Nqe lus piav qhia: J555 yog ib qho ntsug downward electrode nrog siab cellulose potassium txheej.AC thiab DC dual-lub hom phiaj.Thaum welding downward, molten hlau thiab slag yuav tsis ntws.Nws muaj zog arc zoo heev thiab nkag mus.Hauv qab vuam tuaj yeem tsim ntawm ob sab thiab muaj vuam ceev.
Daim ntawv thov: Siv rau vuam qis alloy steel kav.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
C | Mn | Si | S | P |
≤ 0.20 | ≥1.00 Nws | ≤0.50 | ≤ 0.035 | ≤ 0.035 |
Mechanical zog ntawm weld hlau:
Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % | Tus nqi cuam tshuam (J) -30 ℃ |
lav | ≥540 | ≥440 | ≥17 | ≥ 27 |
X-ray kuaj: qib II
Pom zoo tam sim no:
(mm) Qws txoj kab uas hla | 2.5 | 3.2 | 4.0 | 5.0 |
(A) Vuam tam sim no | 45 ~ 75 ib | 80 ~ 120 | 130-160 ib | 170-190 ib |
Daim ntawv ceeb toom:
Cov electrode yuav tsum tau ci ntawm 70-90 ° C rau 1 teev ua ntej siv.Qhov kub yuav tsum tsis txhob siab dhau, txwv tsis pub cov cellulose hauv txheej yuav puas.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim nyob rau xyoo 2000. Peb tau koom nrog kev tsim khoom ntawmvuam electrodes, vuam rods, thiab vuam consumables rau ntau tshaj 20 xyoo.
