Kwintsimi ye-welding, ukufezekisa ibhalansi efanelekileyo yeeparamitha ze-welding kubalulekile ukuqinisekisa uxhulumaniso oluqinileyo noluthembekileyo.Enye iparameter ebalulekileyo kwi-flash butt welding yi-welding current.Xa i-welding current iphantsi kakhulu, inokukhokelela kuluhlu lweengxaki kwaye idibanise umgangatho we-weld.Kweli nqaku, siza kuphonononga imiba eyahlukeneyo enokuthi ivele xa ikhoyo ngoku ingonelanga kwi-flash butt welding.
- I-Fusion engaphelelanga: Ukungoneli kwe-welding okwangoku kunokubangela ukudityaniswa okungaphelelanga phakathi kweziqwenga ezimbini zetsimbi ezidityanisiweyo.Oku kuthetha ukuba iintsimbi zisenokunganyibiliki ngokupheleleyo kwaye zihlangane, nto leyo ekhokelela kwiiweld ezibuthathaka nezingathembekanga.Ukudityaniswa okungaphelelanga ngumba oqhelekileyo xa umsinga uphantsi kakhulu, njengoko ubushushu obuveliswayo bunganelanga ukudala idama elinyibilikisiweyo elifanelekileyo.
- Ukungena kakubi: Ukungena ngokufanelekileyo kubalulekile ukuqinisekisa ukomelela kunye nokunyaniseka kwe-weld.Xa i-welding current ingonelanga, i-weld inokungabikho ubunzulu obuyimfuneko, okubangela ukungena okungahambi kakuhle.Oku kunokunciphisa umdibaniso, okwenza kube lula ukungaphumeleli phantsi koxinzelelo okanye uxinzelelo.
- I-Porosity: I-low welding current inokubangela ukubunjwa kweepokotho zegesi ngaphakathi kwe-weld, ekhokelela kwi-porosity.Ezi pokotho zegesi zinokuthi ziphazamise ukunyaniseka kwesakhiwo somdibaniso kwaye zenze kube lula ukubola.Ubukho be-porosity kwi-weld buhlala bubonisa umgangatho ophantsi we-welding.
- IiPropati zoomatshini ezibuthathaka: Umbane we-welding owaneleyo uyimfuneko ukuze ufumane iipropati ezifunwayo zoomatshini kwi-weld, njengamandla okuqina kunye ne-ductility.Xa i-current iphantsi kakhulu, i-weld ebangelwayo ingabonakalisa amandla ancitshisiweyo kunye nokuqina, okwenza ukuba ingafaneleki kwizicelo apho kufuneka ukusebenza komatshini ophezulu.
- Ukonyuka koMngcipheko wokuNqatywa: Ukungonelanga okwangoku kunokunyusa umngcipheko wokuqhekeka kwi-weld kunye nommandla ochaphazelekayo wokushisa.Iicracks ziyakwazi ukusasaza nge-weld kwaye zidibanise ingqibelelo yesakhiwo salo lonke icandelo.Lo ngumba onzima onokuthi ukhokhelele ekungaphumeleli kwemveliso kunye neenkxalabo zokhuseleko.
- I-Welds engathembekiyo: Ekugqibeleni, xa i-welding current iphantsi kakhulu, inokubangela ukuba i-welds engathembekiyo ingakwazi ukuhlangabezana nemigangatho yoshishino okanye iimfuno.Ezi welds ze-subpar zinokukhokelela ekusebenzeni kwakhona okunexabiso elikhulu, ukulungiswa, okanye ukuchithwa kwezinto ezidityanisiweyo.
Ukuqukumbela, i-welding current iyipharamitha ebaluleke kakhulu kwi-flash butt welding, kwaye ukusilela kwayo kunokukhokelela kuluhlu lweengxaki.Ukuqinisekisa i-welds esemgangathweni ophezulu kunye nokudibanisa okunamandla, okuthembekileyo, kubalulekile ukuseta i-welding current kwinqanaba elifanelekileyo, ngokuqwalasela izinto eziphathekayo, ubukhulu kunye nezinye izinto ezibandakanyekayo kwinkqubo ye-welding.Uqeqesho olwaneleyo kunye nokubeka iliso kubalulekile ukuthintela imiba exoxwe ngasentla kunye nokugcina imfezeko yamacandelo adityanisiweyo.
