Tsanangudzo yeSplash Defect: Splash mukuwelda zvinoreva madonhwe esimbi akanyungudutswa anoburitswa mudziva rakanyungudutswa panguva yekuwelda. Madonhwe aya anogona kuwira pamusoro pebasa rakapoteredza, zvichikonzera kuomarara uye kusaenzana pamusoro, uye zvinogonawo kukonzera kurasikirwa kwemhando yedziva rakanyungudutswa, zvichikonzera maburi, nzvimbo dzekuputika, nezvimwe zvikanganiso pamusoro pekuwelda zvinokanganisa hunhu hwemuchina wekuwelda.
Kupwanya mu welding zvinoreva madonhwe esimbi yakanyungudutswa anoburitswa mudziva rakanyungudutswa panguva yekukwesha. Madonhwe aya anogona kuwira pamusoro pebasa rakapoteredza, zvichikonzera kushata uye kusaenzana pamusoro, uye zvinogonawo kukonzera kurasikirwa kwemhando yedziva rakanyungudutswa, zvichikonzera maburi, nzvimbo dzekuputika, nezvimwe zvikanganiso pamusoro pe weld zvinokanganisa hunhu hwe weld.
Kupatsanurwa kweSplash:
Kupfapfaidza kudiki: Madonhwe ekusimba aripo pamucheto we weld seam uye pamusoro pechinhu chacho, zvichinyanya kukanganisa chitarisiko uye hazvina kukanganisa mashandiro; Kazhinji, muganhu wekusiyanisa ndewekuti donhwe iri pasi pe20% yehupamhi hwe weld seam fusion;
Kudonha kukuru: Kune kurasikirwa kwemhando, kunoonekwa semaburi, nzvimbo dzekuputika, kuchekwa kwepasi, nezvimwewo pamusoro penzvimbo.musono wekunamira, izvo zvinogona kukonzera kushushikana uye kumanikidzwa kusina kuenzana, zvichikanganisa mashandiro emusono we weld. Chinangwa chikuru chiri pamhando idzi dzezvikanganiso.
Maitiro ekupararira kwemvura:
Kupwanya kunoratidzwa sekupinza kwesimbi yakanyungudutswa mudziva rakanyungudutswa munzira yakatwasuka yakatarisana nepamusoro pemvura inokweverwa nekuda kwekumhanya kwakanyanya. Izvi zvinogona kuonekwa zvakajeka mumufananidzo uri pazasi, apo koramu yemvura inokwira kubva pakunyungudutswa kwewelding yoora kuita madonhwe, zvichiita madonhwe.
Chiitiko chezviitiko zveSplash
Kushongedza neLaseryakakamurwa kuita thermal conductivity uye deep penetration welding.
Kupinza simbi mumhepo inopisa hakuna kana kamwechete: Kupinza simbi mumhepo inopisa kunosanganisira kutamisa kupisa kubva pamusoro pechinhu kuenda mukati, pasina kana kamwechete kamwe kanobuda panguva yekushanda. Maitiro aya haabatanidzi kupwanyika kwesimbi zvakanyanya kana kuita kwesimbi.
Kupinza mvura yakadzika ndiyo mamiriro makuru apo kupinza mvura yakadzika kunoitika: Kupinza mvura yakadzika kunosanganisira kushandisa laser kusvika zvakananga muchinhu chacho, kuchiendesa kupisa kuchigadzirwa kuburikidza nemaburi emakiyi, uye maitiro acho anowanzo shandiswa zvakanyanya, zvichiita kuti ive nzvimbo huru apo kupinza mvura kwakapararira.
Sezvakaratidzwa pamufananidzo uri pamusoro apa, vamwe vadzidzi vanoshandisa mapikicha ekumhanya kwakanyanya pamwe chete negirazi rinoonekera rinopisa zvakanyanya kuti vaone mamiriro ekufamba kwegomba rekiyi panguva yekubatanidza nelaser. Zvinogona kuwanikwa kuti laser inorova madziro epamberi egomba rekiyi, ichisundira mvura kuti iyerere pasi, ichipfuura gomba rekiyi uye ichisvika kumuswe wedziva rakanyungudutswa. Nzvimbo iyo laser inogamuchirwa mukati megomba rekiyi haina kugadziriswa, uye laser iri mumamiriro ekunyungudutswa kweFresnel mukati megomba rekiyi. Kutaura zvazviri, mamiriro ekunyungudutswa kwakawanda uye kunyungudutswa, kuchengetedza kuvapo kwemvura yakanyungudutswa yedziva. Nzvimbo yekuraswa kwelaser panguva yega yega inochinja nekona yemadziro egomba rekiyi, zvichiita kuti gomba rekiyi rive mumamiriro ekufamba anotenderera. Nzvimbo yemwaranzi yelaser inonyunguduka, inopwa, inomanikidzwa, uye inoshanduka, saka vibration yeperistaltic inofambira mberi.
