Inkqubo ye-welding ye-flash preheating: ngaphambi kokuba i-welding eqhubekayo imisiwe, iumatshini wokuweldaifakwe ngaphambili kwintsimbi yokuqinisa. Gqoka intsimbi kumhlathi we-butt welder. Emva kokuba umbane uvuliwe, isiphelo esivulekileyo sisetyenziselwa ukwenza ubuso bokuphela kwentsimbi yentsimbi buqhekezeke ngoxinzelelo oluncinci, kwaye emva koko yahlulwe, ukuze ihlale ihlulwe kwaye irhona, rhoqo xa ichithwa, ngenxa yokumelana i-resistor yokutshitshisa kunye nokuchasana kwangaphandle kwentsimbi yentsimbi. Indawo ye-welding ishushu, kwaye xa ivulwa, i-flash of time iveliswa. Ngokuphindaphindiweyo ngokuphindaphindiweyo ngasentla, izinga lokushisa liyancitshiswa ngokuthe ngcembe, kwaye inkqubo yokufudumala iyenzeka. Emva kokufudumala, i-flash kunye nokuphazamiseka kumisiwe, kwaye iinkqubo ezimbini zifana ne-flash welding eqhubekayo. Xa usamkela uhlobo lwe-un2-150 okanye uhlobo lwe-un17-150-1 lwe-butt welder ukumisa ukuwelda kwemivalo yentsimbi enobubanzi obukhulu, kuyacetyiswa ukuba wamkele indlela yokusika okanye yokusika igesi ukumisa isiphelo sesiphelo sonyango lobuso bentsimbi yentsimbi. ; emva koko wamkele inkqubo yokushisa i-flash welding, i-hydraulic flash pair I-welder iya kuhambelana nezi mfuno zilandelayo: inkqubo yokukhanyisa iya kuba yinkimbinkimbi kwaye izinzile; iingxondorha eziphetsheya ziya kuphakanyiswa; ukulungiswa okuchanekileyo kuya kwenziwa kwaye indawo yokuqala kunye nendawo yokumisa inkqubo nganye iya kulawulwa ngokungqongqo.

Ukusetyenziswa kwesixhobo sokuwelda ngeempundu kufanele: (1) Isixhobo sokuwelda ngeempundu sifanele sifakwe ngaphakathi okanye kwishedi yokusebenzela engangenwa yimvula, yaye sifanele sibe nomhlaba oqinileyo okanye u-zero. Xa ii-welders ezininzi ze-butt zilungelelaniswa ngecala, umgama phakathi kwabo akufanele ube ngaphantsi kwe-3m, kwaye kufuneka uhlukaniswe kwigridi enesigaba esahlukileyo, kwaye i-breaker circuit kufuneka ihlulwe. (2) Ngaphambi kwe-welding, kufuneka ihlaziywe kwaye iqinisekiswe: inkqubo yoxinzelelo lwe-welder kufuneka ibe yi-dexterous, i-clamp kufuneka izinzile, kwaye uxinzelelo lomoya kunye nenkqubo ye-hydraulic kufuneka ingavuzi. (3) Ngaphambi kwe-welding, i-voltage yesibini iya kulungelelaniswa ngokwecandelo lentsimbi yentsimbi edibeneyo, kunye nentsimbi yentsimbi ngaphaya kobubanzi be-butt welder ayiyi kuxutywa. (4) I-snoring point kunye ne-electrode ye-breaker yesiphaluka iya kuhlanjululwa ngexesha, kwaye i-bolt yokudibanisa isekethe yesibini iya kuqiniswa njengoko kucwangcisiwe. Ukushisa kwamanzi okupholisa akufanele kudlule i-40 °, kwaye ukufuduka kufuneka kulungiswe ngokweqondo lokushisa. (5) Xa udibanisa imivalo yentsimbi emide, kufuneka kubekho izibiyeli. (6) Indawo edanyazayo iya kubonelelwa ngebhaffle, kwaye abasebenzi abanxulumene nokuwelda abayi kungena. (7) Xa iwelding ebusika, iqondo lobushushu akufanele libe ngaphantsi kwe-8 °. Emva komsebenzi wasekhaya, amanzi okupholisa kumatshini kufuneka aphelelwe.
