JIS G3454 ERW yeeb nkab hlau stamping kev pabcuam yog ib qho tseem ceeb ntawm ERW yeeb nkab hlau tsim thiab tsim khoom. JIS G3454 yog Japanese Industrial Standard uas teev cov yeeb nkab hlau carbon rau kev pabcuam kub siab. ERW (hluav taws xob tsis kam welded) yeeb nkab hlau yog tsim los ntawm cov txheej txheem uas cov npoo ntawm cov ntawv hlau lossis cov strips raug cua sov thiab sib xyaw ua ke hauv qab siab, tsim cov yeeb nkab seamless thiab muaj zog. Cov kev pabcuam stamping koom nrog hauv kev tsim cov JIS G3454 ERW Yeeb Nkab Hlau ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo thiab kev ntseeg siab ntawm cov yeeb nkab no. Cov kev pabcuam stamping cuam tshuam nrog kev siv cov tshuab siab siab los tsim cov yeeb nkab rau qhov ntev thiab cov lus qhia xav tau. Cov txheej txheem no ua kom ntseeg tau tias cov yeeb nkab muaj qhov kawg du thiab meej, thiab phab ntsa tuab sib xws thoob plaws nws qhov ntev. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm JIS G3454 ERW yeeb nkab hlau xovxwm kev pabcuam yog lub peev xwm los tsim cov yeeb nkab nrog qhov tseeb zoo heev thiab kev sib txuas ua ke. Cov kev pabcuam stamping tso cai rau kev tswj hwm nruj dua ntawm cov txheej txheem tsim khoom, ua kom ntseeg tau tias cov yeeb nkab ua tau raws li cov qauv thiab cov lus qhia xav tau. Tsis tas li ntawd xwb, kev siv cov tshuab siab thaum lub sijhawm ua cov kev pabcuam stamping pab tsim cov kav dej uas muaj zog thiab ruaj khov, ua rau lawv haum rau ntau yam kev siv hauv kev lag luam xws li roj thiab roj av, kev tsim kho, thiab tsheb. Tsis tas li ntawd xwb, JIS G3454 ERW cov yeeb nkab steel nias kuj tseem tuaj yeem tsim cov kav dej du thiab zoo nkauj. Cov tshuab siv hauv cov kev pabcuam stamping tuaj yeem txhuam thiab ua kom zoo nkauj ntawm cov yeeb nkab, ua rau cov khoom pom tseeb dua. Qhov no tseem ceeb heev rau cov ntawv thov uas cov yeeb nkab raug nthuav tawm lossis pom vim nws txhim kho qhov tsos tag nrho thiab ua kom tiav zoo. Hauv kev xaus, JIS G3454 ERW Cov Yeeb Nkab Hlau nias cov kev pabcuam yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom, ua kom ntseeg tau tias cov yeeb nkab zoo thiab txhim khu kev qha rau ntau yam kev siv siab. Nws ua kom paub tseeb tias qhov tseeb ntawm qhov ntev, kev sib txuas zoo, thiab cov nplaim du, ua rau cov kav dej no haum rau ntau yam kev lag luam thiab kev siv.
