Iintlobo zokunyibilika kwesinyithi kwi-Flash Butt Welding

I-flash butt welding yinkqubo ye-welding ekhethekileyo exhomekeke ekuveliseni ubushushu obunzulu ukudibanisa isinyithi kunye. Obu bushushu buveliswa ngesenzeko esibizwa ngokuba kukudanyaza, kwaye kuthatha kwiifom ezahlukeneyo ngokuxhomekeke kwiintsimbi ezidityanisiweyo kunye neemeko ezithile zokuwelda. Kweli nqaku, siza kuphonononga iindlela ezahlukeneyo zokunyibilika kwesinyithi kwi-flash butt welding kunye nokubaluleka kwazo kwishishini le-welding.

1. Ubushushu bokumelana nobushushu: Kwi-flash butt welding, enye yeendlela eziphambili zokunyibilika kwentsimbi yenzeka ngokufudumeza okuxhathisayo. Xa iintsimbi zokusebenza ezimbini zidityaniswa, umbane ophezulu ugqithiselwa kuzo. Lo wangoku uhlangabezana nokuchasana kwindawo yoqhagamshelwano, ukuvelisa ukushisa okukhulu. Ubushushu bendawo buphakamisa ubushushu bezinto zokusebenza, zibangele ukuba zinyibilike kwaye ekugqibeleni zidibanise kunye.
2. Ukudanyaza kwe-Arc: Ukudanyaza kwe-arc lolunye uhlobo lokunyibilika kwesinyithi kwi-flash butt welding, ebonwa ngokuqhelekileyo xa udityanisa izinto ezingezizo i-ferrous ezifana ne-aluminiyam. Kule nkqubo, i-arc yombane ibethelwa phakathi kwezinto zokusebenza ngaphambi kokuba zidibene. Ubushushu obukhulu obuveliswa yi-arc bubangela ukuba imiphetho yezinto zokusebenza zinyibilike, kwaye xa zinyanzeliswa ndawonye, ​​zixubana ngentsimbi etyhidiweyo.
3. I-Melting Melting: I-Melting melting yindlela ekhethekileyo yokunyibilika kwesinyithi kwi-flash butt welding eyenzeka ngexesha "lokuphazamiseka" kwesigaba senkqubo. Esi sigaba sibandakanya ukufaka uxinzelelo lwe-axial kwizixhobo zokusebenza, ukubanyanzela ukuba badibane. Njengoko i-workpieces zixinzelelwe, ubushushu obuveliswa kuxinzelelo olunamandla lubangela ukunyibilika kwendawo kwi-interface. Esi sinyithi sinyibilikisiwe ke ngoko siyaqina senze iqhina eliqinileyo, lesinyithi.
4. I-Solid-State Bonding: Kwezinye izicelo ze-flash butt welding, ukunyibilika okupheleleyo kwezinto zokusebenza akunqweneleki, njengoko kunokubangela utshintsho lwe-metallurgical kunye namalungu abuthathaka. I-Solid-state bonding yindlela yokudibanisa isinyithi apho izixhobo zokusebenza zidibene ngaphandle kokufikelela kwiindawo zazo zokunyibilika. Endaweni yoko, uxinzelelo oluphezulu lusetyenziswa ukwenza idiffusion bond phakathi kweathom kwi-interface, iqinisekisa ikhonkco eliqinileyo nelicocekileyo.

Ukuqukumbela, i-flash butt welding yinkqubo eguquguqukayo eneendlela ezahlukeneyo zokunyibilika kwesinyithi, nganye ilungele ukusetyenziswa kunye nezixhobo ezahlukeneyo. Ukuqonda ezi fomu kunye neziphumo zazo kubalulekile ekufezekiseni iiwelds ezikumgangatho ophezulu kumashishini ahlukeneyo, ukusuka kwiimoto ukuya kwi-aerospace. Nokuba kungenxa yokufudumeza okuxhathisayo, ukudanyaza kwe-arc, ukunyibilika okuphazamisekileyo, okanye ukuhlangana kwelizwe eliqinileyo, ukuguquguquka kwe-flash butt welding kudlala indima ebalulekileyo kwimveliso yangoku kunye nolwakhiwo.
