Q: Cov teeb meem thiab kev daws teeb meem hauv SPCC stamping?
A: Teeb meem: Cracking, springback, wrinkling, khawb. Cov kev daws teeb meem: Cracking-Txhim kho lub kaum sab xis ntawm lub voj voog, txhim kho lubrication, siv S lossis A hom; Springback-Ntawm qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Wrinkling-Npaum lub zog tuav, ua kom zoo dua cov hlaws dai; Kos- Polish tuag, siv tshwj xeeb coated tuag, nce lubrication.
Q: Yuav ua li cas yog tias zinc txheej (yog tias tam sim no) tshem tawm / tawg thaum SPCC khoov?
A: Ua kom lub voj voog sab hauv ntawm curvature (≥ khoom thickness); siv cov dabtsi yog khoov- tiv taus txheej; re-zincify lossis tshuaj tsuag lub vojvoog tom qab khoov.
Q: Yuav ua li cas nrog kev sib tsoo ntau dhau thiab porosity thaum SPCC vuam?
A: Spot welding-Nruam tam sim no thiab siab; MIG/MAG-Siv qis- silicon vuam hlau, txo qhov voltage, nce roj ntws; TIG minimizes spatter; ntxuav thiab siv zinc- nplua nuj xim tom qab vuam.
Q: Yuav ua li cas los txhim kho qhov txo qis corrosion ntawm SPCC txiav npoo? A: Tom qab txiav, hla cov npoo, siv cov roj los tiv thaiv - xeb, lossis siv cov hmoov txheej los tiv thaiv lawv.
Q: Yuav ua li cas tshem tawm cov qoob loo toj siab hauv SPCC?
A: Siv tas li annealing thiab optimize tus txheej txheem; tswj qhov txias dov txo tus nqi thiab annealing kub kom txo tau lub zog tawm los rau hauv qab 230MPa.
