Steel nto txheej yog tsim los rau corrosion los yog hniav, los yog ob qho tib si.Lub seam vuam, tsis tsuas yog kom tau txais kev sib koom ua ke txaus, tab sis kuj yuav tsum tau ua kom muaj kev ua haujlwm ntawm txheej txheej.Los ntawm cov kev xav tau ntawm lub zog, cov txheej txheem vuam seam thiab cov hlau tsis muaj coated zoo sib xws, suav nrog cov txheej txheem kev xav tau ntawm cov txheej txheem vuam, cov txheej txheem vuam yuav tsum hloov kho qhov tsim nyog, tom qab ntawd xyuam xim rau qhov cuam tshuam ntawm kev tiv thaiv txheej, tso cai rau electrode indentation, txheej thiab niam ntoo thiab hlau alloys nyiam tsim adhesions tshwm sim nrog electrodes.

Galvanized steel yeeb nkabyog ua kom cov corrosion kuj ntawm steel, tab sis tom qab galvanized me me steel yog nyuaj dua tsis galvanized steel phaj vuam.Feem ntau yog vim qhov qis melting point ntawm zinc txheej (kwv yees li 419C), thaum lub sij hawm vuam galvanized txheej yog thawj melted thiab cov tub ntxhais cov tswv cuab thiab cov vuam electrode thiab cov vuam cov tswv cuab thiab cov kev sib cuag nto ntawm vuam tam sim no cov tswv cuab, qhov chaw sib cuag tau nce. , qhov ceev tam sim no txo ​​qis thiab kev sib ze ntawm electrode thiab weldrode firvanized looj ooyoy (cuzn), nws cov hluav taws xob condoying, thermal kev ua haujlwm tsis zoo.Lub boiling point ntawm zinc 906C, thaum kub tshaj qhov kub no, lub evaporation ntawm zinc.Qhov tsim ntawm pores los yog tawg nyob rau hauv lub nugget, lub tshav kub cuam tshuam cheeb tsam yog diffused rau hauv lub connector ua rau embrittlement tawg tej zaum yuav nyob rau hauv siab.Kev ntsuam xyuas tau pom tias qhov me me ntawm qhov nkag mus (10 - 26%), tsawg dua qhov tawg;welding ceev yog siab, qhov txias txias tsis zoo, kub nto thiab qhov tob tob, yog ib qho yooj yim rau tawg.Yog li ntawd, txhawm rau txhawm rau txhawm rau txoj kab uas hla thiab qhov sib koom ua ke muaj zog, yuav tsum tau sim siv cov tam sim no me me, vuam ceev thiab lub zog sab nraud.Electrodes yuav tsum tau siv rau embossing rau cov menyuam nruas tsav, thiaj li yuav ua kom lub raj puag ncig trim thiab ntxuav lub nto electrode loj.
