Shiri kafin walda

Aikin shirye-shiryen kafin waldawa yana da mahimmanci kamar tsarin waldawa, wanda ke da alaƙa kai tsaye da ingancin walda da tasirin ƙãre samfurin.

1. Electrode bushewa

Manufar bushewar wutar lantarki kafin waldawa ita ce cire danshin da ke cikin jik ɗin lantarki da rage hydrogen ɗin da ke cikin narkakkar tafki da walda don hana ƙura da fashewar sanyi.Tsarin bushewa na lantarki tare da nau'ikan sutura daban-daban ya bambanta, kuma ana aiwatar da tsarin bushewa bisa ga tsarin da aka kayyade a cikin littafin koyarwa na lantarki.Ana ba da shawarar bushewa bisa ga fakitin umarnin walda na Tianqiao.

2. Tsaftace kafin walda

Yana nufin kawar da mai, tsatsa, fenti da ruwa a saman ramin haɗin gwiwa da kewaye (a cikin kimanin 50mm) kafin walda.Lokacin waldawa tare da na'urori na alkaline, buƙatun tsaftacewa suna da tsauri kuma cikakke, in ba haka ba ana iya haifar da pores da tsagewar da aka jinkirta.Acid electrodes ba su da matukar damuwa ga tsatsa.Idan tsatsa yana da ɗan haske kuma ingancin weld ɗin bai yi girma ba, ƙila ba za a cire shi ba.

3. Preheating

Yana nufin matakan tsari don dumama gaba ɗaya ko ɓangaren walda da kyau kafin waldawa.Babban manufarsa ita ce rage yawan sanyaya na haɗin gwiwa bayan waldawa, guje wa tsara tsarin da aka taurare, da rage damuwa na walda da lalacewa.Hanya ce mai inganci don hana fasa walda.Bukatar preheating da matakin zafin jiki na zafin jiki ya dogara da kaddarorin ƙarfe na tushe, lantarki da aka yi amfani da shi da kuma hana haɗin gwiwa.

Don tsarin gaba ɗaya na ƙananan ƙarfe mai ƙarancin carbon da ƙaramin ƙarfe mai ƙarfi mai ƙarfi tare da ƙananan matakan ƙarfi, gabaɗaya ba a buƙatar preheating.Duk da haka, don tsarin da babban rigidity ko matalauta weldability da suke yiwuwa ga fasa, preheating da ake bukata kafin waldi.Kayan walda tare da haɓakar zafin jiki mai ƙarfi, irin su jan karfe, aluminum da alluran su, wani lokaci suna buƙatar preheating, wanda zai iya rage ƙarfin walda da haɓaka zurfin shigar ciki, sannan kuma sauƙaƙe haɗakar ƙarfen walda da ƙarfen tushe.

Dole ne a nuna cewa walƙiya preheat ba kawai amfani da makamashi ba ne, ƙarancin yawan aiki, amma har ma da yanayin aiki mara kyau.Ya kamata a yi walda ba tare da preheating ko ƙarancin zafin jiki ba a duk lokacin da zai yiwu.Yin amfani da ƙananan na'urorin lantarki irin na hydrogen na iya rage zafin zafin jiki na preheating, saboda kyakkyawan juriya mai kyau, amma abun ciki na ruwa na lantarki dole ne ya zama ƙasa sosai.Matukar an ba da izini, za a iya zabar wutar lantarki bisa ka'idar ƙarancin haɗin gwiwa, wato ƙarfin ƙarfen da aka ajiye ya yi ƙasa da na ƙarfen tushe, kuma robobi da taurin wutar lantarki sun fi haka. na tushe karfe don walda, don haka preheating zafin jiki za a iya rage ko ba za a iya amfani da preheating.
