1. Cov yeeb nkab welded yog ib puag ncig cov yeeb nkab welded los ntawm lub phaj, uas tau muab faib ua high-frequency resistance welded yeeb nkab (ERW welded yeeb nkab), longitudinal arc welded yeeb nkab (LSAW), thiab kauv welded yeeb nkab.
Hauv kev tsim hluav taws xob, "SC" yog siv los qhia tias nws tuaj yeem siv los ua cov yeeb nkab dej los yog cov yeeb nkab threading, uas yog tuab heev.
2. Cov kab yeeb nkab kuj yog cov yeeb nkab xaim, uas yog nyias nyias, sawv cev los ntawm "T", thiab tsuas yog siv tau rau cov yeeb nkab threading. 3. ERW yeeb nkab yog "siab-frequency resistance welded yeeb nkab", uas txawv ntawm cov txheej txheem vuam ntawm cov yeeb nkab zoo tib yam, thiab cov vuam yog ua los ntawm melting lub hauv paus hlau nrog lub cev, thiab cov neeg kho tshuab lub zog zoo dua li ntawm General welded yeeb nkab.
ERW sawv ntsug rau kev siv vuam, uas muaj cov yam ntxwv ntawm kev ua haujlwm siab, tus nqi qis, cov khoom txuag, thiab yooj yim automation, yog li nws tau siv dav hauv ntau yam kev lag luam xws li aviation, aerospace, lub zog, hluav taws xob, tsheb, thiab kev lag luam teeb, thiab yog ib qho ntawm cov txheej txheem vuam tseem ceeb.
