Mubasa rekugadzira nekuvaka simbi, kunyanya mubasa remapaipi nesimbi, kusarudzwa kwezvinhu zvinodiwa kwakakosha kuti pave nekuwirirana.Kukwevera maerekitirodhichinhu chakakosha mukushongedza simbi yakachengetedzwa (SMAW), ine mhando dzakagadzirirwa kushandiswa kwakasiyana. Chinyorwa chino chinopa tsananguro yehunyanzvi yeAWS E6010 classification, iyo electrode inoshandiswa zvakanyanya pakushongedza simbi yekabhoni, ichitarisa hunhu hwayo uye mashandisirwo ayo makuru.
Electrode iri kukurukurwa, inonzi J425G mune mamwe maitiro uye inoenderana neAWS E6010 uye GB/T E4310 classifications, imhando chaiyo yeWelding Electrode. Ine high-cellulose sodium coating. Iyi coating coating coating ndiyo yakakosha pakushanda kwayo, ichigadzira arc ine simba, yekuchera uye shongwe ine gasi yakawanda inodzivirira dziva re weld rakanyungudutswa, kunyanya munzvimbo dzakaoma.
Chinhu chinotsanangura izviKukwevera maerekitirodhikukodzera kwayo nzira yekubatanidza vertical-down. Yakagadzirirwa kushandiswa neDirect Current Electrode Positive (DCEP) polarity. Musanganiswa uyu unogonesa vanosanganisa simbi kuti vagadzire simbi dzesimbi dzecircumferential welds (pipe circumferential welds) nekumhanya kwakanyanya. Hunhu hwekupinda kwakadzika kweE6010 hwakakosha kuti pave nekubatana kwakakwana mumidzi.
Nheyo yekushanda kweWelding Electrode iyi inobatsira mugumisiro chaiwo uye unokosha mukukwevera mapaipi: kugona kuita weld yemidzi ine divi rimwe chete iyo inoguma nekupinza ruzha uye kuumbwa kweruzha kurutivi rwekumashure (mukati) kwepaipi, nzira inozivikanwa se "open root". Izvi zvinobvisa kudiwa kwekukwevera musana pamashandisirwo akawanda, zvichivandudza zvakanyanya kushanda kwekuvaka kwemapaipi akasiyana-siyana esimbi yekabhoni uye majoini ekuvaka.
Kurongwa kweE6010 kunomiririra chishandiso chakakosha uye chakakosha mukati mechikamu chakakura cheKukwevera maerekitirodhizvigadzirwa. Kuvhara kwayo kwe-high-cellulose, kupinza kwakadzika, uye kugona kwayo kudzika pasi kunoita kuti ive sarudzo inosarudzwa yekubatanidza midzi nemidziyo inopisa mupipeline uye kugadzira carbon steel. Kunzwisisa hunyanzvi hwekugadzira uye kushandiswa kwainotarisirwa kweWelding Electrode iyi kwakakosha pakuona kuti mawelds akasimba uye akavimbika mumapurojekiti akakosha ezvivakwa.
