Iyo induction preheating muchina inowanzo shandiswa isati yaoma kana welding mamiriro. Kune yekudzima muitiro preheating, chikamu chinoita induction quenching process mushure me preheat kurapwa, inogona kugadzirisa zvinopisa zvikamu deformation dambudziko panguva yebasa rekuita.

  Uyezve, inogona kuderedza kukanganiswa kweworkpiece panguva yekuomeswa kwemaitiro, kunatsiridza kuomeswa kwedhizaini, kuwedzera kuomarara kwedhizaini, kuwana iyo workpiece's yakanakira metallographic chimiro uye yakasara compressive kushushikana, uye kubvisa kutsemuka kunodzima. Preheating for the welding process inogona kudzikisa kutonhora kwekiyi weld kutonhora tembiricha renji, kudzivirira zvakanyanya-kuoma, uye kuderedza ductility ye weld uye kupisa-kukanganisa zone. Inogona kuderedza shrinkage kushushikana kwe weld uye yakatarisana base simbi, kunyanya kune yakakwira-kushushikana welding majoini.
