Iti Alloy Steel Welding Hiko
J556Fe
GB/T E5518-G
AWS E8018-G
Whakaahuatanga: Ko te J556fe he hiko rino koranu iti me te paura rino me te paninga hauwai iti.Ka taea te whakamahi i te AC me te DC, ka taea te paihere ki nga waahi katoa.
Taupānga: Whakamahia mō te fehokotaki'anga waro maitai me iti hanganga koranu maitai pērā i Q390.
Te hanganga matū o te whakarewa whakarewa(%):

Panui:
1. Me tunuhia te electrode mo te 1 haora i te 350 ℃ i mua i te mahi whakapiri;
2. He mea nui ki te horoi i te waikura, te unahi hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri;
3. Whakamahia te mahi arc poto ina whakapiri.He tika te ara fehokotaki'anga kuiti.
