Nickel et Nickel Alloy Welding Electrode
Ni327-4
GB/T ENi6276
AWS A5.11 ENiCrMo-4
Descriptio: Ni327-4 est electrode nickel substructio cum sodium humili-hydrogenis efficiens.Usus DCEP (rectum current electrodeaffirmativus).Habet compositionem optimam glutino cum arcubus stabilibus combustionem, spatorem minus, scoriam removentem facilem;
et pulchram pugillo.Proprietates mechanicae metalli depositi sunt stabiles.
Applicatio: Usus ad glutino carbo-humili-chromi-molybdaeni admixtus, ut Hastelloy C276, ASTM B574, B575, B619, B622, B626, et etiam adhiberi potest ad glutino ferro dissimiles cum aliis nickel-admixtionibus substructis.

Commendatur current:
| Rod diam mm） | 2.5 | 3.2 | 4.0 |
| Welding current A） | 60 ~ 90 | 70~ 110 | 90~ 150 |
Animadverte:
1. Electrodum coquendum est hora 1 circiter circiter 300℃ ante operationem glutinum.Conare ut arcu brevi ad pugillo
2. Essentiale est purgare ferruginem, oleum, aquam, et immunditias in partibus glutino ante glutino.
3. Conare ad usum energiae parvae cum glutino, multi-strati et multi-passim glutino uti.
