High zaus ncaj seam welded yeeb nkab (ERW) yog 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 cov ntug ntawm lub raj dawb paug, thiab lub siab vuam nyob rau hauv qhov kev txiav txim ntawm lub nyem cov menyuam kom ua tiav ntau lawm.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 nyob rau hauv lub high-frequency welding txheej txheem yog zoo tswj nrog lub computer tsis siv neeg them nyiaj system, tiv thaiv lub vuam cua sov input zog los ntawm qhov tsawg Qhov tshwm sim txias vuam, virtual vuam thiab overheating tshwm sim los ntawm high heat input zog.
