2 Modue target The aim of the modue is to famiiarise students with: basic technoogica appications of arge- and midde-power asers; physica fundamentas of operation and structure of CO and Nd:YAG asers appied in technoogy. Basic properties of aser radiation and foca radiation with materias (with metas in particuar). Students wi become famiiarised (both theoreticay and practicay) with the foowing advanced aser technoogies: meta cutting, weding, surface machining a contactess aser bending and shaping aser eements. OHS principes concerning operation with aser devices wi be presented as we. Effect symbo Teaching resuts Teaching methods (/c//p/other) Reference to subject effects Reference to effects of a fied of study U_0 U_05 K_0 A student is famiiar with basic notions concerning aser technoogy and the effects of operation as regards a aser beam on metas and non-metas; a student aso knows characteristic features of aser radiation. A student is famiiar with the principes of operation of a aser as a quantum device. A student knows OHS principes connected with aser devices and is capabe of giving first aid in the event of aser beam burns. A student can cut boards and meta sheets made from various metas; a student is aso abe to seect the parameters of a aser beam and program cutting processes. A student can wed various metas, seect weding parameters and program weding processes. A student can aser-harden carbon stee with the use of a segment mirror (with and without recasting). A student can bend meta sheets with the use of three mechanisms of contactess bending with the moving aser beam. A student can measure stee surface microhardness after aser hardening. A student can determine quaity coefficient of a CO aser beam with the use of the so-caed aser beam anayser. A student is capabe of teamwork. A student is aware of the impact of modern aser technoogies in their appication to buid machines and deveop materias engineering.

The effect of aser radiation on skin tissue and an eye depending on aser type, aser waveengths, OHS principes concerning aser devices. The impact of foca aser beam with meta surface depending on power density in a focus: heating, surface recasting and creating a channe phenomenon under meta surface. Conductive, surface, channe, and deep weding. The methods of aser meta cutting, the resuts of meta cutting depending on aser beam parameters, cutting rate, the types of appied working gases, and their fow rates. Programming cutting processes and the cut out detai shapes. Laser surface processing of metas: therma surface hardening, texturising and honing surfaces in order to modify surface ayer (e.g. improving triboogica properties). Contactess aser bending and shaping boards and meta sheets with the moving aser beam. Creating permanent and transient therma deformations. Expaining the mechanisms of aser permanent bending and sweing boards. Teaching contents as regards aboratory casses Laboratory cass number Teaching contents Practica OHS principes with aser devices and famiiarising students with the aboratory reguations during aboratory casses. The methods of programming cutting processes and the cut out detai shapes. A student s participation whie performing the assigned cutting programs. Laboratory casses on aser conductive and channe weding together with seecting the parameters of aser processing. Measuring the coefficient of beam quaity for a given weding head. Laboratory casses on cutting out meta sheets from ow-carbon stee, stainess stee and ceramics with the use of an inert gas (nitrogen and argon) or an active gas, e.g. oxygen or air. Laboratory casses on aser sampe hardening from carbon stee with the use of moving beam (with rectanguar section and with homogeneous distribution of beam density). Taking measurements of the obtained hardness with the Wickers method and making hardness sampe reationship between aser power and the rate of scanning surface. Conducting tests of effects concerning aser bending of meta sheets with the moving beam (with the use of the temperature gradient mechanism for thick-waed sampes and with the use of therma bucking depending on aser power for thin-waed sampes and ange measurements of the bending moment depending on aser power). 1 Obtaining a credit for the reports, a fina test.
