I-Welding Technique ye-PDC

Njengoba isihloko sethu sokugcina sibonisa, ngokwendlela yokushisa, indlela yokugqamisa ingahlukaniswa ibe yi-flame brazing, i-vacuum brazing, i-vacuum diffusion bonding, i-high-frequency induction brazing, i-laser beam welding, njll. Kulesi sihloko masiqhubeke nalokhu phezulu futhi size ekushiseni kwe-high-frequency induction brazing, kanye ne-laser beam welding.

PDC high-frequency induction brazing

I-high-frequency induction brazing isebenzisa induction ye-electromagnetic ukuguqula amandla kazibuthe abe amandla okushisa ensimbi yokugcwalisa i-brazing kanye nocezu lokusebenza, kushisisa insimbi yokugcwalisa i-brazing ibe yisimo esincibilikisiwe. Inqubo ye-PDC ye-high-frequency induction brazing iwubuchwepheshe obubalulekile bokubraza amathuluzi okusika e-PDC.

Inzuzo ye-PDC ye-high-frequency induction brazing:

1.    isivinini sokushisisa siyashesha, esinganciphisa ukulahlekelwa okuvuthayo kwe-PDC polycrystalline diamond layer kanye ne-oxidation degree ye-carbide enosimende.

2.    qinisekisa ukunemba kobukhulu bezingxenye

3.    cishe akukho ukungcoliswa kwemvelo

4.    kulula ukubona ukukhiqiza okuzenzakalelayo.

I-PDC laser beam welding

I-Laser Beam Welding isebenzisa i-laser density ephezulu ye-laser njengomthombo wokushisa, ngokulawula ububanzi be-laser pulse, amandla, amandla aphezulu, imvamisa yokuphindaphinda, namanye amapharamitha ukwenza isiqeshana sokusebenzela sifinyelele ekujuleni okuthile kwechibi elincibilikisiwe, kuyilapho indawo engaphezulu inezingqimba. akukho vaporization esobala, ngakho-ke ukushisela kungenziwa.

Ubuningi bamandla we-laser beam bungafinyelela ku-10 9 W / cm 2. Ngenxa yobuningi bamandla amakhulu, izimbobo ezincane zenziwa ezintweni zensimbi ngesikhathi senqubo yokushisela.

Amandla e-laser adluliselwa engxenyeni ejulile ye-workpiece ngokusebenzisa izimbobo ezincane, kunciphisa ukuhlukaniswa kwe-lateral kanye nokujula kwe-fusion yento.

Izici ze-laser beam welding:

1.    ukujula okukhulu kwe-fusion kwento, isivinini sokushisela esisheshayo, nendawo enkulu yokushisela ngesikhathi seyunithi ngayinye

2.    i-weld seam ejulile futhi emincane, indawo encane ethinteke ukushisa, kanye nokonakala kwe-welding.

Ukusebenzisa i-laser ukushisela i-PDC, ijoyinti elishiselwe elitholiwe linamandla amakhulu, afinyelela ku-1 800 MPa, futhi ngeke lilimaze ungqimba lwedayimane. Kuyindlela ekahle ye-PDC yokushisela, esetshenziswa kakhulu ukushisela izindwani zedayimane eziyindilinga.

Ucwaningo nokukhuthazwa kwe-PDC kuthuthukise kakhulu ikhono lokusika lezingcezu zokubhola namathuluzi futhi uma kuqhathaniswa nedayimane lemvelo, linokusebenza okuhle kwezindleko. Uma kucatshangelwa izidingo zokusebenza kanye nezindleko ze-PDC, inqubo efanelekile yokushisela ingakhethwa.

Uma unentshisekelo kubasiki be-PDC futhi ufuna ulwazi olwengeziwe kanye nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE I-IMEYILI ezansi nekhasi.
