Uphose welding iron

Iron - kukuthi, njengoko esaziwa, intsimbi kunye carbon ingxubevange. Umxholo wokugqibela kufuneka ibe ngaphezu ekhulwini ezimbini. Kuxhomekeka kwimeko apho ingxubevange le carbon, ukwahlula engwevu ezimhlophe iintlobo elingqukuva yentsimbi. Xa uhlobo lokuqala ikhabhoni ngohlobo grafayithi, ngokwaseburhulumenteni free, eyikhethayo machinability yayo elungileyo. Ekubeni cast intsimbi emhlophe, lwesi sakhi sikwimo wambopha, kuba nzima ukuba weld. Ekuveleni zokufunda kukukhanya ngombala.

Njani na iwelding kwesinyithi? Masiqalise nesibakala sokuba le nto - hayi ofanele kakhulu olu hlobo lonyango. Xa segesi oko deforms kwaye ngokulula neentanda. Oku kungenxa isakhiwo eyodwa kwekhabhoni zaphuka yayo. Ogalelwe ioli ube mnye kwesinyithi, kwakunye nabo baye unenzondelelo sesichengeni kumajelo ezahlukeneyo bako, ayikwazi omthuqwa. Oku, ke, iindidi efanelekileyo ukuba olungisiweyo nezelinen umbala ukukhanya hina. Segesi nsimbi iziphumo ebezingalindelekanga: ezingwevu yaye ngenxa yoko, xa kukuvela ukwenza ekuhlaleni ukuwelda umaleko intsimbi ezimhlophe Ongayinikeliyo ngokwayo ukuba akukho unyango; Njengoko sele kukhankanyiwe, ukuyilwa lwamathanda; ukwandisa ombane kwindawo iwelding; echibini metal weld inokuba aneentunja ngenxa carbon nokudinwa kunye kumiswa ngaxeshanye carbon dioxide. Ngenxa yoko, le nkqubo ubangela kobunzima obuninzi. Kodwa welding kwesinyithi isetyenziswa kakhulu ngokubanzi. It has ngeendlela ezintathu eziphambili: ukubanda nobushushu ukuze semi.

Kuqala ke ukungabikho preheating. welding Cold elingqukuva intsimbi wenziwe ngentsimbi, isinyithi waphosa wayenza zesinyithi non-ayoni kunye aluminium electrode. Eyona nto iphambili kule - ukunqanda ubushushu kakhulu kwindawo ubushushu-abachaphazelekayo. Ngokuba lo steel electrode usebenzisa umaleko electrode lokuqala superposed omncinci ezinomthamo encinane carbon, yayisoma obhityileyo. Kul kweli nqanaba mayingagqithi amps 90. maleko elandelayo ke superposed electrode ye ubukhulu enkulu, ukutyabeka isenokuba mhlawumbi obhityileyo okanye zamafu.

Enye ulawulo ebalulekileyo - amalungu ebuntsimbi kufuneka bafake izicelo kunye iziphazamiso embalwa ukuba shushu-abachaphazelekayo lobushushu zone awudluli izidanga zaba ngamashumi omathandathu.

Ukuba welding kufuneka izakwenziwa iindawo ezibalulekileyo, ngoko unga sebenzisa icebo okhethekileyo. Oku njalo-ebizwa vvertyshi - amaqhosha ebhutsi ezizodwa, ezenziwe yesinyithi esiphakathi. injongo yazo - ukudibanisa metal weld kunye yentsimbi. Welding lwenziwa kuqala, ngeenxa zonke kubo, uze - ngendlela eqhelekileyo. Xa kuyimfuneko ukuba weld naziphi na iziphene, ongasilandeliyo thina, ehlola kunye nezinye ubuthathaka, wayedla electrode ezenziwe aluminium ngokusekelwe nickel okanye ubhedu. Ukukhuthaza graphitization, Iziphepha ukuvela indawo ebanzi mhlophe. Segesi intsimbi ekhaya ikakhulu wavelisa indlela ebandayo. Oku kusetyenziselwa nayiphi na iintlobo electrode zikhankanywe ngasentla.

welding intsimbi Hot ibandakanya ngokushushubeza le workpiece phambi kokuba ukusebenza nayo. Loo indlela kusehla ombane yesakhiwo yesinyithi. Kuba indlela semi - yi kancincane eshushu. It is a ezibengezelayo graphitization kunye zokufudumeza jikelele okanye wengingqi ukuya kwiqondo elithile. Ezi ndlela asetyenziswa ngeendlela ezahlukeneyo.

Ukuba ufuna ukwenza i welding wamalungu mntu wenza elingqukuva intsimbi, kwimeko apho ukusetyenziswa indlela iwelding ebandayo. Ukuba umsebenzi oluqhutywa phaya kwisityalo, ngendlela engazange mveliso, sebenzisa indlela eshushu.
