Kusankhidwa kwa ma elekitirodi owotcherera molingana ndi kapangidwe kake, makina amakina, zofunikira zotsutsana ndi kusweka, nthawi yomweyo, poganizira kapangidwe kake, makulidwe achitsulo, zikhalidwe zogwirira ntchito, kupsinjika, magwiridwe antchito ndi zinthu zina zonse kusanthula kwathunthu.Ngati ndi kotheka, kuchita kuwotcherera mayeso, kupanga lolingana miyeso luso, ndiyeno kudziwa kusankha elekitirodi.
The mpweya zitsulo kuwotcherera elekitirodi kuti ambiri ntchito ndi mphamvu ya sukulu zitsulo, poganizira dongosolo zovuta, mbale, kuuma lalikulu, mphamvu katundu, kuwotcherera osauka, ambiri ntchito pulasitiki, mkulu zimakhudza kulimba, crack kukana ntchito zabwino otsika hydrogen elekitirodi. , mwachitsanzoE7018,E7016.Ngati pali zofunika zapadera kwa malo kuwotcherera, ntchito lolingana elekitirodi wapadera, monga elekitirodi, grounding elekitirodi of ofukula pansi kuwotcherera etc. E6011, E6010.Pofuna kukonza kuwotcherera bwino, chitsulo ufa elekitirodi angagwiritsidwe ntchito.
Kupatula kuzizira kwa weld mwachangu, kuwonjezereka kwamphamvu, ming'alu yowotcherera ndiyosavuta kupanga.Pa nthawi yomweyo, akhoza kusankha mphamvu kuposa m'munsi zitsulo otsika mlingo wa elekitirodi;otsika mpweya zitsulo ndi otsika aloyi zitsulo pakati zosiyanasiyana kuwotcherera zitsulo, zitsulo zambiri ntchito ndi milingo otsika kwambiri lolingana electrode ndi kuganizira otsika aloyi zitsulo chinthu, kusankha otsika mtundu haidrojeni ndi koyenera.
Pakuti kuwotcherera mpweya zitsulo, chifukwa zitsulo munali mkulu mpweya okhutira, kuonjezera kuwotcherera mng'alu chizolowezi, amene amagwiritsidwa ntchito otsika ma elekitirodi wa haidrojeni ndi preheating, pang'onopang'ono kuzirala njira ndi lolingana kuwotcherera ndondomeko miyeso, mukhoza kusankha.E6013, J422ndi etc..
About kuponyedwa zitsulo kuwotcherera, munali apamwamba mpweya, workpieces lolemera, dongosolo zovuta, n'zosavuta kupanga kuwotcherera mng'alu, pamene zitsulo aloyi chinthu kwa nthawi yaitali, ndi otchuka kwambiri.General kusankha otsika haidrojeni mtundu kuwotcherera elekitirodi, ndi kutenga preheating, wosakwiya kuzirala ndi njira zina ndi lolingana kuwotcherera ndondomeko ndi miyeso ina.
Kodi ndi kuonetsetsa kuwotcherera khalidwe ndi workpiece weld adzakhala woyera, palibe mafuta, dzimbiri, chinyezi, utoto ndi dothi, etc., pa ntchito otsika ma elekitirodi wa haidrojeni n'kofunika kwambiri.
(Pa otsika ma elekitirodi wa haidrojeni, kuwotcherera ma elekitirodi adzakhala ndi 350 DEG C kuphika kwa ola 1, ndi kuyanika ndi ntchito, kapena zosavuta kutulutsa porosity, slag, ming'alu ndi zolakwika zina. , ngati chinyezi, malinga ndi malangizo Buku kutentha kuwotcherera pamaso kuphika, koma kutentha kwambiri adzawononga kuwotcherera ndondomeko ntchito.
