I-electrode yokushisela i-hydrogen ephansi ye-E7018-1H4 Isithombe Esivelele
  • I-electrode yokushisela ye-hydrogen ephansi ye-E7018-1H4

I-electrode yokushisela ye-hydrogen ephansi ye-E7018-1H4

Incazelo emfushane:

I-electrode yohlobo lwe-iron-powder ephansi ye-hydrogen yokushisela yonke indawo yensimbi eqine kakhulu yebanga elingu-490N/mm2.


Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

I-AWS A5.1 E7018-1 H4
I-EN ISO 2560-AE 46 4 B 12 H5
I-JIS Z 3211 E4918-1 H5
Izici kanye Nokusetshenziswa
I-AWS A5.1 E7018-1 H4 Izinduku zokushisela, i-electrode yokushisela iyi-electrode yohlobo lwe-hydrogen ephansi yensimbi-impuphu yokushisela yonke indawo yensimbi eqine kakhulu engu-490N/mm2. Yenzelwe ukusetshenziswa kwe-pass eyodwa neningi. Umkhiqizo ukhanga kahle i-welder futhi ukhiqiza i-arc ezinzile ekhiqiza i-sphatter ephansi. Ukhiqiza izinsimbi zokushisela ezinezakhiwo ezinhle kakhulu zemishini kanye nokuqina komthelela ekushiseni okuphansi (-45℃) kanye ne-hydrogen esakazeka kancane. Izici zawo zenza umkhiqizo ufanelekele izinsimbi ze-alloy eziphansi, izinsimbi ze-carbon ephakathi, amapuleti ensimbi esindayo, izinsimbi ezibunjiwe, insimbi ye-LPG ebulewe nge-aluminium futhi ikakhulukazi ukushisela izinsimbi ezinokushisela okuphansi.

Amanothi ngokusetshenziswa:
1. Ngaphandle kokuthi isimo sokugcina sivikelekile futhi ukupakisha kungonakali, sincoma kakhulu ukuthi womise ama-electrode ku-350-400℃ amahora angu-1-2 ngaphambi kokusebenzisa.
2. Sebenzisa indlela yesinyathelo esingemuva ukuvimbela ukubhoboza kwe-arc ukuqala.
3. Ukugcina ubude be-arc bufushane kunconywa kakhulu ukuvimbela ukuqoqwa komswakama.
