I electric-welding njani umbhobho steel?

Apho umbhobho isetyenziswa namhlanje, Steel yombane-welding? Le mveliso, nto leyo kwiimeko mihla lisetyenziswa-mveliso eyahlukeneyo.

isicelo

Ngokubanzi, ibekwe apho kuyimfuneko ukuthutha into elulwelo okanye sukube abanesidanga eliphezulu ubuvila. Ngoko ke, ityhubhu le hlobo inokufumaneka kubunjineli, ngokuba ukubeka ukufudumeza umaleko engundoqo.

pipe steel zombane-welding asetyenziswe kolu shishino. Ngaphandle kokuba uyakwazi ukwenza kunye banikwe ioli, ulwakhiwo, ekwenziweni ifanitshala okanye ezemidlalo nabaqeqeshi. yokusebenza kwalo, intsebenzo entle, amathuba amahle ukuwelda (kuquka ikhaya) uyakwazi ukulisebenzisa iimeko zokuphila lokuqulunqa kunye nokulungiswa lothungelwano zobunjineli.

zobukhulu

Kagesi welding Imibhobho ephakathi yentsimbi, nto leyo eye GOST 10704-91 nani, ukuvelisa ubude ethile random ukuba enobubanzi ethile. Umzekelo, ukuba ixabiso yokugqibela ka-0.3 cm imveliso kufuneka ungabi ngaphantsi kwe-2 ubude, kwaye ukuba oku mkhulu 15.2 cm, ngeke ibe ngaphantsi kwe m 5 ubude. Kwakhona, kukho kwahluka-mbini xa ubude ukuba ubukhulu elinikiweyo pipe na ibanga elithile. Ngoko ke, ukuba isibonisi nqaku ubungakanani 7 cm zingaqala iimitha ezi-5 ukuya ku-9.

production

Ziziphi iimpawu umbhobho onjalo kufuneka? electric-welding Steel loguqulelo kwi imveliso kufuneka izicwangciso ezithiywe iimfuno karhulumente ukuze amanqaku ezisetyenziswe kulo okanye kwinqanaba. Umzekelo, imibhobho ukuba oyile negesi imibhobho (trunk) yenziwa ngokwe GOST 20295-85. Bona akhiwa le arc welding okanye uhlobo qhagamshelana (le yokugqibela kunye kwemisinga eliphezulu-frequency) ezineeklasi amandla ezahlukeneyo (ukusuka K34 ukuya K60).

Lokuvelisa iimveliso ezisetyenziswayo okanye thermally baphathwe zentsimbi shushu liqengqiwe (ekhululekile okanye semi-wambulala) kunye okuqulethwe C (carbon) ayikho ngaphezu kwe-0.2% ngokobunzima. amaphepha alo ezibhijeleyo ityhubhu, emva koko amagophe sheets ebushushwini babo kunye rolls uwathandabuze yangoku (amakhonkco electrode). Izinga iinkqubo ezinjalo koomatshini ezikhethekileyo kunokuba kakhulu phezulu (amashumi iimitha ngomzuzu ye welding, kuxhomekeke Ebubanzini bodonga). Umsebenzi phantse lonke sikhatshwe nangokukrola imveliso ubude efunekayo usebenzisa izixhobo slotted.

Steel electric-welding, uyakwazi ukufumana unyango ubushushu ezifana lonke ubude, kwaye kuphela ukuba weld. Kwi isiseko iimveliso yesinyithi awavumelekanga ukuba kuthinjwa, iziphako, iintanda, kwelanga kunye iinyanda. iziphene eyamkelekileyo surface level akufuneki ukulungiswa ukuwelda (atshayele kuphela) ukwenzela ukugcina iqondo efunekayo kukuthembeka imveliso. amalungu nge welding, kufuneka ibe amahlwempu fusion uqhekeke, pores, fistulas, inclusions zeBlack leyo eza kumphezulu.

iindleko

Njengokuba kude Imibhobho ephakathi yentsimbi indlela kagesi welding? Ixabiso kubo, kuxhomekeke kumenzi, i-grade sentsimbi, le ubukhulu kunye nodonga ubukhulu ziyahluka ukusuka 32 ukuya 45-48 amawaka. Xa uthenga kufuneka usoloko sinikele ingqalelo ukuthobela kunye nemigangatho karhulumente, oko kukuthi. To. Xa sikhokelo, iimveliso kudlule iimvavanyo ezifunekayo, kuquka icandelo uchebe, amandla ifuthe kwiqondo lobushushu ezahlukeneyo, uqine yesihloko okweqanda, ecaleni ubude, umgangatho metal welding, edibeneyo, kunye nabanye.

Ukuze ufumane inkcazelo malunga nokuba siyintoni na imveliso icetyelwe ukuba uthenge, sinokufunda uphawu ityhubhu. Kufuneka ukuba athwale kumgama 10-150 cm ukusuka kwelinye icala, ziphawulwe ngepeyinti kwaye ziquka nonyaka esenziwe ngawo, data yolawulo zobugcisa, ibakala sentsimbi, inombolo umbhobho ngamnye (ibhetshi), luphawu umenzi.
