High zaus ncaj seam welded yeeb nkab (ERW) yog cov kub dov coil phaj tsim los ntawm lub tshuab tsim, siv cov nyhuv ntawm daim tawv nqaij thiab cov nyhuv sib thooj ntawm cov zaus tam sim no kom sov thiab yaj lub ntug ntawm lub raj dawb paug, thiab siab welding nyob rau hauv qhov kev txiav txim ntawm lub nyem rau cov khoom. Txoj kev ua haujlwm siab welding tau siv rau kev tsim cov kav dej hauv xyoo 1950s. Hauv kaum xyoo dhau los, nws cov thev naus laus zis ntau lawm tau dhau los ua qhov zoo tshaj plaws, thiab cov khoom lag luam tau raug txhim kho tas li. Thawj yog qhov zoo ntawm cov khoom siv raw siv hauv ERW ntau lawm tau txhim kho zoo.

Qhov thib ob, kev tswj tsis siv neeg lub computer yog pom tau hais tias nyob rau hauv cov txheej txheem ntawm loj thiab nruab nrab-caliber ERW steel yeeb nkab tsim vuam kev kho cua sov, thiab lub tshav kub input zog thaum lub sij hawm lub high-frequency welding txheej txheem yog zoo tswj nrog lub computer tsis siv neeg them nyiaj system, tiv thaiv lub vuam tshav kub input zog los ntawm tsawg Lub resulting txias welding, virtual welding los ntawm high-frequency vuam txheej txheem.
