Whakaahuatanga: Ko te T207 he irahiko koranu parahi me te matua parahi silicon me te paninga konutai hauwai iti.Whakamahia te DCEP (te hiko tika o naianei) me nga ahuatanga miihini nui.He pai te waikura ki nga waikawa pararopi atu i te waikawa nitric, te nuinga o nga waikawa waro me te wai moana.

 

Taupānga: He pai mo te whakapiri i te parahi, te parahi silicon me te parahi, te whakarewa i te papa o nga raina o nga pipeline miihini matū, etc.

Panui:

Whakatupato:

1. Me tunuhia te electrode ki te 300°C mo te 1 ki te 2 haora i mua i te whakapiri;

2. Ko te makuku, te hinu, te waikura me etahi atu poke i runga i te mata o te weldment me tango i mua i te whakapiri.

3. A, no te fehokotaki'anga silicon parahi fehokotaki'anga mata ranei i runga maitai, kahore preheating te hiahiatia.Ko te pāmahana preheating mō te fehokotaki'anga parahi parakore ko e pā ana ki 450°C, me te pāmahana preheating mo te parahi fehokotaki'anga ko e pā ana ki 300°C;

4. Me whakamahi te whakapiri poto-arc i te wa o te whakapiri.I te wa o te whakapiringa maha-papa, me noho te para i waenga i nga paparanga

tino tangohia;i muri i te whakapiri, hama te weld ki te hama mahunga papatahi ki te whakamahine i te witi, whakakore ahotea, me te whakapai ake i te kaha me te kirihou o te weld.
