High-frekans kouti dwat elektrik-rezistans soude tiyo asye (erw tiyo asye) se cho-woule bobin apre fòme machin, itilize nan segondè-frekans aktyèl efè po ak efè pwoksimite, chofaj la kwen tib ak k ap fonn, peze roulo anba presyon soude reyalize pwodiksyon an.

High-frekans rezistans soude tiyo asye, tiyo soude ak pwosesis soude òdinè se pa menm bagay la tou, se soude a te fè nan fonn metal la baz soti nan kò a, fòs la mekanik se pi bon pase tiyo jeneral la. Lis aparans, segondè presizyon, pri ki ba soude wo ak ti, favorab 3PE kouch anti-korozyon. Gen diferans enpòtan nan metòd yo soude ant segondè frekans tiyo soude ak submerged arc soude tiyo. Kòm soude a fè imedyatman nan gwo vitès, difikilte pou asire bon jan kalite a nan soude se pi wo pase sa yo ki nan submerged arc soude.
