Phakathi nenqubo yokushisela, insimbi ezoshiselwa iyashisisa, iyancibilika (noma ifinyelele esimweni se-thermoplastic) kanye nokuqiniswa okulandelayo nokupholisa okuqhubekayo ngenxa yokufaka ukushisa nokudlulisa, okubizwa ngokuthi inqubo yokushisa yokushisela.
Inqubo yokushisa yokushisela ihamba kuyo yonke inqubo yokushisela, futhi iba ngenye yezinto eziyinhloko ezithinta futhi ezinquma ikhwalithi yokushisela kanye nokukhiqiza kokushisela ngokusebenzisa lezi zici ezilandelayo:
1) Ubukhulu nokusabalalisa ukushisa okusetshenziselwa insimbi yokushisela kunquma ukuma nobukhulu bechibi elincibilikisiwe.
2) Izinga lokusabela kwe-metallurgical echibini lokushisela lihlobene eduze nomthelela wokushisa kanye nobude besikhathi lapho ichibi likhona.
3) Ukuguqulwa kwamapharamitha wokushisisa nokupholisa kwe-welding kuthinta ukuqina kanye nenqubo yokuguqulwa kwesigaba sensimbi encibilikisiwe ye-pool, futhi kuthinta ukuguqulwa kwe-microstructure yensimbi endaweni ethinteke ukushisa, ngakho-ke ukwakheka kanye nezakhiwo ze-weld kanye ne-welding ukushisa okuthintekayo. indawo nazo zihlobene nomsebenzi wokushisa ohlobene.
I-4) Njengoba ingxenye ngayinye ye-welding ingaphansi kokushisa nokupholisa okungalingani, okuholela esimweni sokucindezeleka esingalingani, okuholela emazingeni ahlukene okuguqulwa kokucindezeleka nokucindezeleka.
5) Ngaphansi kwesenzo sokushisa kwe-welding, ngenxa yethonya elihlangene le-metallurgy, izici zokucindezeleka kanye nesakhiwo sensimbi okufanele sishiselwe, izinhlobo ezihlukahlukene zokuqhekeka nezinye iziphambeko ze-metallurgical zingenzeka.
I-6) Ukushisa okokufaka kwe-welding kanye nokusebenza kahle kwayo kunquma isivinini sokuncibilika kwesisekelo sensimbi kanye nenduku yokushisela (i-welding wire), ngaleyo ndlela kuthinte ukukhiqiza kwe-welding.
Inqubo yokushisa yokushisela iyinkimbinkimbi kakhulu kunaleyo ngaphansi kwezimo ezijwayelekile zokwelashwa kokushisa, futhi inezici ezine eziyinhloko ezilandelayo:
a. Ukugxila kwendawo yenqubo yokushisa kwe-welding
I-weldment ayishisi ngokuphelele ngesikhathi sokushisela, kodwa umthombo wokushisa ushisa kuphela indawo eseduze nendawo yesenzo esiqondile, futhi ukushisa nokupholisa akulingani ngokwedlulele.
b. Ukuhamba komthombo wokushisa we-welding
Phakathi nenqubo yokushisela, umthombo wokushisa uhamba ngokuhlobene nokushisela, futhi indawo eshisayo ye-weldment ishintsha njalo. Lapho umthombo wokushisa we-welding useduze nephuzu elithile lokushisela, izinga lokushisa lephoyinti likhuphuka ngokushesha, futhi lapho umthombo wokushisa uhamba kancane kancane, iphuzu liyaphola futhi.
c. Ukudlula kwenqubo yokushisa kwe-welding
Ngaphansi kwesenzo somthombo wokushisa ogxile kakhulu, isivinini sokushisa sishesha kakhulu (esimweni se-arc welding, singafinyelela ngaphezu kuka-1500 ° C / s), okungukuthi, inani elikhulu lamandla okushisa lidluliselwa ekushiseni. umthombo we-weldment ngesikhathi esifushane kakhulu, futhi ngenxa yokushisa Izinga lokupholisa liphezulu futhi ngenxa yendawo kanye nokunyakaza komthombo wokushisa.
d. Inhlanganisela yenqubo yokudlulisa ukushisa kwe-weldment
Insimbi ewuketshezi ku-weld pool isesimweni sokunyakaza okukhulu. Ngaphakathi kwechibi elincibilikisiwe, inqubo yokudlulisa ukushisa ibuswa yi-convection yoketshezi, kuyilapho ngaphandle kwechibi elincibilikisiwe, ukudluliswa kokushisa okuqinile kuyabusa, futhi kukhona ukudluliswa kokushisa okuguquguqukayo nokudluliswa kokushisa kwemisebe. Ngakho-ke, inqubo yokushisa kwe-welding ihilela izindlela ezihlukahlukene zokudlulisa ukushisa, okuyinkinga yokudlulisa ukushisa okuhlanganisiwe.
Izici zezici ezingenhla zenza inkinga yokudlulisa ukushisa kwe-welding ibe nzima kakhulu. Kodwa-ke, ngenxa yokuthi inomthelela obalulekile ekulawuleni ikhwalithi yokushisela kanye nokwenza ngcono ukukhiqiza, i-XINFA iphakamisa ukuthi izisebenzi zokushisela kufanele zibe yinkosi yemithetho yazo eyisisekelo kanye nokushintsha amathrendi ngaphansi kwemingcele yezinqubo ezihlukahlukene.
