Yadda za a bambanta sandar walda mai damp saboda tasirin sandar walda mai damp akan ingancin walda.

Na farko, ana haifar da fasa waldi da pores.

Danshin da sandar walda ke sha ya zama iskar gas a ƙarƙashin aikin zafin walda, wanda ke lalata hydrogen, wanda ke haifar da samuwar fasa walda da pores.Wannan gaskiya ne musamman ga alkaline electrodes.An rufe sandar walda da jakar filastik polyethylene lokacin da aka tattara ta, kuma ba zai iya ba da tabbacin cikakken tabbacin ɗanɗano na dogon lokaci ba.

Na biyu, Ma'auni daban-daban na kaddarorin inji ba su da ƙasa.

Hanya mai sauƙi don duba yanayin damp ɗin sandar walda a wurin:

(1) Duba marufi na sandar walda.Idan marufin ya lalace, sandar walda dole ne ya sha danshi da gaske.

(2) Sanya sandunan walda kaɗan a hannunku sannan ku mirgina su, sandunan walda suka rasa sautin ƙarfe mai ɗanɗano bayan ya sha ɗanshi.

(3) Ɗauki sandar walda kuma lanƙwasa kaɗan da digiri 10-15.Idan akwai sautin tsagewar haske lokacin lanƙwasawa, yana nufin cewa sandar walda ta bushe sosai.

(4) Ɗauki sandar walda zuwa ƙasa kuma ku lura da ƙarfin billarta.Busasshen sanda yana da mafi kyawun billa ƙarfi da haɓakawa mafi girma.

(5) Haɗa lantarki zuwa da'irar walda da gajeriyar kewayawa na ƴan daƙiƙa guda.Idan tururin ruwa ya bayyana a saman rufin, lantarki ne mara bushewa.

(6) Dauki sandar walda don gwajin walda kai tsaye.Idan sandar walda ce mai ɗanɗano, rufin zai fashe ko faɗuwa a cikin tubalan yayin aikin walda, kuma ya haifar da ƙarin tururin ruwa.

(7) Duba saman ƙarshen ƙwanƙwasa walda don ganin ko akwai tsatsa;Zaka kuma iya buga kashe shafi da kuma kai tsaye duba ko waldi core ne tsatsa.

(8) Bincika yayin aikin walda, aikin aiwatar da damp na lantarki zai sami canje-canje masu zuwa:

● A daidai wannan darajar halin yanzu, ƙarfin busa baka ya zama mafi girma kuma zurfin shiga yana ƙaruwa;

●Yawan fantsama yana ƙaruwa kuma ɓangarorin suna ƙara girma;

● Don na'urorin lantarki na acid, murfin slag ba shi da kyau, kuma siffar weld ya zama mara kyau;

● Don ƙananan nau'in nau'in nau'in hydrogen, akwai ƙananan ramuka da yawa akan saman ciki na slag (gefen da ke hulɗa da weld).
