Awọn alagbara, irin elekiturodu lilo akiyesi

1. chromium alagbara, irin ni o ni awọn ipata resistance (oxidizing acid, Organic acid, cavitation) , ooru resistance ati wọ resistance.Nigbagbogbo a lo ninu awọn ohun elo agbara, kemikali, epo ati awọn ohun elo ẹrọ miiran.Chromium alagbara, irin ko dara weldability, yẹ ki o san ifojusi si awọn alurinmorin ilana, ooru itọju ipo ati awọn asayan ti yẹ elekiturodu.

2. CR-13 irin alagbara, irin ni o ni ti o ga líle lẹhin alurinmorin ati ki o jẹ rorun lati gbe awọn kiraki.Ti o ba ti kanna iru ti chromium alagbara, irin elekiturodu (G202, G207) ti lo fun alurinmorin, o gbọdọ wa ni preheated loke 300 ° C ati ki o tutu nipa 700 ° C lẹhin alurinmorin.Ti o ba ti alurinmorin ko le wa ni ti gbe jade ranse si-weld ooru itọju, ki o si awọn wun ti chromium-nickel alagbara, irin elekiturodu (A107, A207) .

3. Chromium 17 irin alagbara, lati le mu ilọsiwaju ibajẹ ati weldability dara si ati ki o mu iye ti o yẹ fun awọn eroja iduroṣinṣin gẹgẹbi Ti, Nb, Mo, ati bẹbẹ lọ, weldability dara ju chromium 13 irin alagbara irin.Nigbati iru kanna ti chromium alagbara, irin elekiturodu (G302, G307) ti lo, o yẹ ki o wa ni preheated loke 200 ° C ati tempered ni ayika 800 ° C lẹhin alurinmorin.Ti alurinmorin ko ba le ṣe itọju ooru, lẹhinna yiyan ti chromium-nickel alagbara, irin elekiturodu (A107, A207) .CR-NI alagbara, irin elekiturodu ni o ni ti o dara ipata resistance ati ifoyina resistance, o gbajumo ni lilo ninu kemikali ise, ajile, Epo ilẹ, egbogi ẹrọ ẹrọ.

4. 0 ati ni isalẹ le ṣee lo fun gbogbo-ipo alurinmorin.

6. Chromium-nickel alagbara, irin ti a bo ni o ni titanium-calcium iru ati kekere hydrogen iru.Calcium titanate iru le ṣee lo ni AC ati DC, ṣugbọn awọn ilaluja ti aijinile AC alurinmorin, nigba ti o rọrun lati pupa, ki bi lati lo DC ipese agbara.Iwọn opin

 

7. Awọn elekiturodu yẹ ki o wa ni gbẹ, iru titanium-calcium yẹ ki o gbẹ ni 150 ° C fun wakati 1, ati pe iru hydrogen kekere yẹ ki o gbẹ ni 200 ° C si 250 ° C fun wakati 1 (ko si gbigbẹ tun, bibẹẹkọ. awọn ti a bo jẹ rorun lati kiraki ati Peeli pa) , se awọn elekiturodu ti a bo epo duro epo ati awọn miiran idoti, ki bi ko lati mu awọn erogba akoonu ti awọn weld ati ki o ni ipa awọn didara ti awọn alurinmorin.

8. Ni ibere lati se awọn ipata laarin awọn oju ṣẹlẹ nipasẹ alapapo, awọn alurinmorin lọwọlọwọ ko yẹ ki o tobi ju, kere ju erogba irin elekiturodu nipa 20% , ARC yẹ ki o ko ni le gun ju, awọn ọna itutu laarin awọn fẹlẹfẹlẹ, lati dín ilẹkẹ jẹ yẹ. .
