Vuam Txoj Kev Qhia rau 235 Carbon Steel Phaj
Cov txheej txheem vuam tsim nyog
Cov tswv yim pom zoo suav nrog SMAW (stick welding), GMAW/MIG, thiab TIG vuam.
Siv cov ntaub ntawv sib xyaw ua ke kom ntseeg tau tias muaj zog, tsis xws luag -cov pob qij txha dawb.
Pre-Weld thiab Interpass Control
Siv preheating (piv txwv li, 80-120 degree) rau cov phaj tuab lossis qhov chaw txias kom tsis txhob tawg.
Tswj qhov kub thiab txias ntawm cov khoom siv hluav taws xob los tswj cov cua sov- thaj tsam cuam tshuam thiab txo qis kev cuam tshuam.
Kev txiav txim siab tom qab Weld
Cia maj mam txias kom tsis txhob muaj kev ntxhov siab lossis tawg.
Tshawb xyuas welds rau qhov tsis xws luag xws li porosity lossis undercut thiab ua kev ntxhov siab -kev kho mob yog tias xav tau.
