Mabhenefiti eLaser Welding muIndasitiri yeZvishongo

Kushongedza neLaserinopa simba guru rekupinza nekumhanya, pamwe nekuramba kwakaderera, zvichiita kuti ishandiswe zvakanyanya mukugadzira zvinhu zvemazuva ano. Muindasitiri yezvishongo, zvichienzaniswa nehunyanzvi hwechinyakare hwekupinza, kupinza nelaser kune zvakanakira zvikuru.

1. Kumhanya kwakanyanya, simba guru, kukanganiswa kwakaderera - hapana kutwasanudza kana kuchenesa mushure mekuweld kunodiwa
Chikonzero chikuruvagadziri vezvishongoKushandiswa zvakanyanya kwe laser welding ndiko kukurumidza kwayo kuchinjika uye kusakanganiswa kushoma, zvichibvisa kudiwa kwekutwasanudza uye kuchenesa mushure mekuwelda. Kunyangwe laser welding ichikurumidza kupfuura yemurazvo wekare, mushandi anowanzo bata workpiece nemaoko kana zvishandiso, achiwelda chidimbu chimwe panguva. Sezvo nzvimbo zhinji dzekushandira laser welding dzezvishongo dziri diki uye dzisingakwanise kugadzirisa mabheti makuru panguva imwe chete, nguva yekuwelda inogona kuwedzera zvishoma. Zvisinei, kuderedzwa kwebasa rekuchenesa mushure mekuwelda kunotsiva nguva yekuwelda. Laser welding inogona kuitwa pasi pemhepo isina gasi, isingasiyi mavara emoto pachigadzirwa. Naizvozvo, hapana flux inodiwa, uye hapana acid pickling inodiwa mushure mekuwelda. Kazhinji, laser welding inokonzera kushanda zvakanaka kwekugadzira.

2. Yakakodzera kupinza zvikamu zvakanyatsonaka, zvichiita kuti workpiece ive yemhando yepamusoro.
Nekuti danda relaser rinogona kunangidzirwa panzvimbo diki uye rakanyatsoiswa panzvimbo chaiyo, rakanakira kugadzirwa otomatiki kwehuwandu hwakawanda. Izvi zvinovandudza zvikuru kushanda zvakanaka kwekugadzira, zvinoderedza nzvimbo inokanganiswa nekupisa, uye zvinochengetedza tsvina yeweld isina weld, zvichiwedzera zvakanyanya kunaka kweweld uye zvinoderedza mwero wekukanganisa. Semuenzaniso, kana zvishongo zve 14K alloy zvichishandiswa 58% Au uye 2% Ag nehuremu, sirivha inonamirwa, zvichideredza kuomarara kwechinhu kubva paHV 145 kusvika pahafu. Kana chikadonhedzwa kubva pahudyu kusvika pasi, chinogona kupwanyika. Uchishandisa welding yelaser ine simba shoma, inomhanyisa, kupisa kunowedzera, saka workpiece hainyungudike, nokudaro ichichengetedza simba rayo.

3. Kunyatsogadzirwa zvakanaka, zvichibatsira kugadzira zvishongo zvitsva.
Sumo yewelding nelaserKupinda muindasitiri yezvishongo kwakachinja mafungiro ekugadzira zvishongo zvechinyakare. Nekushongedza nelaser, maitiro chaiwo ekuvaka anogona kugadzirwa. Kare, zvivakwa izvi zvakakosha zvaive zvakaoma kana zvisingaite kuburikidza nekushongedza kwechinyakare. Kushongedza nelaser kunogona kuitwa munzvimbo dzakamanikana, zvichiita kuti zvive nyore kubatanidza mhando dzakasiyana dzezvinhu zve alloy pamwe chete. Saka, ruvara kana chimiro chiri pakati pezvikamu zviviri zvinogona kuchinja kamwe kamwe pasina kusanganisa. Nzvimbo yakamanikana yekushandira yekuchenesa nelaser inokonzera kusiyana kwekunyorova, kubatana, uye saizi yetsanga munzvimbo ine kupisa zvichienzaniswa nekushongedza kwechinyakare.

