Abstract
W artykule przedstawiono podstawy mikrospawania laserowego. Jest to bardzo precyzyjna technika łączenia materiałów znajdująca bardzo szerokie zastosowanie w przemyśle. Wytwarzanie mikro i mezo elementów należy dzisiaj do jednego z wiodących nurtów wytwarzania, dlatego też mikrospawanie laserowe znajduje coraz większe zastosowanie i stanowi obszar intensywnych badań. W procesie tym powstaje spoina która swymi wymiarami nie przekracza 1mm. Ze względu na specyfikę oddziaływania laserowego strefa wpływu ciepła jest niewielka w stosunku do innych technik spawania. Do mikrospawania laserowego używa się laserów impulsowych Nd:YAG, CO2 lub laserów światłowodowych. Mikrospawanie jest procesem powtarzalnym, dającym efektywne spoiny i poddającym się automatyzacji.
Laser microwelding
Abstract
The paper presents some aspects of laser micro-welding. It is a very precise technique of joining materials which finds very wide application in the industry. The production of micro and meso elements is today one of the leading trends of manufacturing, so laser micro-welding is widely used in industry and is an area of intensive research. Dimensions of the welds formed in this process do not exceed 1 mm. Due to the specificity of the laser beam the heat affected zone is small in relation to other welding techniques. For laser micro-welding pulsed laser Nd:YAG, CO2 or fiber laser are used. Laser micro-welding is a repetitive process which gives an effective weld and which gives to automate.
