Intsimbi yesakhiwo eludongeni lwayo ubukhulu, izinto ezilungileyo, iteknoloji yokucubungula kunye nokuzinza, ibe yinto yokuqala yokukhetha kwiprojekthi enkulu ye-oyile kunye negesi yegesi.Kumthungo omkhulu othe tye odityanisiweyo umbhobho wentsimbi isakhiwo esidibeneyo, i-weld kunye nobushushu bendawo echaphazelekayo yeyona ndawo ilula ukuvelisa iziphene ezahlukeneyo, kunye ne-weld undercut, pores, slag, ukungabikho kokudibanisa, ukungabikho kokungena, i-weld, ukutshisa, ukuqhekeka kwe-weld. yeyona ndlela iphambili iziphene welding, kwaye badla ngokuba ngunobangela steel kwesakhiwo umgangatho iingozi imvelaphi.

Amanyathelo okulawula umgangatho wentsimbi yesakhiwo aquka:

Ngaphambi kokulawula umgangatho we-welding

1. Yenza umgangatho omhle wezinto eziluhlaza, emva kokudlula ukuhlolwa ngaphambi kokungeniswa ngokusemthethweni kwindawo yokwakha, kwaye ngokuqinisekileyo uphelise ukusetyenziswa kwentsimbi ekumgangatho ophantsi.

I-2, Ilandelwa kulawulo lwezixhobo ze-welding.Khangela ukuba izixhobo zokuwelda kwiimveliso eziqeqeshiweyo, ukugcinwa kunye nenkqubo yokubhaka ukuba ziphunyeziwe, nokuba zikhupha umphezulu we-welding ucocekile kwaye awunamhlwa, ukugquma kwe-electrode kukhuselekile, kunye okanye ngaphandle kokungunda.

I-3, indawo ye-Welding yolawulo olucocekileyo.Umgangatho ococekileyo wokuhlola i-weld zone, ngaphandle kwamanzi, i-oyile, i-rust kunye nefilimu ye-oxide engcolileyo, oko kukuthintela iziphene ze-weld zangaphandle zivelisa indima ebalulekileyo.

I-4, Khetha indlela efanelekileyo ye-welding kufuneka iphunyezwe kuqala ukuhlolwa kwe-welding, emva kwemigaqo ye-welding.

Ukulawulwa komgangatho kwinkqubo ye-welding

I-1, ngokwenkqubo ye-welding, i-wire kunye nophononongo lwe-flux ichanekile, thintela ukusetyenziswa kakubi kocingo kunye ne-flux ebangelwa yi-welding quality ngozi.

I-2, indawo yokulawula i-welding, thatha amanyathelo afanelekileyo emva kwe-welding xa indawo ye-welding ingekho kakuhle (ubushushu obungaphantsi kwe-0℃, ukufuma okunxulumeneyo okungaphezulu kwe-90%) kufuneka kube.

3, Ngaphambi kovavanyo lokuqala olulindelekileyo imilinganiselo ye-weld groove, kubandakanywa indawo, i-edge ebomvu, i-engile kunye nomlomo ongalunganga, njl.njl ihlangabezana neemfuno zenkqubo.

I-4, Ngaphakathi nangaphandle kwenkqubo yokudibanisa i-arc ekhethiweyo yangoku, i-welding voltage, isantya se-welding kunye nezinye iiparitha zichanekile.

5. Ukongamela abasebenzi kwi-arc ye-arc entywilayo ngaphakathi nangaphandle kwe-arc ye-welding epheleleyo ye-tube yentsimbi yokuphela kwepleyiti yobude, intsimbi yomthungo eqondileyo yomeleza ukusebenza kwe-arc ye-welding xa iipleyiti zangaphakathi nangaphandle, ezinceda ekuphuculeni umgangatho we-welding. umbhobho uphela.

I-6, Lawula abasebenzi be-welding kwi-welding slag ecocekileyo nokuba ngaba kuqala, nokuba i-joint iqhutywe ngokupheleleyo, ingaba i-groove yeoli, i-rust, i-slag, amanzi, ipeyinti kunye nezinye izinto ezingcolileyo.
