Mapoka gomba

Panguva yekutsakatika, kudzivirira kwearc uye sla kunopera simba uye zviri nyore kuve prone porosity uye kumwe kukanganisa mu crater.Kuwanda kwekuremara kunogona kubviswa kana iyo inotevera track weld majoini, kubvisa mhedzisiro yezvakanaka kana zvakaipa zvinoenderana nejoinhi kana ichinyunguduka, kunyunguduka kwazvinogoneka, zvakanyanya kubvisa zvachose kukanganisa kwakadaro.Power station boiler inodziya nzvimbo dzinowanzoita calandria kusagadzikana, kusagadzikana muchimiro chechisarudzo chekubatana zvakanyanya munzira apo majoini e crater ye weld ipfupi nguva yekuita, zvakaoma kukunda kukanganisa, zvinogona kutungamira nyore kuburitsa. pombi welded majoini kuonekwa Mapoka maburi

Bvisa maburi

Kana bhuku remagetsi arc welding richikanganisa kutenderera kwekona yekudzivirira kweweld yakakura, kana isiri muwelding process inogara ichichengetedza kona chaiyo, inozokonzeresa gasi rinokuvadza kunze kwekupindira, pasina kuwedzera kweiyo kona yewelding seam kureba, ichagadzira. mhepo inobuda.Kana pamwero mukuru dhayamita mutopota wakagadzirirwa zvose chinzvimbo nomoto musoro nokuda nomoto, nokuda kureba kuitira kuti welder anofanira kutora nomoto zvinzvimbo zvakasiyana panzvimbo dzakasiyana kuitira kuchengetedza kushanda kwekona bhaa.In oblique oblique sandara welding uye pamusoro welding zvinzvimbo, welder muchimiro zvakaoma zvikuru, zvakaoma kuchengeta yakarurama kona mbariro kutumirwa, saka weld nzvimbo idzi dzinowanzoita maburi maburi.Diki dhayamita pombi welding kukanganisa kunoitika zvakanyanya nekuda kwesherufu erection haina kunaka.Kumhanyisa uye swings kutakurwa kunotarisa ukobvu hwebhedhi rimwe chete, kutumirwa nekukurumidza kumhanya kunoita kuti ma electrode ade kukurumidza kuchinja kona, kana kusakwanisa kuumba inoshanda slag = gasi jiviriro yekubatana.Mushure mekudzikisa pasi dzakatetepa-yakavezwa chubhu welding zvinodiwa inovhara yakatetepa, mawoko welding anofanirwa kuchengetedza kukurumidza kwekufambisa, paizobvisa maburi.

Kupinda kusina kukwana

Fin chubhu yakakwenenzverwa majoini anowanzo funga mumutsara mumwe, pamwe newelding shrinkage deformation, zvichikonzera kunetsa kuchengetedza kwakaringana clearance, kana welding yekunyunguduka dhigirii bevel ichipera simba, zvichikonzera kushaikwa kwekupinda.Stainless steel welding consumables yakanyungudutswa simbi inoyerera haina kunaka, uye kupisa nekukurumidza, kupisa hakusi nyore kuisa pfungwa, izvo zvakakonzera kupisa kwearc uye kunyunguduka kwesimbi yepasi kana weld simbi yakanyanya kuoma kuzadza, kuumbwa kwehurema husina kukwana hwekupinda. .Kazhinji hombe dhayamita gobvu rusvingo pombi, majoini kana welding vachitsigira kana kusiri midzi kupinda, kunokonzerwa nokushayikwa pekupinda;hombe dhayamita gobvu-walled chubhu blunt edge yakakura, inogona kukonzera kusakwana kupinda.

Slag

Paunenge uchitengesa, ukobvu hwesimbi yekuzadza huchakanganisa iyo slag inoyangarara kufashukira, hurema hwe slag haugone kupedzwa zvachose kana slag ikaumbwa.Large dhayamita gobvu-walled pombi welding inowanzoshandiswa kana hombe yazvino, iyo yakakura ukobvu hweimwe-pass welding slag inoyangarara zvakanyanya kuoma kugadzira slag kuremara.Liquidity filler metal slag ine simba guru pachizvarwa chekuremara.Simbi isina tsvina yesimbi yakanyungudutswa haina kufamba zvakanaka, pamwe nekushandiswa kwediki ikozvino yakamanikana weld operation, iyo weld simbi solidification, yakaoma kuzara pamusoro weld slag, slag kuumbwa kwehurema.Horizontal welding, soldering oblique welding head inotora lane, lane number seyakabatwa zvisina kunaka, inogona kukonzera weld "yakafa", ine mukana mukuru wekuremara kwe slag.

Mutswe

TIG yakarova pasi seyakaonda, kushushikana kuchaita kuti zviitike kana ichizadza misodzi inokonzerwa nekuumbwa kwekutsemuka;kwete panguva yakakodzera sub-layer backing weld mushure mekugadzira, asiwo chikonzero chekutsemuka.Preheat tembiricha uye zvisina kufanira welding tsvimbo yekuchengetedza, kushandiswa zvisina kunaka, kuchawedzera mukana wekutsemuka.
