Welding ibasa rakakosha pakuvaka zvinhu zvakawanda zvakagadzirwa nesimbi nealuminium.Kugara kwechimiro chese uye kubudirira kweprojekiti kunowanzoenderana nemhando yeweld.Naizvozvo, kunze kweiyo yakakodzera mhando yemidziyo, iwe zvakare unofanirwa kuziva kuti zvinhu zvega zvinofanirwa kubatana sei.Imwe yemhando dzakasiyana muhurongwa hwese ndeye welding nzira.Nechinangwa cheichi positi, isu tinongotarisa chete pane arc welding ine coated electrodes.
Chii chinonzi manual arc welding?
Iyo yose nzira iri nyore kwazvo.Ndiyo imwe yeanonyanya kufarirwa welding nzira.Inosanganisira kunyungudusa chivharo pamwe chete ne electrode inoshandiswa nezvinhu zvakasungirirwa kuburikidza nearc yemagetsi.Zvizhinji zvezviitwa zvinoitwa nemaoko uye hutano hwebasa hunoenderana neunyanzvi hweanopisa.Nekudaro, pane zvinhu zvekufunga nezvazvo kana iwe uchida kushanda nehunyanzvi.Iwe unofanirwa kutarisa, pakati pevamwe:
yakananga uye inochinjanisa yazvino sosi, kureva yakakurumbira welding muchina
tambo ine electrode inobata
tambo yepasi ine electrode clamp
rudzi rwengowani uye zvimwe zvinhu
Kunze kweiyo welding technique pachayo, kusarudzwa kwe electrode dhayamita ye welded element yakakosha zvikuru.Pasina iyo, kugadzira weld yakanaka hazvigoneke.Chii chaunoda kutarisisa kuti unakirwe nemhedzisiro?
Kusarudza iyo electrode dhayamita yeworkpiece - iwe unofanirwa kuzviziva!
Kusarudzwa kwedhayamita ye electrode yechinhu chakashongedzwa muMMA nzira inotsamira pakukora kweweld kana zvinhu zviri kugadzirwa.Nzvimbo yaunopinza simbi yakakoshawo.Kazhinji, zvinogona kufungidzirwa kuti madhayamita anotangira kubva pa1.6mm kusvika kunyange 6.0 mm.Izvo zvakakosha kuti dhayamita ye electrode haipfuure ukobvu hwezvinhu zvauri kuda kubatanidza.Inofanira kuva duku.Mumabhuku pamusoro pekugadzirisa iwe uchawana ruzivo rwekuti dhayamita ye electrode inofanira kuva yakakura sezvinobvira.Kutama uku ndiko kunonyanya hupfumi.Nokudaro, zvinhu zvine hupamhi hwe 1.5 mm kusvika 2.5 mm zvakanyatsobatanidzwa ne electrode ine chikamu chemuchinjikwa we 1.6 mm.Zvakadini mune zvimwe zviitiko?
Mienzaniso yehukobvu hwezvinhu uye yakakodzera electrode dhayamita.
Kuti utarise zviri nani kusarudzwa kweiyo electrode dhayamita yebasa rekushanda, pazasi iwe uchawana runyoro rupfupi rweanonyanya kufarirwa zvinhu ukobvu uye optimal electrode dhayamita.
Material ukobvu - Electrode dhayamita
1.5mm kusvika 2.5mm - 1.6mm
3.0mm kusvika 5.5mm - 2.5mm
4.0mm kusvika 6.5mm - 3.2mm
6.0mm kusvika 9.0mm - 4.0mm
7.5mm kusvika 10mm - 5.0mm
9.0mm kusvika 12mm - 6.0mm
