J557SLA、J557SLB Rodhi Yekushongedza Yehydrogen Yakaderera AWS E8015-G Yakaderera Alloy Stick Electrodes eArc Welding

Electrode Yesimbi Yekushongedza Yesimbi Yakaderera

J557SLA、 J557SLB                                        

GB/T E5515-G

AWS E8015-G

Tsananguro: Iyi ielectrode yakakosha ine hydrogen sodium shoma yakafukidzwa nesimbi yakaruminika. Shandisa DCEP (electrode yakananga yemagetsi), uye inogona kusungirirwa munzvimbo dzese nekushanda kwenguva pfupi kwearc. J557SLA inogona kusungirirwa zvakananga pasina kubvisa layer yakaruminika pamusoro pe groove usati wabatanidza. Asi J557SLB inofanira kubvisa layer yakaruminika pamusoro pe groove usati wabatanidza.

Mashandisirwo: Inoshandiswa pakunamira chimiro chesimbi chakagadzirwa nealuminium pasi pehydrogen sulfide, sarufa, ammonia, ammonium bicarbonate uye hydrogen nitrogen ine tembiricha iri pasi pe540°C. Zvakadai semapaipi ebhoyira, michina yekuchenesa peturu, michina yefetereza nemapaipi emhepo, nezvimwewo.

 Kuumbwa kwemakemikari esimbi ye weld (%):

 Hunhu hwesimbi ye weld:

Kupararira kwehydrogen musimbi yakachengetwa: ≤6.0mL/100g (nzira yeglycerin)

Kuongororwa kweX-ray: Giredhi I

Inokurudzirwa yemagetsi:

Cherechedza:

1. Electrode inofanira kubikwa kweawa imwe chete pakupisa kwe350℃ isati yashandiswa pakunamira;

2. Zvakakosha kuchenesa ngura, mafuta, mvura, uye tsvina pazvikamu zvekunamira usati wanamira.
