Kupisa kwemhepo kunopisa kunonziwo hot air welding. Mhepo yakamanikidzwa kana gasi inert (kazhinji nitrogen) inopisa kusvika kune inodiwa tembiricha kuburikidza nehita mupfuti yewelding uye yakapfapfaidzwa pamusoro pepurasitiki pepamusoro uye welding strip, kuitira kuti zviviri izvi zvinyunguduke uye zvibatanidzwe pasi pekumanikidza kudiki. Mapurasitiki anonzwa oksijeni (senge polyphthalamide, nezvimwewo) anofanirwa kushandisa gasi inert semudziyo wekudziya, uye mamwe mapurasitiki anogona kushandisa mweya wakasefa. Iyi nzira inowanzoshandiswa pakugadzira mapurasitiki akadai se polyvinyl chloride, polyethylene, polypropylene, polyoxymethylene, polystyrene, uye carbonate.
Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Kupisa pressure welding inoshandisa kudziyisa nekumanikidza kudzvanya waya yesimbi nenzvimbo yesimbi yewelding pamwechete. The musimboti kuita simbi iri nomoto nzvimbo plastically deform nokupisa uye kumanikidzwa, uye panguva imwe chete kuparadza oxide layer pamusoro kumanikidzwa welding interface, kuti kuonana pamusoro pakati kumanikidzwa nomoto waya uye simbi inosvika atomu rinokwevera. siyana, nokudaro zvichigadzira kukwezvana pakati peatomu uye kuzadzisa chinangwa chekubatana.
Hot plate welding inotora dhizaini-kudhirowa chimiro, uye kupisa kwemuchina wekudziya ndiro kunotamirwa kune welding pamusoro pepamusoro nepasi pepurasitiki kupisa zvikamu nekudziya kwemagetsi. Iyo yepamusoro inonyungudutswa, uye ipapo muchina wekudziya ndiro inobviswa nekukurumidza. Mushure mekunge nzvimbo dzepamusoro uye dzepasi dzekudziya dzadziyirwa, nzvimbo dzakanyungudutswa dzinosanganiswa, dzakasimba, uye dzakabatanidzwa kuita imwe. Muchina wese iforomu fomu, ine mahwendefa matatu: iyo yepamusoro template, iyo yepasi template, uye inopisa template, uye yakashongedzerwa neinopisa mold, yepamusoro uye yakaderera epurasitiki inotonhora mold, uye maitiro ekuita pneumatic control.
Ultrasonic simbi welding inoshandisa yakakwira-frequency vibration waves kuendesa kune maviri simbi nzvimbo kuti isungirwe. Nekudzvanyirirwa, masimbi maviri anokweshana kuti aite musanganiswa pakati pema molecular layer. Mabhenefiti ayo anokurumidza, ekuchengetedza simba, yakakwira fusion simba, yakanaka conductivity, hapana sparks, uye pedyo nekutonhora kugadzirisa; zvisingabatsiri ndezvokuti zvikamu zvesimbi zvakasungirirwa hazvigoni kuva zvakakora (kazhinji zvishoma kudarika kana kuenzana ne5mm), nzvimbo ye weld haigoni kuva yakakura, uye kumanikidzwa kunodiwa.
Laser welding inzira inoshanda uye chaiyo yewelding inoshandisa yakakwirira-simba-density laser beam sechinhu chekupisa. Icho chimwe chezvinhu zvakakosha zvekushandiswa kwelaser material processing technology. Kazhinji, inoenderera mberi laser beam inoshandiswa kupedzisa kubatana kwezvinhu. Yayo metallurgical physical process yakafanana neelectron beam welding, kureva kuti, simba rekushandura simba rinopedzwa kuburikidza ne "key-hole" chimiro. Iyo tembiricha yekuenzanisa mumhango inenge 2500 ° C, uye kupisa kunotamiswa kubva kunze kwemadziro ekupisa kwepamusoro-soro kunyungudutsa simbi yakakomberedza mhango. Iyo kiyi hole yakazadzwa nepamusoro-tembiricha steam inogadzirwa nekuenderera mberi evaporation yemadziro zvinhu pasi pekuvhenekesa kwedanda.
