Te kaupapa o te welding

Ko te miihini rewa wera te nuinga o te whakamahi i te mana o te pāmahana ki te whakahaere i te pāmahana o te pokepokea ai mahi i runga i te pereti whakawera hei wetewete i te hua.I muri i te ekenga o te hangai mahi ki te pāmahana whakahiato kua whakaritea, ka heke te rango ki te whakahāngai i te peeke mahi ki te tohu whakahiato o te hua, ka timata te rewa te ira whakapiri.I raro i te pehanga o te rango, ka tae te tohu whakapiri i runga i te mata o te hua ki tetahi tohu o te rewa, ka piki te rango, ka pakari i te pāmahana rūma ki te hanga i tetahi mekameka ngota ngota totoka ki te whakatutuki i te kaupapa o te whakapiri.
