Akiyesi:
Àwọn ìṣọ́ra:
1. Awọn elekiturodu gbọdọ wa ni ndin ni nipa 300 ° C fun 1 to 2 wakati ṣaaju ki o to alurinmorin;
2. Ọrinrin, epo, oxides ati awọn impurities miiran lori dada ti weldment gbọdọ wa ni kuro ṣaaju ki o to alurinmorin.
3. Nigbati alurinmorin ohun alumọni idẹ tabi surfacing alurinmorin lori irin, ko si preheating wa ni ti beere.Iwọn otutu ti o ṣaju fun alurinmorin bàbà funfun jẹ nipa 450 ° C, ati iwọn otutu ti o ṣaju fun idẹ alurinmorin jẹ nipa 300 ° C;
4. Kukuru-aaki alurinmorin yẹ ki o wa lo nigba alurinmorin.Lakoko alurinmorin olona-Layer, slag laarin awọn fẹlẹfẹlẹ gbọdọ jẹ
patapata kuro;lẹhin alurinmorin, lu awọn weld pẹlu kan alapin ori ju lati liti awọn oka, imukuro wahala, ki o si mu awọn agbara ati ṣiṣu ti awọn weld.
