Indlela yokushisela insimbi engashisi Inqubo yokushisela isikhona ukuze ikutshele
Insimbi ekwazi ukumelana nokushisa isho insimbi enokuqina okushisayo namandla okushisa ngaphansi kwezimo zokushisa eziphezulu. Ukuzinza kwe-thermal kubhekisela emandleni ensimbi ukugcina ukuzinza kwamakhemikhali (ukumelana nokugqwala, okungenayo i-oxidation) ngaphansi kwezimo zokushisa eziphezulu. Amandla okushisa r...Funda kabanzi -
Izimbangela kanye nezinyathelo zokuvimbela ama-pores welding ku-J507 electrode
I-Porosity imbobo eyakheka lapho amabhamuza echibini elincibilikisiwe ehluleka ukuphuma phakathi nokuqiniswa ngesikhathi sokushisela. Lapho ushisela nge-alkaline electrode ye-J507, kunezimbotshana eziningi ze-nitrogen, izimbotshana ze-hydrogen kanye nama-CO pores. Isikhundla se-welding flat sinezimbotshana eziningi kunezinye izikhundla; bangu...Funda kabanzi -
Umehluko phakathi kwamajoyinti okushisela angaguquki, amajoyinti e-welding ajikelezayo kanye namajoyinti e-welding akhiwe ngaphambilini ekushiseleleni amapayipi
Kungakhathaliseki ukuthi i-welding joint ikuphi, empeleni kuwukuqoqwa kokuhlangenwe nakho kwe-welding. Kwabaqalayo, izikhundla ezilula ziyizivivinyo eziyisisekelo, eziqala ngokuzungezisayo bese zidlulela ekuzilolongeni okugxilile. Uzakwabo wokushisela okungaguquki ekushiseleni amapayipi i-weld ejikelezayo...Funda kabanzi -
Incazelo enemininingwane yenqubo yokushisela indawo
01.Incazelo emfushane I-Spot welding iyindlela yokumelana ne-welding lapho izingxenye zokushisela zihlanganiswa zibe ama-lap joints futhi zicindezelwe phakathi kwama-electrode amabili, kusetshenziswa ukushisa okumelana nokuncibilikisa isisekelo sensimbi ukuze kwakheke amalunga e-solder. I-Spot welding isetshenziswa kakhulu kulezi zici ezilandelayo: 1. Ukunqwabelana kwe-pl...Funda kabanzi -
Ngemva kokusebenza iminyaka eminingi kangaka, ngingahle ngingakwazi ukuchaza ngempela umehluko phakathi kwe-CO2, i-MIGMAG ne-pulsed MIGMAG!
Umqondo nokuhlukaniswa kwe-gas metal arc welding Indlela yokushisela i-arc esebenzisa i-electrode encibilikisiwe, igesi yangaphandle njenge-arc medium, futhi ivikela amaconsi ensimbi, i-welding pool kanye nezinsimbi ezinokushisa okuphezulu endaweni yokushisela ibizwa ngokuthi i-molten electrode gas shielded arc. ukushisela. Ngokusho...Funda kabanzi -
Yiziphi izindlela zokuhlola okungabhubhisi kwama-welds, Uyini umehluko
Ukuhlola okungabhubhisi ukusetshenziswa kwezakhiwo ze-acoustic, optical, kazibuthe nezikagesi, ngaphandle kokulimaza noma ukuphazamisa ukusetshenziswa kwento engaphansi kwesisekelo sokusebenza kwento ezohlolwa, ukuze kutholwe ubukhona bokukhubazeka noma ukungatholakali kwe-homogeneity entweni. ziyohlolwa,...Funda kabanzi -
Lesi sihloko sithatha ukuthi uqonde kalula ukukhubazeka kwe-welding - imifantu ye-lamellar
