Kotahi noa te paparanga, ka taea e koe te whakatutuki i te aukati waikura o te riipene weld

Ka whakamahia te pourewa mo te whakamaarama, te pure, te whakauru, te whakamaarama me etahi atu taputapu matū, ko te nuinga o nga taputapu pourewa me whakapiri atu ki te waikawa, te alkali, te tote, te whakarewa pararopi me etahi atu purongo kino, na reira he mea tika ki te whakairi i tetahi waahanga nui o te paparanga aukati. i roto i te porotaka me nga wahanga hiri.Hei huarahi pai mo te whakarewanga o te mata, ka whakamahia nuitia te papa tihorea i roto i te whakahiato i nga pourewa o nga taputapu matū.
Ko te hangarau paparanga hiko tuku iho he paparua-rua te hangarau o te papa pewa kua rukuhia me te paparanga whakawhiti me te paparanga aukati waikura, engari he roa te huringa hangahanga o tenei hangarau me te utu hangahanga nui.Hei whakaoti i tenei raruraru, kua whakawhanakehia e JingQunCo nga taonga whakarewa paparanga kotahi (GDS-309LA welding strip, GXS-ED308L electroslag flux), ka taea te whakatutuki i te painga o te paparua-rua me te paparanga kotahi anake, ka taea te ngawari. te tukanga whakapapa mai i te paparanga rua ki te paparanga kotahi.

Te matotoru o te weld pass: tata ki te 4.7mm

Whānui paiherea: āhua 62.5mm

Te ahua o te weld pass: he ataahua te ahua, he papatahi te mata o te weld, he maeneene te whakawhiti o te huha.
