VIII. Cov Lus Nquag Nug (FAQ)

Q1: Vim li cas thiaj tsis siv hluav taws xob rau E7018-H4R?

A1: Tsawg {{{- hydrogen txheej txheem muaj hluav taws xob tsis zoo, thiab ACC ua haujlwm tsis txaus ntseeg (arc breakage, ntau dhau lawm). DC Rov qab polarity tuaj yeem muab ib qho ruaj khov arc, ua kom muaj kev sib sau ua ke ntawm Weld pas dej thiab txo qhov tsis xws luag.

Q2: Yuav ntau lub voj voog kom qhuav cuam tshuam rau hluav taws xob kev ua tau zoo?

A2: Qhov ntau kawg ntawm 3 lub voj voog kom qhuav (350℃/ 1 teev) raug tso cai. Tshaj dhau qhov kev txwv no yuav ua rau muaj kev cuam tshuam ntawm cov khoom siv hauv cov txheej txheej thiab txo cov nplaum ntawm cov txheej thiab cov thawj coj, ua kom cov khoom sib txuas thiab porosity. Nws raug nquahu kom tsis txhob siv cov electrodes tom qab ntau dua 3 lub tshuab ziab khaub ncaws.

Q3: Puas yog nws tov nrog acidic electrodes zoo li E6013 rau Weld tib tus qauv?

A3: Tsis pom zoo. E6013 muaj cov ntsiab lus hydrogen ntau (nquag mus tawg), thiab nws lub zog tensile (txog 414Mpa) yog qis dua li ntawm E7018-H4R (483MPA). Kev sib xyaw yuav ua rau sib koom ua ke tsis sib xws thiab nce kev pheej hmoo ntawm kev tawg.

Q4: Dab tsi ua rau porosity ntawm weld nto?

A4: Common causes include: insufficient electrode drying (excessive hydrogen content after moisture absorption), environmental humidity >80%, cov roj tsis huv / xeb ntawm cov khoom siv hauv paus, thiab ntau tam sim no ua rau lub pas dej weld.
