Laser bidezko soldadura teknologia

2021-03-15
Laser bidezko soldadura teknologia fusio bidezko soldaduraren teknika da, laserra izpi bat erabiltzen duena energia iturri gisa soldadura artikulazioan eragiteko soldaduraren xedea lortzeko.
1. Laser bidezko soldaduraren ezaugarriak
Lehenik eta behin, laserra bidezko soldadurak sarrera beroa gutxienez murriztu dezake, kaltetutako zonaren barruti metalografikoa txikia da eta beroaren eroapenaren ondorioz gertatzen den deformazioa ere txikiena da. Ez da elektrodoak erabili behar, ezta elektrodoen kutsaduraren edo kaltearen inguruko kezkarik ere. Eta kontaktu bidezko soldadura prozesua ez denez, makinaren higadura eta deformazioa minimiza daitezke. Laser izpia tresna optikoak fokatzeko, lerrokatzeko eta gidatzeko erraza da. Piezatik distantzia egokira jar daiteke eta piezaren inguruko tresnen edo oztopoen artean berriro gidatu daiteke. Beste soldadura metodo batzuk ezin dira erabili aipatutako espazio mugak direla eta. . Bigarrenik, pieza espazio itxi batean jar daiteke (hutsean edo barneko gas ingurunea kontrolpean). Laser izpia eremu txikian fokatu daiteke, eta zati txiki eta estu banatuekin solda daiteke. Soldatzeko moduko material sorta handia da, eta hainbat material heterogeneo elkarren artean lotu daitezke. Gainera, abiadura handiko soldadura automatizatzea erraza da, eta era digitalean edo ordenagailu bidez ere kontrola daiteke. Hari mehea edo mehea soldatzerakoan, ez da erraza arkuko soldadura bezalako birfunditzea.
2. Abantailaklaserrasoldadura
(1) Bero sarrera kantitatea gutxitu daiteke, beroari eragindako zonaren barruti metalografikoa txikia da eta beroaren eroapenaren ondoriozko deformazioa ere txikiena da.
(2) Thesoldadura process parameters of 32mm plate thickness single passsoldadura have been qualified, which can reduce the time required for thick platesoldadura and even eliminate the use of filler metal.
(3) There is no need to use electrodes, no concerns about electrode contamination or damage. And because it is not a contactsoldadura process, the wear and deformation of the machine can be minimized.
(4) The laserra beam is easy to focus, align and guided by optical instruments, and can be placed at an appropriate distance from the workpiece and can be redirected between the implements or obstacles around the workpiece. Othersoldadura methods are subject to the above space limitations. Can‘t play.
(5) Pieza espazio itxi batean jar daiteke (hutsean edo barneko gas ingurunea kontrolpean).
(6) The laserra beam can be focused in a small area to weld small and closely spaced parts.
(7) Soldatzeko materialen gama handia da, eta hainbat material heterogeneo elkarren artean batu daitezke.
(8) It is easy to automate high-speedsoldadura, and it can also be controlled by digital or computer.
(9) Whensoldadura thin materials or thin-diameter wires, it is not as easy to melt back as arcsoldadura.
(10) It is not affected by the magnetic field (easy for arcsoldadura and electron beamsoldadura), and can accurately align the weldment.
(11) Propietate fisiko desberdinak soldatu ditzaketen bi metal (hala nola erresistentzia desberdinak)
(12) Ez da hutsik egin behar eta X izpien babesa ez da beharrezkoa.
(13) Zuloa soldatuta badago, soldaduraren zabalera 10: 1 artekoa izan daiteke.
(14) The switching device can transmit the laserra beam to a plurality of workstations.
3. Abantailak eta desabantailak
(1) The position of the weldment must be very precise and must be within the focus of the laserra beam.
(2) When the fixture is to be used with a fixture, it must be ensured that the final position of the weldment is aligned with the weld point that the laserra beam will impact.
(3) The maximum weldable thickness is limited to workpieces with a penetration thickness of more than 19 mm, and laserrasoldadura is not suitable for use on the production line.
(4) Highly reflective and highly thermally conductive materials such as aluminum, copper and alloys thereof, the weldability is changed by the laserra.
(5) When performing medium-to-high-energy laserra beamsoldadura, a plasma controller is used to drive out the ionized gas around the molten pool to ensure re-emergence of the weld bead.
(6) Energia bihurtzeko eraginkortasuna baxuegia da, normalean% 10 baino gutxiago.
(7) Soldadura-alea azkar solidotzen da eta poroak eta kezkak izan ditzake.
(8) Ekipamendua garestia da.
4. Eskaera
Lasersoldadura machine technology has been widely used in high-precision manufacturing fields such as automobiles, ships, airplanes, and high-speed rails, which has brought significant improvements to people‘s quality of life, and has led the home appliance industry into the era of precision.
Fabrikazio industria, elektronika, biologia medikoa, automobilgintza, hautsen metalurgia eta beste arlo batzuk.
5. Itxaropenak
As a combination of modern technology and traditional technology, laserrasoldadura is particularly unique compared to traditionalsoldadura technology, and its application field and application level are more extensive, which can greatly improve the efficiency and precision ofsoldadura. Its high power density and fast energy release improve the working efficiency, and its own focusing point is smaller, which undoubtedly makes the adhesion between the stitched materials better, without causing damage and deformation of the material. The emergence of laserrasoldadura technology has enabled the application of traditionalsoldadura technology, which can easily realize varioussoldadura requirements of different materials, metals and non-metals, and because of the penetration and refraction of the laserra itself, it can be based on The trajectory of the speed of light itself achieves a free focus in the 360 degree range, which is undoubtedly unimaginable under the development of traditionalsoldadura technology. In addition, because laserrasoldadura can release a large amount of heat in a short time to achieve rapidsoldadura, it is less environmentally demanding and can be carried out under normal room temperature conditions without the need for vacuum or gas protection. After decades of development, people have the highest level of understanding and awareness of laserra technology, and it has gradually expanded from the initial military field to the modern civil field, and the emergence of laserrasoldadura technology has further expanded the application range of laserra technology. Future laserrasoldadura technology can not only be used in the fields of automobile, steel, instrument manufacturing, etc., but it can also be applied in more fields such as military, medicine, etc., especially in the medical field, with its own high heat and high. The characteristics of integration, health, etc., are better applied in clinical diagnosis and treatment of neuromedicine and reproductive medicine. And its own precision advantage will also be applied in more precision instrument manufacturing, which will continue to benefit human and social development.
