Iingenelo zeLaser Welding kwiShishini leJewelry

Ukuwelda nge-laserInika amandla aphezulu okuwelda kunye nesantya, kunye nesantya esiphantsi sokungamkeleki, nto leyo eyenza ukuba isetyenziswe kakhulu kwimveliso yanamhlanje. Kwishishini lobucwebe, xa kuthelekiswa neendlela zemveli zokuwelda, ukuwelda nge-laser kuneenzuzo ezibalulekileyo.

1. Isantya esiphezulu, amandla aphezulu, ukugqwetheka okuphantsi - akukho mfuneko yokulungisa okanye ukucoca emva kokuwelda
Isizathu esiphambiliabavelisi bezacholoUkuwelda nge-laser kusetyenziswa kakhulu kuba isantya sayo sokuwelda sikhawuleza kwaye asiguquki kangako, nto leyo esusa isidingo sokulungisa nokucoca emva kokuwelda. Nangona ukuwelda nge-laser kukhawuleza kune-flame welding yendabuko, umqhubi uhlala ebamba umsebenzi ngezandla okanye izixhobo, ewelda into enye ngexesha. Ekubeni uninzi lweendawo zokusebenza zokuwelda nge-laser zezinto zobucwebe zincinci kwaye azinakusebenza iibhetshi ezinkulu ngaxeshanye, ixesha lokuwelda linokunyuka kancinci. Nangona kunjalo, ukuncipha komsebenzi wokucoca emva kokuwelda kuhlawula ixesha lokuwelda. Ukuwelda nge-laser kunokwenziwa phantsi kwemoya yegesi engatshiyo, kungashiyi mabala omlilo kwimveliso. Ke ngoko, akukho flux ifunekayo, kwaye akukho acid pickling ifunekayo emva kokuwelda. Lilonke, ukuwelda nge-laser kubangela ukusebenza kakuhle kwemveliso.

2. Ifanelekile kwiinxalenye zokuwelda ngokuchanekileyo, ukuqinisekisa umgangatho womsebenzi.
Ngenxa yokuba umqadi welaser ungajoliswa kwindawo encinci kakhulu kwaye ubekwe ngokuchanekileyo, ulungele imveliso ezenzekelayo enomthamo ophezulu. Oku kuphucula kakhulu ukusebenza kakuhle kwemveliso, kunciphisa indawo echaphazeleka bubushushu, kwaye kugcina ungcoliseko lwe-weld lungenazo, kuphucula kakhulu umgangatho we-weld kwaye kunciphisa amazinga eziphene. Umzekelo, xa kudityaniswa ilangabi ubucwebe be-14K alloy obune-58% Au kunye ne-2% Ag ngobunzima, isilivere iyaxutywa, kunciphisa ubunzima bento ukusuka malunga ne-HV 145 ukuya phantse kwisiqingatha. Ukuba iwiswe ukusuka esinqeni ukuya kumgangatho, isenokuqhekeka. Ukusebenzisa i-laser welding enamandla aphantsi, ekhawulezayo, ubushushu buyaxinaniswa, ukuze umsebenzi ungaxutywa, ngaloo ndlela ugcine amandla awo.

3. Ukuchaneka okuphezulu kokuhlanganiswa, okunceda ekuphuhliseni iinkqubo ezintsha zokuvelisa ubucwebe.
Intshayelelo kaukuwelda nge-laserUkutshintshela kushishino lobucwebe kutshintshe indlela yokucinga yoyilo lobucwebe bendabuko. Ngokusebenzisa i-laser welding, iindlela ezikhethekileyo zokwakha zinokwenziwa. Ngaphambili, ezi zakhiwo zikhethekileyo zazinzima okanye zingenakwenzeka ukuzifeza nge-welding yendabuko. Ukusebenzisa i-laser welding kungenziwa kwiindawo ezimxinwa kakhulu, okwenza kube lula ukudibanisa iintlobo ezahlukeneyo zezinto ze-alloy kunye. Ngoko ke, umbala okanye isakhiwo phakathi kwezinto ezimbini sinokutshintsha ngequbuliso ngaphandle kokuxuba. Indawo yokusebenza encinci yokusebenzisa i-laser welding ibangela umahluko ekumanzini, ukuthembeka kwamalungu, kunye nobukhulu bengqolowa kwindawo echaphazelekileyo bubushushu xa kuthelekiswa nokusebenzisa i-welding yendabuko.