Kuenzanisa kwataurwa pamusoro apa kunoshandisa girazi rinopenya rinopisa zvakanyanya, iro rinofanana nekuona dziva rakanyungudutswa. Pamusoro pezvose, mamiriro ekuyerera kwedziva rakanyungudutswa akasiyana nemamiriro chaiwo. Nokudaro, vamwe vadzidzi vakashandisa tekinoroji yekukurumidza kuomesa. Munguva yekuwelding, dziva rakanyungudutswa rinoomesa nekukurumidza kuti riwane mamiriro ekukurumidza mukati meburi rekiyi. Zvinogona kuonekwa zvakajeka kuti laser iri kurova madziro epamberi eburi rekiyi, ichigadzira nhanho. Laser inoshanda pagomba iri rematanho, ichisundira dziva rakanyungudutswa kuti riyerere pasi, ichizadza gap reburi rekiyi panguva yekufamba kwemberi kwelaser, uye nokudaro ichiwana dhayagiramu yenzira yekuyerera mukati meburi rekiyi redziva rakanyungudutswa chairo. Sezvakaratidzwa mumufananidzo wakarurama, kumanikidzwa kwesimbi kunodzoserwa kunogadzirwa nekubvisa kwesimbi yakanyungudutswa nelaser kunofambisa dziva rakanyungudutswa kuti ripfuure madziro epamberi. Buri rekiyi rinofamba richienda kumuswe wedziva rakanyungudutswa, richikwira kumusoro sechitubu kubva kumashure uye richibaya pamusoro pedziva rakanyungudutswa remuswe. Panguva imwe chete, nekuda kwekumanikidzwa kwepamusoro (tembiricha yekumanikidzwa kwepamusoro yakaderera, kukanganiswa kwakanyanya), simbi yemvura iri mudziva rakanyungudutswa nemusana inodhonzwa nekumanikidzwa kwepamusoro kuti ifambe ichienda kumucheto kwedziva rakanyungudutswa, ichiramba ichioma. Simbi yemvura inogona kusimba mune ramangwana inotenderera ichidzokera kumuswe weburi rekiyi, zvichingodaro.
Dhiyagiramu yekuongorora welding yekupinda mukati megomba relaser: A: Kutungamira kwekuwelding; B: Beam reLaser; C: Keyhole; D: Utsi hwesimbi, plasma; E: Gasi rinodzivirira; F: Rusvingo rwepamberi pegomba rekiyi (kukuya kusati kwanyunguduka); G: Kuyerera kwakatwasuka kwezvinhu zvakanyungudutswa nenzira yegomba rekiyi; H: Nzvimbo yekusimba kwedziva rinonyunguduka; I: Nzira yekudzika kwedziva rakanyungudutswa.
Pfupiso:
Maitiro ekudyidzana pakati pelaser nezvinhu: Laser inoshanda pamusoro pechinhu ichi, ichiburitsa kuburitsa kwakasimba. Chinhu chacho chinotanga chapiswa, chanyungudutswa, uye chapwa. Munguva yekubuda kwemvura kwakasimba, utsi hwesimbi hunofamba huchikwira kumusoro kuti hupe dziva rakanyungudutswa kudzvanywa kunodzika, zvichikonzera buri rekiyi. Laser inopinda muburi rekiyi uye inobuda kakawanda, zvichikonzera kuti utsi hwesimbi hurambe huchichengetedza buri rekiyi; Laser inonyanya kushanda pamadziro epamberi eburi rekiyi, uye kubuda kwemvura kunoitika pamadziro epamberi eburi rekiyi. Kudzvanywa kwekudzokera shure kunosunda simbi yemvura kubva pamadziro epamberi eburi rekiyi kuti ifambe ichitenderedza buri rekiyi ichienda kumuswe wedziva rakanyungudutswa. Mvura inofamba nekumhanya kukuru ichitenderedza buri rekiyi ichakanganisa dziva rakanyungudutswa kumusoro, ichigadzira mafungu akasimudzwa. Zvadaro, ichifambiswa nekumanikidzwa kwepamusoro, inofamba ichienda kumucheto uye inosimba mukutenderera kwakadaro. Kupwanyika kunonyanya kuitika pamucheto wekuvhura buri rekiyi, uye simbi yemvura iri pamadziro epamberi ichamhanya zvakanyanya kupfuura buri rekiyi uye ichikanganisa nzvimbo yedziva rakanyungudutswa pamadziro ekumashure.
