Inkcazo: Le yi-sodium ye-hydrogen ephantsi egqunywe i-electrode ekhethekileyo yentsimbi edibeneyo.Sebenzisa i-DCEP (i-electrode yangoku echanekileyo), kwaye inokudityaniswa kuzo zonke izikhundla kunye nokusebenza okufutshane kwe-arc.I-J557SLA inokudityaniswa ngokuthe ngqo ngaphandle kokususa umaleko we-aluminised kwi-groove surface phambi kwe-welding.Kodwa i-J557SLB kufuneka isuse umaleko we-aluminum kwindawo ye-groove ngaphambi kokuba i-welding.

Isicelo: Isetyenziselwa ukuwelda ulwakhiwo lwentsimbi olulunyunyisiweyo phantsi komgangatho wokutya wehydrogen sulfide, isulfure, ammonia, ammonium bicarbonate kunye nehydrogen nitrogen enobushushu obusebenzayo obungaphantsi kwama-540°C.Njengemibhobho yebhoyila, izixhobo zokucoca i-petroleum, izixhobo zesichumiso kunye nemibhobho yomphunga, njl.

 Ukwakhiwa kweekhemikhali zentsimbi edibeneyo(%):

 Iimpawu zobuchwephesha bentsimbi ye-weld:

Isiqulatho se-hydrogen ye-hydrogen yentsimbi egciniweyo: ≤6.0mL/100g (indlela ye-glycerin)

Ukuhlolwa kwe-X-reyi: I grade

yangoku eCetyisiweyo:

Isaziso:

1. I-electrode kufuneka ibhakwe ngeyure eli-1 malunga ne-350 ℃ ngaphambi kokusebenza kwe-welding;

2. Kubalulekile ukucoca umhlwa, isikali se-oyile, amanzi, kunye nokungcola kwiindawo zokuwelda phambi kokuba udibanise.
