I-Low Alloy Steel Welding Rod AWS E8018-G (J556Fe) Manual Metal Arc Electrodes

I-Electrode yeWelding yentsimbi ephantsi ye-Alloy

J556Fe                                              

GB/T E5518-G

I-AWS E8018-G 

Inkcazo: I-J556fe yi-electrode yentsimbi e-alloy ephantsi enomgubo wesinyithi kunye nophahla oluphantsi lwe-hydrogen. Zombini i-AC kunye ne-DC zingasetyenziswa, kwaye zinokudityaniswa kuzo zonke iindawo.

Isicelo: Isetyenziselwa ukuwelda intsimbi ye-carbon ephakathi kunye nezakhiwo zentsimbi ye-alloy ephantsi ezifana ne-Q390.

Ukwakheka kweekhemikhali zesinyithi esijiyiweyo (%):

Iimpawu zoomatshini zesinyithi esijijekileyo:

Umthamo we-hydrogen osasazekileyo kwisinyithi esigciniweyo: ≤10.0mL/100g (indlela ye-mercury okanye i-gas chromatography)

Ukuhlolwa kwe-X-ray: Ibanga loku-1

I-current ecetyiswayo:

Isaziso:

1. I-electrode mayibhakwe iyure e-1 kwi-350℃ ngaphambi kokuba isebenze nge-welding;

2. Kubalulekile ukucoca umhlwa, isikali seoyile, amanzi, kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba kuweldwe;

3. Sebenzisa i-arc operation emfutshane xa udibanisa. Indlela yokuncamathela ebhityileyo ifanelekile.
