Nickel et Nickel Alloy Welding Electrode
Ni307-3
GB/T ENi6182
AWS A5.11 ENiCrFe-3
Descriptio: Ni307-3 est anickel-based electrode cum low-hydrogen sodium membrana dignitatis.Utere DCEP (electrode current directum positivum).Repugnantiae rimae bonam habet, quia in manganeso, niobium, et aliis elementis commixtis quodammodo continet.
Applicationem: Ponitur pro glutinonickel-chromium-admixtiones ferri (ut UNS N06600) et superficies ferri.Temperatura operaria plerumque non altior quam 480 ° C est, et rima resistentia est bona.Apta fornax atomica pressionis vasis et cisternina glutino chemico.

Commendatur current:
| Rod diam mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding current A） | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Animadverte:
1. Electrodum coquendum est hora 1 circiter 300℃ ante operationem glutinum;
2. Essentiale est purgare ferruginem, oleum, aquam, et immunditias in partibus glutino ante glutino.Conare brevi arcum pactionem utere.