Danda rinoramba richipinda mugomba rekiyi, uye zvinhu zviri kunze kwegomba rekiyi zvinoramba zvichiyerera. Sezvo danda richifamba, gomba rekiyi rinogara rakagadzikana rekuyerera. Simbi yakanyungudutswa inozadza mukaha wasara mushure mekunge buri rekiyi rabviswa uye radzika, uye weld inogadzirwa.
Brazing inzira yewelding umo iyo yakanyungudutswa yekuzadza (brazing material) ine yakaderera kunyungudika pane iyo workpiece inofanira kubatanidzwa inodziya kune tembiricha iri pamusoro penzvimbo inonyunguduka kuti iite mvura yakakwana kuzadza nzvimbo pakati pezviviri zvebasa necapillary. chiito (chinonzi kunyorova), uyezve zviviri zvinobatanidzwa pamwe chete mushure mekunge zvaoma. Pachivanhu muUnited States, tembiricha dzinopfuura 800°F (427°C) dzinonzi brazing (hard soldering), uye tembiricha dziri pasi pe800°F (427°C) dzinonzi soft soldering (soft soldering).
Manual welding inzira yewelding inoitwa nehandheld welding torch, welding gun kana welding clamp.
Resistance welding inzira yekugadzira uye tekinoroji inoshandisa kupisa kujoina simbi kana zvimwe zvinhu zve thermoplastic zvakaita semapurasitiki. Iyo inzira yewelding nekuisa kumanikidza kuburikidza nemagetsi mushure mekunge maworkpieces aunganidzwa uye kushandisa kupisa kwekudzivirira kunoitwa neazvino ichipfuura nepakati pekubatana pamusoro pejoinhi uye yakatarisana nenzvimbo.
Friction welding ndiyo yakasimba phase welding nzira inoshandisa mechanical simba sesimba. Inoshandisa kupisa kunokonzerwa nekukakavadzana pakati pezviso zvekupedzisira zvezvishandiso zvekushanda kuti zvisvike kune imwe nyika yepurasitiki, uye ipapo kugadzira kwepamusoro kunoshandiswa kupedzisa welding.
Electroslag welding inoshandisa kupisa kwekudzivirira kunogadzirwa neazvino ichipfuura nepakati pe slag senzvimbo yekupisa kunyungudutsa simbi yekuzadza uye nehwaro zvinhu, uye mushure mekuomeswa, kubatana kwakasimba pakati peatomu esimbi kunoumbwa. Pakutanga kwekushongedza, waya welding uye welding groove ipfupi-yakatenderedzwa kuti itange arc, uye diki diki flux yakasimba inoramba ichiwedzerwa. Kupisa kwearc kunoshandiswa kuinyungudutsa kuita liquid slag. Kana iyo slag inosvika kune imwe yakadzika, kukurumidza kwekudya kwetambo yewelding inowedzera, uye magetsi anoderedzwa, kuitira kuti waya welding inopinzwa mudziva re slag, arc inodzima, uye electroslag welding process inoshandurwa. Electroslag welding inonyanya kunyunguduka nozzle electroslag welding, non-melting nozzle electroslag welding, wire electrode electroslag welding, plate electrode electroslag welding, etc. Zvayakaipira ndezvekuti kupisa kwekupinza kwakakura, mubatanidzwa unogara pakupisa kwakanyanya kwenguva yakareba, iyo weld iri nyore kupfutidza, iyo weld simbi ndeye yakakasharara crystalline cast chimiro, iko kuomarara kwakadzikira, uye weldment kazhinji inoda kuve yakajairwa uye kudzikamiswa mushure mekupinza.
High-frequency welding inoshandisa kupisa kwakasimba sesimba. Munguva yekuputika, kupisa kwekudzivirira kunokonzerwa ne-high-frequency current mu workpiece kunoshandiswa kupisa pamusoro penzvimbo yebasa rekushanda kune imwe yakanyungudutswa kana inenge yepurasitiki, uye ipapo (kana kwete) simba rinogumbura rinoshandiswa kuti riwane simbi yekubatanidza.
Kupisa kunyungudika imhando yekubatanidza iyo inogadzirwa nekudziisa zvikamu kune (mvura) yekunyungudika.
