Ubukhulu bodonga lwe-Diameter ye-LSAW yombhobho omkhulu kunye nezinto zayo ezinkulu, ezilungileyo, uzinzo lwenkqubo, ibe lukhetho lokuqala lweprojekthi enkulu ye-oyile yasekhaya neyangaphandle kunye nombhobho wegesi. Kumthungo omkhulu othe tye wantywiliselwa umbhobho odityanisiweyo we-arc, i-weld kunye nobushushu bommandla ochaphazelekayo unokuvelisa iintlobo ezahlukeneyo zokungafezeki kwe-undercut edityanisiweyo, i-porosity, i-slag, ukungabikho kokudibanisa, ukungabikho kokungena, i-weld, ukutshisa iintanda ze-welding uhlobo oluphambili iziphene welding, kwaye badla ngokuba yimvelaphi ethe tye umthungo entywiliselwe arc welded umbhobho iingozi umgangatho.
Amanyathelo okulawula umgangatho: 1, ngaphambi kokulawulwa komgangatho we-welding 1) Okokuqala, yenza umgangatho omhle wezinto eziluhlaza, emva kokudlula ukuhlolwa ngaphambi kokuba ungene ngokusemthethweni kwindawo yokwakha, kwaye uzimisele ukuphelisa ukusetyenziswa kwentsimbi engaphantsi kwe-2) elandelwa yi. ulawulo lwezixhobo ze-welding. Khangela ukuba izixhobo zokuwelda kwiimveliso eziqeqeshiweyo, ukugcinwa kunye nenkqubo yokubhaka ukuba zenze, nokuba zikhupha i-weld surface ecocekileyo kwaye ingenamhlwa, i-electrode coating ilungile, kunye okanye ngaphandle kokungunda. 3) Kwakhona, ulawulo lwendawo ye-weld ecocekileyo. Ukucoca indawo ye-weld ye-QA, ngaphandle kwamanzi, i-oyile, i-rust kunye nefilimu ye-oxide engcolileyo, oko kukuthintela iziphene ze-weld zangaphandle zivelise indima ebalulekileyo. 4) Khetha indlela yokudibanisa efanelekileyo kufuneka iphunyezwe kuqala ukuhlolwa kwe-welding, emva kwemigaqo ye-welding. I-2, ukulawulwa kwekhwalithi ye-welding 1) ngokwenkqubo ye-welding iinkcukacha ze-wire kunye nokuhlaziywa kwe-flux ichanekile, ukukhusela ukusetyenziswa kakubi kwe-welding wire kunye ne-flux ebangelwa umgangatho wengozi. 2) ukubeka iliso kwindawo ye-welding, thatha amanyathelo afanelekileyo emva kwe-welding xa imeko ye-welding ingekho kakuhle (ubushushu obungaphantsi kwe-0 ℃, ukufuma okuhambelanayo okukhulu kuno-90%) kufuneka kube. 3) phambi kovavanyo lokuqala olulindelekileyo imilinganiselo welding groove, kuquka indawo, emphethweni blunt, nokuba i-engile kunye nezibuko engalunganga ukuhlangabezana neemfuno zobugcisa. 3 5) ukulawulwa kwabasebenzi kwi-arc ye-arc ye-arc entywilayo ngaphakathi nangaphandle i-welding yentsimbi yombhobho inzuzo epheleleyo yobude beplate yokuphela kwe-arc ubude, ukuqinisa ukusebenza kakuhle kwe-arc ye-welding xa iipleyiti zangaphakathi nangaphandle, ezinceda ukuphucula umgangatho we-welding umbhobho uphela. . 6) ukubeka iliso kwabasebenzi kwi-welding slag welding ukuba baqale bacocwe, nokuba sele ucociwe ngokupheleleyo kwi-joint groove malunga nokuba kukho i-oyile, irusi, i-slag, amanzi, ipeyinti kunye nezinye izinto ezingcolileyo.
