Incazelo: I-J506NiMA ne-J507NiMA ama-electrode ensimbi abamba umswakama we-ultra-low hydrogen-coated low-alloy steel.Insimbi ediphozithi ine-plasticity enhle kakhulu, izinga lokushisa eliphansi eliqinile kanye nokumelana nokuqhekeka, futhi ingashiselwa kuzo zonke izikhundla.I-coating imelana nokumuncwa komswakama.Ngemuva kokuthi i-electrode ibhakwe ku-400 ° C x 1h futhi ipakwe endaweni enomswakama ohlobene ≥ 80% amahora angu-4, okuqukethwe komswakama kokumboza kusahlangabezana nezidingo zokusetshenziswa.

Isicelo: Isetshenziselwa ukushisela amapulatifomu kawoyela, imikhumbi, imikhumbi yokucindezela, nezinye izakhiwo ezenziwecarbon steel kanye nensimbi ephansi ye-alloy.

Ukwakheka kwamakhemikhali ensimbi ye-weld(%):

Izici zemishini ye-weld metal:

Okuqukethwe kwe-hydrogen yokusabalalisa kwensimbi efakiwe: ≤5.0mL/100g (i-gas chromatography noma indlela ye-mercury)

Okuqukethwe okunomswakama kwezingubo ze-electrode: ≤0.30%

Ukuhlolwa kwe-X-ray: I grade

Okwamanje okunconyiwe:

Isaziso:

1. I-electrode kufanele ibhakwe ihora elingu-1 ku-350 ~ 400 ℃ ngaphambi kokusebenza kokushisela;

2. Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela;

3. Sebenzisa ukusebenza kwe-arc emfushane lapho ushisela.Ithrekhi yokushisela emincane ilungile.
