Kwicandelo lokwenziwa nokulungiswa kwesinyithi, ukukhetha izinto ezifanelekileyo zokuzalisa kubalulekile ukuqinisekisa ukuthembeka kokuwelda, ukumelana nokugqwala, kunye nokuqina kwamalungu.I-Electrode yokuWelda yeNtsimbi engaGciniyoyi-consumable ekhethekileyo eyenzelwe ukuhlangabezana neemfuno zokudibanisa iintsimbi ezinganyangekiyo kunye neentsimbi ezahlukeneyo. Eli nqaku lihlola iimpawu zobugcisa kunye nokusetyenziswa kolunye uhlobo oludumileyo, i-AWS A5.4 E309-16.
I-electrode ye-A302, ehambelana ne-AWS A5.4 E309-16 specification, luhlobo oluthile lwe-Stainless Steel Welding Electrode. Inesigqubuthelo se-rutile (titanium-calcium) esifakwe kwi-core wire esinomxube we-23% Chromium kunye ne-13% Nickel. Olu hlobo lwesigqubuthelo lubalulekile, njengoko lubonelela ngozinzo oluhle kakhulu lwe-arc kwaye luvumela ukusebenza kakuhle kusetyenziswa imithombo yamandla ye-Alternating Current (AC) okanye i-Direct Current (DC), enika ukuguquguquka kwiimeko ezahlukeneyo zeworkshop kunye nentsimi.
Umsebenzi ophambili wale ntoI-Electrode yokuWelda yeNtsimbi engaGciniyoyenzelwe ukudibanisa iintsimbi ezahlukeneyo. Isinyithi esifakwe kwi-electrode ye-E309-16 yintsimbi engagqwaliyo e-austenitic enomxholo we-alloy ophezulu kuneeklasi eziqhelekileyo ezifana ne-304. Oku kuyenza ifaneleke kakhulu ekudibaniseni ii-overlay zentsimbi engagqwaliyo (i-cladding) kwi-carbon okanye kwi-substrates zentsimbi ezi-low-alloy kunye nokudibanisa iindibaniselwano ezahlukeneyo, i-Type 304 stainless kwi-mild steel. Isinyithi esiphumayo senzelwe ukumelana nokuxutywa kwezinto ezisisiseko, ngaloo ndlela sigcina ukumelana nokugqwala kunye nokuthintela ukwakheka kweentanda.
Iingenelo zokusebenza kwale electrode zinegalelo ekusetyenzisweni kwayo ngokubanzi. I-rutile coating yenza kube lula ukususa i-slag kwaye ivelise iprofayili ye-weld bead egudileyo nethandekayo ngobuhle. Idiphozithi ye-weld ibonisa ukumelana okuhle nokuqhekeka kunye ne-oxidation kumaqondo obushushu aphezulu, nto leyo ebalulekileyo kwiindawo ezivezwe kubushushu obuphezulu okanye inkonzo yobushushu obuphezulu. Ezi mpawu zenza olu hlobo lwe-Stainless Steel Welding Electrode lube lukhetho oluthembekileyo kwizicelo ezibalulekileyo.
Udidi lwe-E309-16, oluboniswe ziimveliso i-electrode ye-A302, lusebenza njengesixhobo esiguquguqukayo nesibalulekileyoI-Electrode yokuWelda yeNtsimbi engaGciniyoUmxholo wayo ophezulu we-chromium kunye ne-nickel, kunye ne-rutile coating esebenziseka lula, yenza ukuba ibe lolona khetho lukhethwayo lokugquma, ukudibanisa iintsimbi ezahlukeneyo, kunye nokugquma ezinye iintsimbi ezine-chromium ephezulu kunye ne-manganese ephezulu. Ukuqonda iipropati ezithile zale Stainless Steel Welding Electrode kuvumela iinjineli kunye nabagqumi ukuba bakhethe eyona ifanelekileyo yokusetyenziswa ukuqinisekisa ukugquma okuhlala ixesha elide, okumelana nokugqwala kwiindawo zoshishino ezifuna kakhulu.
