E7028 te hiko whakarewa

AWS A5.1 E7028 Rakau Whakarewas

Ko te hiko whakarewa AWS A5.1 E7028 he hiko maitai waro kua pania ki te paura hauwai-pāhare pākawa iti. Mā te paura rino i roto i te paninga ka piki ake te tere o te tāpae ki te 180%. He tino pai te whakamahinga, ā, ka taea te pupuri i te pewa pumau, te iti o te tauhiuhi, he ngāwari te tango i te paru, ā, ka taea te whakarewa i ngā tūranga katoa. He pai ngā āhuatanga miihini o te konganuku kua tāpae, ā, he tino pakari ki te pāmahana iti.

Tono

Ka whakamahia te AWS A5.1 E7028 ki te whakarewa papatahi me te whakarewa papatahi i roto i ngā hanganga i hangaia ki te maitai waro me te maitai koranu iti pērā i te maitai 16Mn, 09Mn2Si me A, B, D, E e whakamahia ana i roto i te hanga kaipuke.

Ngā Āhuatanga Hangarau o te Konukura Kua Whakatakotoria

Iahiko Tohutoro (DC)

Ngā Tuhipoka:

1. Me whakamahana te hikohiko i te pāmahana 350°C mō te 1 hāora. Whakamahanahia te tokotoko i ngā wā katoa e whakamahia ana.

2. Me horoi atu i te mea mahi ngā poke pēnei i te waikura, ngā paru hinu me te makuku.

3. E hiahiatia ana he pewa poto hei mahi whakarewa. He pai ake te ara whakarewa whaiti.

Te rokiroki me te tunu i te E7028 Welding Electrode

I te mea he iti te hauwai o te hikohiko E7016, metunu/ whakamarokei mua i te whakamahinga. Ko te pāmahana whakamaroke, tunu rānei e taunakitia ana mō te tokotoko E7028 e ai ki te AWS A5.1, Ripanga 1.3 he 500- 800°F (260- 425°C) mō te 1- 2 hāora.

Me pupuri te hiko kua tunua, kua maroke rānei i roto i te oumu pupuri kawe i te pāmahana 50-250°F (30-140°C) i te wā e whakamahia ana. Me whakahoki ngā hiko kāore i whakamahia ki ngā oumu pupuri tūmau.
