ASTM A513 simbiipombi nechubhu zvesimbi yekabhoni ne alloy zvakagadzirwa nesimbi inoputirwa nekupisa kana inotonhorera sezvinhu zvakagadziriswa ne resistance welding (ERW), iyo inoshandiswa zvakanyanya mumhando dzese dzezvivakwa zvemakanika.
Rudzi rwekutanga runogona kukamurwa kuita 1a ne1b.
Rudzi 1a (AWHR): "yakasungirirwa" kubva musimbi inopetwa nemoto (ine chikero chemugayo).
Rudzi urwu rwepombi runosungirirwa zvakananga kubva musimbi inoputirwa nekupisa ine iron oxide (chikero chemugayo) inoumbwa panguva yekumonera. Rudzi urwu rwepombi runowanzo shandiswa mukushandiswa uko kusimba kwepamusoro kusina kukosha nekuti pamusoro payo pane chikero chemugayo.
Rudzi 1b (AWPO): "yakasungirirwa" kubva musimbi yakaputirwa nemafuta yakakangwa nekupisa (chikero chemugayo chabviswa).
Rudzi urwu rwepombi runosungirirwa kubva musimbi inoputirwa nekupisa yakanyungudutswa uye yakazorwa mafuta uye inozivikanwa nekubviswa kwechiyero chemugayo. Kugadziriswa kwepombi nemafuta hakungobvisi chete oxidation yepamusoro asiwo kunopa dziviriro yengura uye mafuta panguva yekugadzirisa, zvichiita kuti pombi iyi ive yakakodzera kushandiswa kunoda nzvimbo yakachena kana mamiriro ekugadzirisa akaomarara zvishoma.