4. Ukuqina nokuqina okuhle.
Ngokwesiqhelo, akufuneki sinyithi okanye i-flux yokuzalisa – umsebenzi unokunyibilikiswa kwindawo ethile kwaye udityaniswe ngokuthe ngqo.

5. Yenza lula umsebenzi wokulungisa izinto.
Umzekelo, ukulungisa isinyithi kufutshane namatye anqabileyo, ukususa imingxunya yokuphosa, kunye nokuwelda kwiindawo ezikufutshane ne-0.2 mm kwiindawo ezintsonkothileyo nezinobushushu ezifana neehinges, iihook, iikliphu, kunye nokuseta.

6. Akukho kungcoliswa kwendalo.
Ngexesha lokuwelda nge-laser, akukho solder okanye solvent isetyenziswayo, kwaye akufuneki neekhemikhali zokucoca, ngoko ke akukho ngxaki yokulahla inkunkuma.

7. Igcina izinto zesinyithi ezixabisekileyo.
Ukuwelda kwendabuko kudla ngokufuna ubukhulu bentsimbi obumalunga ne-0.2 mm, ngelixa ukuwelda nge-laser kunokukunciphisa oku ukuya kwi-0.1 mm. Oku kunciphisa ubunzima besiqwenga sezinto zobucwebe malunga ne-35–40%, nto leyo ebaluleke kakhulu kwiimveliso ezenziwe ngombane. Ukuwelda nge-laser akugcini nje ngokusindisa izinto zesinyithi ezixabisekileyo kodwa kukwasindisa ne-solder, kwaye kwii-weld ezininzi, iintlobo ezahlukeneyo ze-solder azifuneki.

8. Iimpawu
Oomatshini bokuwelda nge-laser abasetyenziswa kakhulu ekwenzeni ubucwebe banamandla amancinci, banokhuseleko oluphezulu, buthambile, kwaye kulula ukuhambahamba, nto leyo evumela umqhubi ukuba asebenze kamnandi xa ehleli.
Umatshini wokuwelda welaser oqhelekileyo unokuwelda ngokukhawuleza, ngokuthembekileyo, nangokuchanekileyo uninzi lweentsimbi kunye nee-alloys, nangona ukusebenza kakuhle kuxhomekeke kakhulu kwiimpawu zezinto ekujoliswe kuzo. Ukuhlanganiswa okuqhubekayo okanye ukulungiswa kwee-castings kungenziwa phantsi kolawulo olubonakalayo nge-laser pulses enye okanye ezingaphezulu, ngokuqhelekileyo i-pulse nganye ihlala i-1-20 ms. Ukusebenzisa i-stereo microscope ene-crosshairs, indawo yokuwelda inokubekwa ngokuchanekileyo, kwaye umsebenzi ungalungiswa kakuhle ngaphakathi kwendawo yokubona. Indawo yokusebenza idla ngokuba nomoya; ukungenisa umoya okanye igesi engasebenziyo kwindawo yokusebenza kubonelela ngokupholisa, kwaye igesi engasebenziyo ikwaphucula umgangatho we-weld kwii-alloys.

9. Impembelelo yezinto ze-Alloy kwi-Laser Welding Effect
Izinto ezahlukeneyo ze-alloy zineziphumo ezahlukeneyo ze-laser welding. Phantsi kweeparamitha zolawulo ezifanayo zomatshini we-laser welding kunye nobushushu obufanayo obudluliselwayo nge-welding pulse nganye, isiphumo sokunyibilika nge-pulse nganye siyahluka ngenxa yokwahluka kwinani lobushushu obufunxwayo (endaweni yokubonakaliswa) ngumphezulu wezinto ze-alloy. Izinto ezithile ezinefuthe ziquka amandla obushushu ukusuka kubushushu begumbi ukuya kwinqanaba lokunyibilika, inqanaba lokunyibilika, ubushushu obufihlakeleyo bokudibana, kunye nokuqhuba kobushushu. Izinto ezahlukeneyo zine-thermal conductivity eyahlukileyo, amaqondo obushushu okunyibilika, kunye nobushushu obufihlakeleyo bokukristala. Zidibene, ezi zinto zichaphazela kakhulu amandla afunekayo ukuze kufakwe i-welding ngempumelelo. Ukufunxwa kobushushu okwaneleyo kumphezulu kuyimfuneko ukuze kufakwe i-welding ngempumelelo.
