Whakaahuatanga: Ko te R107 he pearlitic wera-aukati maitai electrode ki te iti-waiwai konutai paninga kei roto 0.5% Mo. Whakamahia DCEP (tika hiko o nāianei pai) a taea paiherea i roto i positions.The weldment me preheated ki 90 ~ 110 ℃ i mua i fehokotaki'anga .

Taupānga: Kei te whakamahia te reira mo te fehokotaki'anga putorino kōhua ​​ki te pāmahana mahi i raro i 510 ° C (pērā i 15Mo, me ētahi atu), a ka taea hoki te whakamahi mo te fehokotaki'anga whānui iti-kokohanga maitai teitei-kaha.

Panui:

1. Me tunuhia te electrode mo te 1 haora i te 350 ℃ i mua i te mahi whakapiri;

2. He mea nui ki te horoi i te waikura, te unahi hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.
