Inkcazo: Le yi-electrode ekhethekileyo ene-hydrogen sodium ephantsi egqunywe yintsimbi ye-aluminium. Sebenzisa i-DCEP (i-electrode yangoku echanekileyo), kwaye ingadityaniswa kuzo zonke iindawo nge-arc operation emfutshane. I-J557SLA ingadityaniswa ngokuthe ngqo ngaphandle kokususa umaleko we-aluminium kumphezulu we-groove ngaphambi kokudityaniswa. Kodwa i-J557SLB kufuneka isuse umaleko we-aluminium kumphezulu we-groove ngaphambi kokudityaniswa.

Ukusetyenziswa: Isetyenziselwa ukuwelda isakhiwo sentsimbi esenziwe nge-aluminium phantsi kwe-hydrogen sulfide, i-sulfur, i-ammonia, i-ammonium bicarbonate kunye ne-hydrogen nitrogen enobushushu obuphantsi kwama-540°C. Ezifana nemibhobho yebhoyila, izixhobo zokucoca ipetroliyam, izixhobo zesichumiso kunye nemibhobho yomphunga, njl.njl.

 Ukwakheka kweekhemikhali zesinyithi esijiyiweyo (%):

 Iimpawu zoomatshini zesinyithi esijijekileyo:

Umthamo we-hydrogen osasazekileyo kwisinyithi esigciniweyo: ≤6.0mL/100g (indlela ye-glycerin)

Ukuhlolwa kwe-X-ray: Ibanga loku-1

I-current ecetyiswayo:

Isaziso:

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

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