ASTM A513 simbiiyo kabhoni uye alloy simbi pombi uye chubhu yakagadzirwa kubva inopisa-yakakunguruswa kana inotonhora-yakakungurutswa simbi seyakasvibira neresistance welding (ERW) process, iyo inoshandiswa zvakanyanya mumhando dzese dzemakina zvimiro.
Rudzi rwekutanga runogona kukamurwa kuita 1a uye 1b.
Type 1a (AWHR): "se-welded" kubva kune inopisa-yakaputirwa simbi (ine mill scale).
Iyi fomu yepombi inosungwa zvakananga kubva kune inopisa-yakakungurutswa simbi ine iron oxide (mill scale) inoumbwa panguva yekukunguruka.Iyi mhando yepombi inowanzoshandiswa mumashandisirwo apo kutendeseka kwepamusoro hakukoshese nekuti nzvimbo yacho ine mill scale.
Type 1b (AWPO): "se-welded" kubva kune inopisa-yakaputirwa yakanyungudutswa uye simbi yemafuta (mill scale yakabviswa).
Iyi fomu yepombi inosungirirwa kubva kune inopisa-yakaputirwa simbi yakabikwa uye yakazora uye inoratidzwa nekubviswa kweguyo.Iyo pickling uye mafuta ekuzora haingobvisi oxidation yepasi chete asi inopa imwe dziviriro yekuora uye mafuta panguva yekugadziriswa, zvichiita kuti pombi iyi ive yakakodzera kune maapplication anoda nzvimbo yekuchenesa kana kuomesa zvishoma.
