Don wuraren da ba za a iya sarrafa zafi ba, ana iya ɗaukar matakan kamar amfani da hygroscopics da dumama walda don rage tasirin danshi.
6. Kulawa da kula da inganci:
A kai a kai duba yadda kayan aikin walda ke aiki, kamar mitoci masu kwararar gas, bututun walda, da sauransu, don tabbatar da kyakkyawan yanayin aikinsu.
Ainihin saka idanu akan tsarin walda, kamar yin amfani da tsarin sa ido akan tsarin walda, don ganowa da daidaita ma'auni marasa kyau.
Yi gwaje-gwaje marasa lalacewa (kamar gwajin ultrasonic, gwajin hoto, da sauransu) bayan walda don ganowa da kuma kula da walda mai ɗauke da porosity. Cikakken aikace-aikacen matakan da ke sama na iya rage haɓakar pores a cikin walda na robot da inganta ingancin walda.
Abubuwan da ke haifar da porosity a cikin walda na mutum-mutumi sun haɗa da gurɓatar kayan walda, rashin isassun kariyar iskar gas, rashin sarrafa walda na halin yanzu da ƙarfin lantarki, da saurin walda. Don magance wannan matsala, muna buƙatar ɗaukar matakan da suka dace, ciki har da yin amfani da kayan walda masu tsabta, zaɓin iskar gas mai kariya da dacewa da sarrafa yawan kwarara, saita sigogin walda a hankali, da sarrafa saurin walda bisa ga halin da ake ciki. Ta hanyar magance al'amurra da yawa a lokaci guda kawai za mu iya hanawa da magance matsalar porosity a cikin welds na mutum-mutumi, da haɓaka ingancin walda.
