Umbhobho weSpiral ngumbhobho odityanisiweyo odityanisiweyo owenziwe nge-coil yentsimbi ekrwada njengento ekrwada, ekhutshiweyo kubushushu obuqhelekileyo, kwaye idityaniswe yinkqubo yokuwelda i-arc ezenzekelayo enamacala amabini.

Indlela ye-welding ye-arc ye-arc ye-welding ezenzekelayo ifana ne-welding manual kuba isasebenzisa ukhuseleko lwe-slag, kodwa le slag ayikho i-electrode yokugqoka, kodwa i-welding flux inyibilikiswa ngokukodwa.

Uphawu lwendlela ye-welding yombhobho ojikelezayo kukuba: sebenzisa isixhobo sokukhupha kuqala ukukhahlela ubuso bangaphakathi beepleyiti zentsimbi kumacala omabini e-weld engaxutywanga ukuphelisa iiprotrusions ezingalinganiyo kunye nokuqinisekisa ukuba amacala angaphakathi amacwecwe ensimbi kumacala omabini. yeweld engafakwanga icocekile kwaye igudile, kwaye emva koko i-welded.

Kwangaxeshanye, isixhobo sokukhutshwa sikwasetyenziswa njengesixhobo sokubeka intloko ye-welding, oko kukuthi, intloko ye-welding kunye nesixhobo se-extrusion sidityaniswe ngokuqinileyo kunye, kwaye xa isixhobo sokukhupha sihamba ecaleni kwe-weld engafakwanga, kuyaqinisekiswa ukuba intloko ye-welding nayo ichanekileyo ecaleni kwe-Seam engaxutywanga ihamba ukuqinisekisa ukuba intloko ye-welding ihlala iphakathi kwe-seam. Ngale ndlela, inokuqinisekisa ukuba umgangatho we-welds oveliswa yi-welding ngokuzenzekelayo yomgca wemveliso uzinzile kwaye ugqwesileyo, kwaye akukho mfuneko yokulungiswa kwezandla.

Le ndlela ye-welding spiral pipes, okokuqala, iqonda i-automation; okwesibini, idityaniswe phantsi kwe-arc ephantsi kwamanzi, ngoko ukutshintshana kobushushu kunye nokusebenza kokukhusela kunamandla, kwaye umgangatho we-welding uphezulu; okwesithathu Le nzuzo ibangelwa kukuba i-arc ingcwatywe phantsi kwe-flux kwi-arc ye-welding ezenzekelayo.

Umahluko we-arc ye-welding automatic welding yile: i-arc i-arc i-welding automatic i-welding ayisebenzisi i-welding rods, kodwa iingcingo ze-welding, kuba iingcingo ze-welding zinokudliwa ngokuqhubekayo; iintonga ze-welding, kufuneka silahle intloko yentonga ye-welding emva kokutshisa intonga ye-welding, kwaye umsebenzi kufuneka umiswe. Guqula intonga ye-welding kwaye weld kwakhona. Emva kokutshintsha kwi-welding wire, i-welding wire feeding device kunye ne-welding wire reel iya kuqhuba ngokutya i-welding wire. Le ndlela welding kukuba ngokuqhubekayo ukondla i-welding wire kunye nokutshisa i-arc phantsi kwesigqubuthelo se-granular flux enyibilikayo ukwenza i-welding wire kunye nesiseko sesinyithi. Umgodi, ngoko ubizwa ngokuba yi-arc ethotyiweyo yokuwelda.
