FAQ: Game da Batir Spot Welding Spatter
Tambaya: Me yasa spatter ke faruwa a Cu -Albatir tabo walda?
A: Spatter yawanci yana faruwa ne lokacin da ƙarfin walda ya yi yawa, ƙarfin lantarki bai isa ba, ko saman aluminum yana da fim ɗin oxide ko gurɓatawa. A cikin Cu{1}Alwelding, aluminum yana narkewa da wuri fiye da jan ƙarfe, don haka rashin kulawar matsi na iya haifar da narkakkar aluminum daga wurin walda.
Tambaya: Ta yaya zan iya rage baƙar fata a kusa da walda?
A: Blackening is often caused by surface oil, oxide film, overheating, or electrode contamination. Cleaning the copper and aluminum surfaces, shortening excessive pulse time, improving electrode cooling, and maintaining electrode tips can help reduce black rings around the weld.
Tambaya: Shin na'urar fitarwa ta capacitor ya dace da sassan baturi na jan karfe{0}}?
