Habka daawaynta shilalka birta dhalaalaysa ee foornada birta dhalada ah

Shilalka birta dareeraha ah ee dareeraha ah waxay si fudud u sababi karaan waxyeello qalabka waxayna xitaa khatar gelin karaan bini’aadamka. Sidaa darteed, waxaa lagama maarmaan ah in la sameeyo dayactirka iyo dayactirka foornada intii suurtagal ah si looga fogaado shilalka dareeraha dareeraha ah ee birta.

Marka gambaleelka alaarmiga uu dhawaaqo, isla markaaba jar korontada oo hubi jidhka foornada si aad u hubiso in birta dhalaalaysa ay dibadda u soo baxayso. Haddii uu jiro wax daadanaya, isla markiiba foornada ku tuur oo dhame shubista birta dhalaalaysa. Haddii aysan jirin wax daadasho ah, hubi oo ula macaamil si waafaqsan nidaamka kormeerida alaarmiga foornada. Haddii la xaqiijiyo in birta dhalaalaysa ay ka soo daadato dahaarka foornada oo ay taabato electrode-ka si ay u keento digniin, birta dhalaalaysa waa in lagu shubaa, daboolka foornada waa in la hagaajiyaa, ama foornada waa in dib loo sameeyaa.

Birta dhalaalaysa waxa sababa burburka dahaarka foornada. Dhumucdiisuna waxay sii yaraanaysaa dahaarka foornada, waa ay korodhaa waxtarka korantada oo aad u dhaqso badan heerka dhalaalka. Si kastaba ha noqotee, marka dhumucda foornada foornada ay ka yar tahay 65 mm ka dib xirashada, dhammaan dhumucda foornada foornada ayaa had iyo jeer ah lakab adag oo adag iyo lakabka kala-guurka. Ma jiro lakab dabacsan, dildilaacyo yaryar ayaa dhici doona marka dahaarka wax yar loo dhigo qaboojin degdeg ah iyo kuleyl. Dildilaaca wuxuu geli karaa dhammaan dahaarka foornada wuxuuna si fudud u sababi karaa in birta dhalaalaysa ay dibadda u soo baxdo.

Dhisidda foornada aan caqligal ahayn, dubista, hababka sintering, ama xulashada aan habboonayn ee alaabta dahaarka foornada, daadinta foornada waxay ku dhici doontaa dhowrka foornooyinka ugu horreeya ee dhalaalidda.