4. Kugadzikana kwakanaka uye kugadzikana.
Kazhinji, hapana simbi yekuzadza kana flux inodiwa - workpiece inogona kunyungudutswa munharaunda uye kusungirirwa zvakananga.

5. Zvinorerutsa basa rekugadzirisa zvinhu.
Semuenzaniso, kugadzirisa simbi pedyo nematombo anokosha, kubvisa maburi ekukanda, uye kusonera munzvimbo dziri pedyo ne0.2 mm kune zvikamu zvakaoma, zvinonzwa kupisa zvakaita semahinji, mahooks, maclasps, uye masettings.

6. Hapana kusvibiswa kwezvakatipoteredza.
Panguva yekushongedza nelaser, hapana solder kana solvent inoshandiswa, uye hapana mishonga yekuchenesa inodiwa, saka hapana dambudziko rekurasa marara.

7. Inochengetedza simbi inokosha.
Kusonta kwechinyakare kunowanzoda ukobvu hwesimbi hunosvika 0.2 mm, nepo kusonta nelaser kunogona kuderedza izvi kusvika 0.1 mm. Izvi zvinoderedza huremu hwechishongo neinenge 35–40%, izvo zvinonyanya kukosha kune zvigadzirwa zvakagadzirwa nemagetsi. Kusonta nelaser hakungochengetedze simbi inokosha chete asiwo kunochengetedza solder, uye kune kusonta kwakasiyana-siyana, mhando dzakasiyana dzesolder hadzidiwi.

8. Hunhu
Michina yekucheka nelaser inowanzoshandiswa mukugadzira zvishongo haina simba rakawanda, ine kuchengetedzeka kwakanyanya, kupfupika, uye kufamba kuri nyore, zvichiita kuti mushandi ashande zvakanaka akagara.
Muchina wekucheka we laser unowanzo shandiswa nezvishongo unogona kusanganisa simbi dzakawanda nema alloys nekukurumidza, nenzira yakavimbika, uye nemazvo, kunyange hazvo kushanda zvakanaka kuchienderana nehunhu hwechinhu chakanangwa. Kuungana kana kugadziriswa kwe castings nguva dzose kunogona kuitwa uchitungamirirwa nemaziso ne laser pulses imwe chete kana kupfuura, kazhinji pulse imwe neimwe inogara 1–20 ms. Uchishandisa stereo microscope ine crosshairs, nzvimbo yekukwevera inogona kuiswa zvakanaka, uye workpiece inogona kugadziriswa zvakanaka mukati memunda wekuona. Nzvimbo yekushanda inowanzo kuve yemhepo; kuisa mhepo kana gasi risina chinhu munzvimbo yebasa kunotonhodza, uye gasi risina chinhu rinovandudzawo kunaka kwe weld kune alloys.

9. Kupesvedzera kweAlloy Materials paLaser Welding Effect
Zvinhu zvakasiyana-siyana zve alloy zvine mhedzisiro dzakasiyana dze laser welding. Pasi pema parameter akafanana ekudzora emuchina we laser welding uye nekupisa kumwe chete kunopfuudzwa pa pulse ye welding, mhedzisiro yekunyunguduka pa pulse inosiyana nekuda kwekusiyana kwehuwandu hwekupisa kunonyungudutswa (pane kuratidzwa) nepamusoro pe alloy material. Zvinhu zvakananga zvinopesvedzera zvinosanganisira kugona kupisa kubva patembiricha yemukamuri kusvika pakunyunguduka, nzvimbo yekunyunguduka, kupisa kwakavanzika kwe fusion, uye thermal conductivity. Zvinhu zvakasiyana zvine thermal conductivity dzakasiyana, tembiricha yekunyunguduka, uye kupisa kwakavanzika kwe crystallization. Pamwe chete, zvinhu izvi zvinokanganisa zvakanyanya simba rinodiwa kuti welding ibudirire. Kunyunguduka kwakakwana kwekupisa pamusoro kunodiwa kuti welding ibudirire.
