Paʻi wiliwili
ʻO ka pinepine welded paipu wili puʻupuʻu ʻo ia kekahi o nā ʻāpana nui o ke kaʻina hana kuʻi, ma hope o ka wela ʻana o nā ʻaoʻao ʻelua o ka paipu i ka wela wili a me ka ʻomi ʻana i nā huahana i welded ma lalo o ke kaomi e hana i ka palaoa metala maʻamau e like me nā kristal.No ka mea, aia paha ka laulā o ka paipu a me ka mānoanoa, a me ka wela o ke kuʻi ʻana o ka nalu a me ka wikiwiki o ka wiliwili ʻana, e pili ana paha ia i ka hoʻololi ʻana i ka ikaika kaomi.Kiʻekiʻe-frequency kuʻihao paipu extrusion nui ka maʻamau e hoʻoponopono i ka mamao ma waena o ka rollers squeeze, squeeze rollers hiki nō hoʻi ke hoʻohana i ka mua a me ka ʻokoʻa hope e hoʻomalu i ka pōʻai paipu.

Ka māmā wiliwili
ʻO ka wikiwiki o ka welding kekahi o nā ʻāpana nui o ka ʻenehana welding, ʻōnaehana hoʻomehana a hoʻopaʻa ia i ka wikiwiki a me ka wikiwiki crystallization.I ka wā kiʻekiʻe-frequency welded paipu, kuʻihao maikaʻi me ka hoʻokēʻai hoʻokēʻai wikiwiki piʻi.No laila, i ka wā kiʻekiʻe-frequency welded paipu, mechanical lako a pono i loko o ka welding apparatus wae.
