Nui nā ʻano kuʻi uila (erw), a ʻekolu ʻano o ka wiliwili, ka wili wili, ka kuʻekuʻe wāwae a me ka wili projection.

ʻO ka mea mua, ka welding spot
ʻO ke kuʻi koʻikoʻi kahi ʻano o ka hoʻoheheʻe ʻana i ka uila kahi i hui ʻia ai ka weld i loko o kahi hui ʻūhā a kaomi ʻia ma waena o nā electrodes columnar ʻelua e hoʻoheheʻe i ka metala kumu e ke kūpaʻa uila e hana i kahi hui solder. Hoʻohana nui ʻia ka wiliwili wahi no ka wiliwili pā lahilahi.

Kaʻina wiliwili kiko:
1. Preloading e hōʻoia i ka pilina maikaʻi me ka mea hana.
2. Ka mana, i hana ʻia ka weld i kahi nugget a me ke apo plastic.
3. Ka hoʻokuʻu ʻana i ka mana, i maʻalili a crystallize ka nugget ma lalo o ke kaomi, a hana i kahi hui welded me ka ʻano paʻa, ʻaʻohe puka shrinkage a māwae.

ʻO ka lua, wili wili
Hoʻohana nui ʻia ka welding seam no ka welding welds i maʻamau a koi ʻia ke sila. ʻO ka mānoanoa o ka hui ma lalo o 3 mm.

ʻO ke kolu, ʻo ka wili puʻupuʻu
ʻO ka welding butt kahi ʻano hana kuʻi kūʻē e hoʻopaʻa ʻia ai kahi paipu alloy 35Crmo ma ka ʻaoʻao pili āpau.

ʻO ka hā, hoʻoheheʻe projection
ʻO ka wiliwili projection he ʻano like ʻole o ka wiliwili wahi; aia nā puʻupuʻu i hana mua ʻia ma luna o kahi mea hana, a hiki ke hana ʻia hoʻokahi a ʻoi aku paha nā nuggets ma ka hui i ka manawa.
