1. Process musimboti
Electrode arc welding inzira yearc welding inoshandisa mawoko inoitwa welding tsvimbo.Chiratidzo chechiratidzo E che electrode arc welding uye nhamba yenhamba 111.
Iyo welding process ye electrode arc welding: kana welding, iyo welding tsvimbo inounzwa kusangana neiyo workpiece pakarepo mushure mepfupi wedunhu, ichibatidza arc.Iyo tembiricha yepamusoro yearc inonyungudusa zvishoma iyo electrode uye workpiece, uye yakanyunguduka musimboti shanduko kuenda kune yakanyungudika zvishoma yakanyungudutswa workpiece muchimiro chekudonha kwakanyungudutswa, iyo inosanganiswa pamwechete kuita dziva rakanyungudutswa.Iyo welding electrode flux inogadzira imwe huwandu hwegasi uye mvura slag panguva yekunyunguduka, uye gasi rinogadzirwa rinozadza arc nenzvimbo yakatenderedza yedziva rakanyungudutswa, ichiita basa rekuparadzanisa mhepo kuchengetedza simbi yemvura.Liquid slag density idiki, mudziva rekunyunguduka rinogara richiyangarara, rakafukidzwa nesimbi iri pamusoro, kuchengetedza basa resimbi yemvura.Panguva imwecheteyo, iyo flux ganda rinonyungudutsa gasi, slag uye kunyungudutsa weld core, iyo workpiece inoteedzana yemetallurgical reactions kuti ive nechokwadi chekuita kweiyo weld yakaumbwa.
2. Zvakanakira electrode arc welding
1) Zvishandiso zviri nyore, kugadzirisa kuri nyore.Iyo AC uye DC welding michina inoshandiswa pa electrode arc welding iri nyore uye haidi yakaoma yekubatsira michina yekushanda kwetsvimbo yewelding, uye inongoda kuve yakashongedzerwa nematurusi ekubatsira ari nyore.Iyi michina yewelding iri nyore muchimiro, yakachipa uye iri nyore kuchengetedza, uye mari mukutenga michina yakaderera, chinova chimwe chezvikonzero zvekushandisa kwayo kwakafara.
2) Hapana yekubatsira gasi kudzivirira kunodiwa, iyo welding tsvimbo haingopi simbi yekuzadza, asi inokwanisawo kugadzira gasi rekudzivirira kuchengetedza dziva rakanyungudutswa uye weld kubva kune oxidation panguva yewelding process, uye ine chaiyo yakasimba mhepo inopikisa.
3) Flexible kushanda uye kusimba kwakasimba.Stick arc welding yakakodzera kukwenenzvera zvimedu zvimwechete kana mabhechi madiki ezvigadzirwa, zvipfupi uye zvisina kujairika, zvakagara zviri munzvimbo uye mamwe seam welding izvo zvisiri nyore kuwana mechanized welding.Welding inogona kuitiswa chero kupi uko iyo welding tsvimbo inogona kusvika, nekuwanikwa kwakanaka uye kuchinjika kushanda.
4) Yakasiyana-siyana maapplication, akakodzera kukwenenzvera masimbi mazhinji emaindasitiri uye alloys.Sarudza iyo chaiyo welding tsvimbo haigone chete weld kabhoni simbi, yakaderera alloy simbi, asiwo yakakwirira alloy simbi uye isina-ferrous simbi;haingogone chete kupinza simbi imwe chete, asiwo inogona kupinza simbi dzakasiyana, asi zvakare kukanda simbi inokwenenzverwa kugadzirisa uye zvakasiyana siyana zvesimbi senge overlay welding.
3. kuipa kwe electrode arc welding
1) ma welder anoshanda tekinoroji zvinodiwa akakwira, iwo ma welder kudzidzisa mari.Welding mhando ye electrode arc welding mukuwedzera pakusarudzwa kweakakodzera welding maelectrode, welding process parameters uye welding equipment, kunyanya nema welders mashandisirwo ekushandisa uye ruzivo rwekuona kuti kunaka kwewelding ye electrode arc welding kusvika pamwero wakati unotemwa nemawelder anoshanda. maitiro.Naizvozvo, ma welders anofanirwa kudzidziswa kazhinji, mari yekudzidzira inodiwa yakakura.
2) Mamiriro ezvinhu asina kunaka ebasa.Stick arc welding inonyanya kutsamira pane manyorero ekushanda kweanopisa uye kutarisa kweziso kuti apedze maitiro, kusimba kwevashandi ve welder.Uye nguva dzose munzvimbo yakakwirira yekubikira uye muchetura fume nharaunda, mamiriro evashandi ane hurombo, saka kusimbisa kuchengetedza kwevashandi.
3) Kuderera kwekugadzira kushanda zvakanaka.Welding tsvimbo arc welding inonyanya kutsamira pakushanda kwemanyorero, uye welding process paramita kusarudza diki renji.Uye zvakare, iyo welding electrode inofanirwa kuchinjwa kazhinji, uye welding chiteshi slag kuchenesa kunofanirwa kuitwa kazhinji, kana ichienzaniswa neatomatiki welding, kugadzirwa kwewelding kwakadzikira.
4) Hazvishande kune dzakakosha simbi uye dzakatetepa plate welding.Kune simbi dzinoshanda uye simbi dzisina kunyungudika, nekuti simbi idzi dzinonzwa zvakanyanya nekusvibiswa kweokisijeni, kuchengetedzwa kwe electrode hakuna kukwana kudzivirira oxidation yesimbi idzi, mhedzisiro yekudzivirira haina kunaka zvakakwana, iyo welding mhando haina kuzadzisa zvinodiwa. saka haugone kushandisa electrode arc welding.Low melting point masimbi uye alloys adzo haagone kusungwa ne electrode arc welding nekuti tembiricha yearc yakawandisa kwavari.
4. Chikumbiro chekushandisa
1) Inoshanda kune ese-chinzvimbo welding, workpiece ukobvu pamusoro pe3mm
2) Weldable simbi siyana: simbi inogona welded zvinosanganisira kabhoni simbi, yakaderera alloy simbi, Stainless simbi, kupisa kusapinda simbi, mhangura uye alloys ayo;masimbi anogona kugadzirwa asi anogona kupiswa, mushure-anopisa kana zvese zvinosanganisira simbi yakakandwa, simbi yakasimba, simbi yakadzima, nezvimwewo;simbi inonyungudika yakadzika isingagone kusungwa seZn/Pb/Sn nemaaloyi ayo, simbi dzisinganyungudika dzakadai seTi/Nb/Zr, nezvimwe.
3) Yakanyanya kukodzera chigadzirwa chimiro uye chimiro chekugadzirwa: zvigadzirwa zvine zvimiro zvakaoma, zvine nzvimbo dzakasiyana siyana, welds isingaite mechan kana otomatiki;single-mutengo kana yakaderera-vhoriyamu welded zvigadzirwa uye kuisa kana kugadzirisa madhipatimendi.
