Ubushushu obuphantsi be-Steel Welding Electrode
W707
GB/T E5015-G
AWS A5.5 E7015-G
Inkcazo: I-W707 i-electrode yensimbi ephantsi yobushushu kunye ne-low-hydrogen sodium coating.Sebenzisa i-DCEP (i-electrode echanekileyo yangoku) kwaye inokudityaniswa kuzo zonke izikhundla.Isinyithi esidipozithiweyo sisenempembelelo entle yokuqina kwi -70°C.
Isicelo: Isetyenziselwa ukuwelda intsimbi yobushushu obuphantsi njenge-2.5Ni.
Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):
C | Mn | Si | Ni | S | P |
≤0.08 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Iimpawu zobuchwephesha bentsimbi ye-weld:
Into yovavanyo | Tensile strength Mpa | Unikeze Amandla Mpa | Elongation % | Ixabiso lempembelelo (J) -70℃ |
Iqinisekisiwe | ≥490 | ≥390 | ≥22 | ≥27 |
Umxholo we-hydrogen we-Diffusion yensimbi egciniweyo: ≤6.0mL / 100g (indlela ye-glycerin) okanye ≤10mL / 100g (i-mercury okanye indlela ye-chromatography yegesi)
Ukuhlolwa kwe-X-reyi: I grade
yangoku eCetyisiweyo:
(mm) Intonga yobubanzi | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
(A) I-Welding yangoku | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Isaziso:
1. I-electrode kufuneka ibhakwe ngeyure eli-1 kwi-350 ℃ ngaphambi kokusebenza kwe-welding;
2. Zama ukusebenzisa amandla omgca omncinci xa udibanisa, i-multi-layer kunye ne-multi-pass welding.
