He aha He Rakau Hiko?

He waea whakarewa te welding electrodes kua tunua ki runga paninga matū.Ka whakamahia te rakau ki te pupuri i te pewa whakapiri me te whakarato i te whakarewa whakakii e hiahiatia ana mo te hononga kia paiherea.Ka tiakina e te paninga te whakarewa mai i te kino, ka whakapumau i te pewa, ka pai ake te paihere.Ko te diameter o te waea, he iti ake te paninga, ka whakatau i te rahi o te rakau whakapiri.Ka whakaatuhia tenei ki nga hautau o te inihi penei i te 3/32″, 1/8″, 5/32 ranei.Ko te iti ake o te diameter he iti ake te waa me te iti ake o te whakarewatanga whakakii.

Ko te momo o te whakarewa turanga e paiherea ana, ko te tukanga whakapiri me te miihini, me etahi atu tikanga e whakatau ana i te ahua o te hiko hiko e whakamahia ana.Hei tauira, ko te waro iti, "te rino ngawari" ka hiahiatia he kaitao maitai.Ko te whakarewa i te rino, te konumohe, te parahi ranei, me rereke nga rakau me nga taputapu.

Ko te paninga rere i runga i nga hiko e whakatau ana me pehea te mahi i te waa o te mahi whakaahuru.Ko etahi o te paninga ka wera me te rere o te wera ka puta he auahi, ka mahi hei parepare huri noa i te "puna wai" hei whakamarumaru i te hau huri noa.Ka rewa tetahi wahanga o te rere, ka uru ki te waea, ka rewa nga poke ki te mata.Ko enei poke e kiia ana ko "slag."He pakarukaru, he ngoikore te wea kua oti ki te kore mo te rere.Ka whakamataohia te hononga paiherea, ka taea te tango i te para.Ka whakamahia te hama maramara me te paraihe waea ki te horoi me te tirotiro i te paihere.

Ka whakarōpūhia nga irahiko whakarewa-arc hei irahiko korekore, i nga irahiko whakakikorua marama, me te pewa whakamarumaru, i nga hiko whakakakahu taumaha ranei.Ko te momo e whakamahia ana e whakawhirinaki ana ki nga ahuatanga motuhake e hiahiatia ana: te aukati i te waikura, te ngongo, te kaha tensile teitei, te momo whakarewa turanga hei paihere;me te tūnga o te weld he papatahi, he whakapae, he poutū, kei runga ranei.
