadulla jopa 25mm paksuja ruostumattomia teräksiä.
Keyhole Depth is just a Distance, Laser Technik Journal 2014/04
Talking about laser welding predominately means talking about the generation of a keyhole, the physics behind and invariably the depth of this steam capillary. Having the ability to measure this depth would undoubtedly raise the confidence in laser welding and also raise the quality of the processed part on a higher level. With the IDM (In-Process Depth Meter), Precitec developed a sensor system that is able to measure the depth of the keyhole in-process. On the basis of low-coherence interferometry, with a high robustness of the measured values against process emissions, the system is perfectly qualified to provide the measurement that the industry has been asking about for decades.
Laser surface modifications in steel industry, Laser Technik Journal 2013/03
Components used in the manufacture of steel strip work in exceptionally aggressive environments and have to withstand service at high temperatures in corrosive atmospheres under mechanical wear and frequent and heavy impact loading. Conventionally, components that are subject to high wear or corrosion have often been manufactured from rich chemistry steels or hardfaced using submerged arc clad martensitic stainless steels to increase their campaign life and therefore maximise line throughput by extending maintenance intervals without any sacrifice to product quality.
