Lesi sihloko sihlola umqondo wesibonelelo sokwenza ngaphambilini emishinini yokushisela. Imvume yokufoja ngaphambilini, eyaziwa nangokuthi ukugoba kwangaphambili noma ukushisisa kwangaphambili, kuyisinyathelo esibalulekile enqubweni yokushisela esiza ekulweni nemiphumela yokuhlanekezela ngesikhathi sokushisela. I-athikili ixoxa ngokubaluleka kwemvume yokufoja ngaphambilini, inani layo eliphezulu, kanye nomthelela wayo kwikhwalithi ye-weld nokusebenza. Abashiseli bangazuza ekuqondeni nasekusebenziseni le ndlela ukuze bathole ukushisela okunembile nokungahlanekezeli.
Isibonelelo se-pre-forging iyindlela ebucayi esetshenziswa emishinini yokushisela ukuze kuncishiswe izinselele zokuhlanekezela okubangelwa ukushisela. Kuhilela ukukhwabanisa kwe-workpiece ngaphambi kokushisela, okuholela ekulawuleni inqubo yokushisela elawulwayo nenembile.
- Ukuqonda Isibonelelo Sangaphambi Kokufoja Imvume yokuqamba kusengaphambili isho ukuwohloka okuncane noma ukugoba kocwecwe ngaphambi kokushisela. Le nqubo ihlose ukunxephezela ukucindezeleka okushisayo nokuhlanekezela okwenzeka ngesikhathi senqubo yokushisela. Ngokwenza umsebenzi owenziwe ngaphambili, ama-welders angafinyelela ukuqondanisa okungcono nokufaneleka, ukunciphisa ingozi yokuguqulwa kwe-post-weld.
- Ukunquma Isibonelelo Esifanelekile Sangaphambi Kokufoja Imvume efanelekile yokufoga iyahlukahluka kuye ngokuthi insimbi eshiselwe, idizayini ehlanganyelwe, kanye nenqubo yokushisela esetshenzisiwe. Abashiseli nonjiniyela kufanele bacabangele izici ezifana nezakhiwo ezibonakalayo, ukujiya, namapharamitha wokushisela ukuze banqume isibonelelo esifanele sokufoja ngaphambilini sohlelo oluthile. Ukuthola ibhalansi efanele kubalulekile ukuze ugweme ukugoba ngokweqile, okungaholela ezindabeni ezinjengokuncipha kwe-weld nokuhlanekezela.
- Umthelela Kukhwalithi Ye-Weld Nokusebenza Ukusebenzisa imvume efanele yokufoja ngaphambili kungathuthukisa kakhulu ikhwalithi ye-weld nokusebenza. Ngokunciphisa ukuhlanekezela, inqubo iqinisekisa ukuthi i-weld joint igcina umumo nobukhulu obuhlosiwe. Ama-welds angahlanekezelwe anikela ekuthuthukisweni kobuqotho besakhiwo, ukunemba kobukhulu, kanye nobuhle be-weld bubonke.
Izindawo Zokufaka Isicelo: Isibonelelo sokubumba kusengaphambili sivame ukusetshenziswa ezinhlelweni zokushisela ezihlukahlukene, okuhlanganisa i-butt welding, i-fillet welding, kanye ne-T-joint welding. Kuzuzisa kakhulu uma usebenza ngezinto eziwugqinsi noma ukumiswa okuhlanganyelwe okuyinkimbinkimbi, lapho ukuhlanekezela kungenzeka kakhulu.
Isibonelelo se-pre-forging iyindlela ebalulekile emishinini yokushisela esiza ukubhekana nezinselele zokuhlanekezela ngesikhathi sokushisela. Ngokuhlanganisa le ndlela enqubweni yokushisela nokunquma isibonelelo esilungile esisekelwe ezintweni ezibonakalayo kanye nokucaciswa okuhlanganyelwe, ama-welders angakwazi ukufeza ama-welds anembile futhi angenawo ukuhlanekezela. Ukusetshenziswa ngempumelelo kwesibonelelo sokufojiswa ngaphambili kunomthelela ekuthuthukisweni kwekhwalithi yokushisela, ubuqotho besakhiwo, kanye nokusebenza kokushisela kukonke. Njengomkhuba obalulekile embonini yokushisela, imali yokufaka i-pre-forging iyaqhubeka nokubamba iqhaza elibalulekile ekuqinisekiseni amajoyinti okushisela asezingeni eliphezulu futhi anokwethenjelwa.
