Pehea e hōʻike ai i ka pae o ka wiliwili kila: ʻO ke kila wiliwili e pili ana i ke kila kalapona no ka wiliwili, ke kila kila no ka wiliwili, ke kila kuhiliʻole no ka wiliwili, a me nā mea ʻē aʻe. pae kila wiliwili. No ka laʻana H08, H08Mn2Si, H1Cr18Ni9. No ke kila welded kiʻekiʻe kiʻekiʻe, e hoʻohui i ka hōʻailona "A" ma ka hopena o ka papa. No ka laʻana H08A, H08Mn2SiA.

Hoʻohana maʻamaupaipu kila weldedua māhele ʻia i ʻekolu mau ʻano e like me nā kaʻina hana welding i hoʻohana ʻia i kā lākou hana.
① ʻO ka hoʻomau ʻana o ka umu ahi (forge welding) paipu kila: ʻike ʻia ia e ka hana kiʻekiʻe o ka hana a me ke kumu kūʻai haʻahaʻa, akā ʻaʻole paʻa ka hui ʻana o ka hui welded, maikaʻi ʻole ka maikaʻi o ka weld, a ʻilihune nā waiwai mechanical piha.

② ʻO ka paipu kila i hoʻopaʻa ʻia e kūʻē: ʻike ʻia ia e ka hana kiʻekiʻe o ka hana ʻana, kiʻekiʻe kiʻekiʻe o ka automation, ʻaʻohe pono o nā koʻokoʻo wili a me ka flux i ka wā wili, liʻiliʻi ka pōʻino i ka metala kumu, a me ka liʻiliʻi deformation a me ke koena koʻikoʻi ma hope o ka wili. Eia nō naʻe, paʻakikī kāna mea hana, ʻoi aku ka kiʻekiʻe o ka hoʻopukapuka ʻana o nā lako, a ʻoi aku ka kiʻekiʻe o nā pono o ka ʻili o nā hui welded.

③Arc welded steel pipe: ʻO kona ʻano ʻo ia ka hoʻokō ʻana o ka hui welded i ka hoʻopaʻa ʻana i ka metallurgical paʻa, a hiki i nā ʻano mechanical o ka hui ke hoʻokō piha a kokoke paha i nā waiwai mechanical o ka mea kumu. E like me ke ʻano o ka weld, hiki ke hoʻokaʻawale ʻia nā paipu kila arc i nā paipu humuhumu pololei a me nā paipu wiliwili ʻia; e like me nā ʻano pale ʻokoʻa i hoʻohana ʻia i ka wā wili, hiki ke hoʻokaʻawale ʻia nā paipu kila arc welded i nā paipu kila arc i hoʻoheheʻe ʻia a hoʻoheheʻe ʻia nā paipu kila. ʻElua ʻano o nā paipu kila welded.
