490Mpa Tes Electrode Rau Cov Hlau Hlau
Daim ntawv thov & Standard & Ceeb toom:
1. Haum rau welding ntawm CARBON STEEL thiab qis ALLOY STEEL, zoo li lub zog sib xws ntawm BOILER, pipeline, tsheb, Lub tsev, BRIDGE thiab lwm yam qauv, xws li Q345.
2. Tus qauv peb ntsib: GB/T5117 E501, AWS A5.1 E701 & A5.1M E491, ISO2560-A:E 42 3 B 2 2, ISO 2560-B: E4915 A
Cov ntsiab lus rau kev mloog:
1. Ua ntej vuam, cov electrode yuav tsum tau ci ntawm 350 ℃ rau 1 teev thiab coj raws li xav tau.
2. Ua ntej welding, lub vuam yuav tsum tau ntxuav ntawm xeb, roj, dej thiab lwm yam impurities.
3. Vuam yuav tsum tau ua nrog luv arc, nqaim hla vuam yog tsim nyog. "
Nta
1. Tsawg hydrogen potassium electrode, ruaj khov arc, zoo nkauj tsim, exquisite, me ntsis txaws, yooj yim de-slagging, zoo tawv nqaij tiv taus, zoo porosity kuj.
2. rooj mechanical zog, zoo plasticity, cuam tshuam toughness thiab tawg kuj.
GEL-57 qis carbon steel tes electrode, qib thoob ntiaj teb yog E7015, Tuam Tshoj qib yog J507, belongs rau qis hydrogen sodium alkaline electrode, haum rau vuam Q345 qib zog ntawm cov hlau tsis tshua muaj hlau. J yog thawj tsab ntawv ntawm structural steel hlws ris, uas stands rau structural steel electrode. Lub zog tensile ntawm 50 fused hlau yog sib npaug los yog ntau dua 490MPa (50 KGF / mm2). Tsawg sodium hydrogen electrode. Cov electrode yog nyob rau hauv txoj kab nrog tus qauv E5015, qhov twg E sawv cev rau cov electrode nrog lub zog tensile ntawm 50 fused hlau sib npaug los yog ntau dua 490MPa (50 KGF / mm2). 1 qhia tag nrho txoj hauj lwm vuam electrode (pav vuam, ntsug vuam, kab rov tav vuam, ntsug vuam). Tsawg sodium hydrogen electrode. Cov electrode tsis muaj arc stabilizer thiab tsuas yog siv tau rau DC thim rov qab polarity vuam.
