Apejuwe: Eyi jẹ iṣuu soda hydrogen kekere ti a bo elekiturodu pataki fun irin alumini.Lo DCEP (taara ti isiyi elekiturodu rere), ati ki o le ti wa ni welded ni gbogbo awọn ipo pẹlu kukuru aaki isẹ.J557SLA le ti wa ni welded taara lai yọ awọn aluminized Layer lori yara dada ṣaaju ki o to alurinmorin.Ṣugbọn J557SLB yẹ ki o yọ aluminized Layer lori yara dada ṣaaju ki o to alurinmorin.

Ohun elo: O ti wa ni lilo fun alurinmorin awọn aluminiomu irin be labẹ awọn ipata alabọde ti hydrogen sulfide, sulfur, amonia, ammonium bicarbonate ati hydrogen nitrogen pẹlu ṣiṣẹ otutu ni isalẹ 540 ° C.Bii awọn paipu igbomikana, ohun elo isọdọtun epo, ohun elo ajile ati awọn paipu nya si, ati bẹbẹ lọ.

 Apapọ kemikali ti irin weld (%):

 Awọn ohun-ini ẹrọ ti irin weld:

Akoonu hydrogen tan kaakiri ti irin ti a fi silẹ: ≤6.0mL/100g (ọna glycerin)
