ʻO ka welding kiʻekiʻe ka hoʻohana ʻana i ka hopena o ka ʻili e hana i ka ikehu kiʻekiʻe o kēia manawa e kau ʻia ma luna o ka ʻili o ka mea hana;Hoʻohana ʻia ka hopena pili e hoʻomalu i ke kūlana a me ka laulā o ke ala kahe kahe alapine kiʻekiʻe.ʻO ka wikiwiki o ke au he wikiwiki loa, hiki iā ia ke wela i ka lihi o ka pā kila pili i ka manawa pōkole loa, hoʻoheheʻe, a hoʻomaopopo i ka docking ma o ka extrusion i kēlā me kēia mea i kona pono ponoʻī, akā he mau hemahema.He mea maʻamau ka nānā ʻana i nā koho kikoʻī e like me nā kūlana kikoʻī.
ʻO ke kaʻina hana o ka hana ʻana i ka Electric Resistance Welding (ERW) Pipe penei:
E wehe i ka ʻili pāpaʻi → Hoʻopololei i ka wili ʻana → ʻoki ʻoki ʻia → ʻoki kuʻekuʻe kuʻekuʻe → Nānā ʻike → Nānā Ultrasonic → Nānā X-ray → Hoʻāʻo ʻana i ke kaomi → Chamfering flat → Nānā hope
ʻO ka paipu ʻole a i ʻole ka uhi ʻeleʻele / Varnish (hoʻopili ʻia);
i loko o nā pūʻolo a i ʻole i wehe ʻia;
ʻO nā hopena ʻelua me nā mea pale hope;
Plain end, bevel end(2"a ma luna me ka bevel welau, degere: 30~35°), threaded a me ka hoohui;
Hoailona.
