AWS E9015-D1
Whakaahuatanga: Ko te J607 he hiko hiko teitei teitei me te paninga konutai iti-hydrogen.Whakamahia te DCEP (te hiko hiko tika o naianei), ka taea te paihere ki nga waahi katoa.
Taupānga: Whakamahia mō te fehokotaki'anga waro maitai waro me te iti-konumohe tiketike-kaha hanganga maitai o te kaha hāngai, pērā i Q420, etc.

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;
3. Whakamahia te mahi arc poto ina whakapiri.He tika te ara fehokotaki'anga kuiti.
