ERW (hluav taws xob tiv taus vuam) cov kav dej muaj cov kev cuam tshuam hauv qab no thaum tau siv dav, uas cuam tshuam nrog lawv qhov kev ua tau zoo thiab kev nyab xeeb ntawm kev siv:
Kev pheej hmoo siab ntawm Weld Tsis Txaus Siab
- Cov yam tsis xws luag xws li tsis muaj fusion thiab txias vand
- Cov tsis xws luag tuaj yeem ua rau qhov tsis txaus siab faib ntawm cov kav dej ntws, txo lub zog, thiab muaj feem cuam tshuam kom tawg, tshwj xeeb yog nyob hauv ib puag ncig siab.
- Tsis txaus teb cov lus tawm thaum tshav kub kub los yog cov ntug tsis zoo ntawm cov kab txaij yog lub qhov tseem ceeb ntawm cov hlau oxide tsim cov hluav taws kub ua rau muaj cov fusion zoo.
Txwv corrosion tsis kam
- Lub cheeb tsam weld yog kev ntxim rau kev kho mob corrosion thiab yuav tsum muaj kev kho xeb ntxiv. Nws yog ntau dua li nquag mus rau corrosion hauv zos ua tsis tiav dua li cov kav dej seamless.
- Corrosion khoom (xws li manganese oxide thiab silicon dioxide) accidulate nyob rau hauv qhov chaw txias vuam, uas accelerates cov khoom siv kom ceev.
Limited SIV
- Not suitable for high pressure (>10MPa), high temperature (>300 degree) lossis cyclic load. Muaj qhov xwm txheej ntawm kev tawg ntawm girth wels hauv roj thiab roj thauj khoom, thiab muaj feem cuam tshuam nrog cov txheej txheem vuam tsis raug, misalignment thiab lwm yam.
- Nruj me ntsis kev tswj hwm
- Kev tswj hwm cov vuam zoo tshaj plaws yog tsim nyog los tswj qhov kub thiab txias (ua yuam kev ±) degree), extrusion ntim (phab ntsa tuab 5% ± 0.5mm) thiab qhib lub kaum sab xis
- Impurities los yog burrs ntawm ntug ntawm lub phaj tuaj yeem ua rau cov zog luv luv thiab txias vuam tsis zoo, uas yuav tsum muaj dej siab / Ultrasonic kuaj.
