He rite tonu te AWS E312-17 ki te 312-16, engari he nui ake te silica i roto i te paninga -17, ā, he iti iho te titanium-um, ka puta he pānga "Sprue-Arc" ina whakamahia ki ngā whakarewanga miro whakapae.

Whakaahuatanga me ngā Taupānga
He rite tonu te AWS E312-17 ki te 312-16, engari he nui ake te silica i roto i te paninga -17, ā, he iti iho te titanium, ka puta he pānga "Sprue-Arc" ina whakamahia ki ngā whakarewanga whakapae. Ka puta hoki he putunga whakarewa me te āhua ripple pai ake, he papatahi ake, he piko ake. He puhoi ake te hukapapa o te 312-17, ā, he pai ake te whakahaere ina whakamahia he tikanga tō. He kōwhiringa pai rawa atu mō ngā maitai uaua ki te whakarewa pērā i te maitai whakapakeke hau, ngā maitai waro waenga me te waro teitei. Ko te hikohiko tino pai hei whakamahi i te wāhi he kounga maitai kāore i te mōhiotia te konganuku turanga. He pai mō ngā tono rerekē maha e pā ana ki te maitai whakapakeke manganese, te maitai pukupuku, te maitai puna, te maitai reera, te maitai nickel, te maitai taputapu me te mate me te maitai rererangi. He mea whakamahi noa hei paparanga ātete-kakahu me te paparanga "pūmau" i roto i ngā tono mata pakeke. Ka whakapakeke te mahi tae atu ki te 200 Brinell. Ko te 312-17 te mea tino kaha ki te kume me te kaha whakaputa o ngā irahiko pania ki te kowiri tira paerewa (kāore i roto te kowiri tira takirua).
