He maha nga ahumahi e whakamahi ana i nga welders i nga umanga - te hanga, te hanga, te hanga kaipuke me te reriwe hei whakaingoa i etahi.Ahakoa he mahinga noa, me aro ki nga taipitopito, he pai ki te mohio ki etahi kupu matua e pa ana ki taua mahi.Pērā i ngā hātepe, ka pai ake te māramatanga, ka pai ake ngā hua.
Kohanga manu
Ko te weriweri o te waea whiri i roto i nga roera puku o te kai waea.I te nuinga o te wa ka kore te waea i te ara whangai maeneene na te mea he poto rawa te tapahi o te riipene, he he te rahi o te raina, te pito ranei i whakamahia, he he ranei nga tautuhinga puku.Whakatauhia tenei take ma te kuti tika i te raina me te whakarite kia maeneene, kia tika hoki te ara whangai o te waea.
Burnback
Ka puta ina rewa te waea ki roto i te pito whakapā i mua i te taenga atu ki te mea mahi.Ka puta mai i te tawhiti whakapā-tip-ki-mahi (CTWD) hē — te tawhiti i waenga i te pito o te pito me te whakarewa turanga — he puhoi rawa ranei te tere whangai waea (WFS).Ka taea hoki te take mai i te hee te whakapai i te raina me nga tawhā hē.Whakaorangia te raruraru ma te whakanui ake i te WFS, te whakatikatika i te CTWD, te tarai i te raina kia rite ki te tohutohu a te kaihanga me te whakarereke i nga tawhā weld.
Te reeti whakatakoto
E tohu ana ki te nui o te konganuku whakakī ka tukuna ki roto i te hononga paihere i roto i te waa kua tohua, ka inehia ki te pauna, kirokaramu ranei ia haora (pauna/haora, kg/haora ranei).
Whakamutua
He koha i roto i te hanganga o te weld e kore e puta he tupono ki te kore.He rereke ki te koha o te weld ka pa ki te pono o te weld i te wa e mahi ana.
Te huringa mahi
E tohu ana ki te paheketanga o te wa i roto i te 10 meneti ka taea te whakamahi i te pu i te amperage motuhake (waa arc-on) me te kore e wera rawa ki te hapai, ki te wera ranei.Ko te huringa mahi a te pu ka pa ki te momo hau whakamarumaru e whakamahia ana mo te whakapiri.Hei tauira, ka whakatauhia he pu MIG ki te 100% huringa mahi me te hau parepare 100% CO2, ko te tikanga ka taea e ia te whiri i nga meneti 10 katoa kaore he raru;he 60% ranei te whakatauranga pu me nga hau whakauru.
toronga hiko
Ko te tawhiti ka toro atu te waea whakapiri mai i te pito o te pito whakapiri ki te wahi rewa ai te waea.Ka piki te toronga hiko, ka heke te amperage, ka whakaiti i te urunga tahi.Ka kiia ano ko te tawhiti pito-ki-mahi.
Rohe kua pangia e te wera
I te nuinga o te wa ka kiia ko HAZ, ko te waahanga o te papanga turanga e karapoti ana i te raima kaore ano kia rewa engari kua rerekee ona ahuatanga ki te taumata microstructure na te whakauru wera.Ka taea te pakaru i konei.
Te whakakotahitanga kore
Ka kiia hoki ko te kore o te whakakotahitanga, ka puta mai i te kore e whakakotahi te weld ki te papanga turanga, ki te paahi weld o mua ranei i roto i te weld multi-pass.Ko te tikanga, he hua na te he koki pu MIG.
Porosity
He kohao-rite te korenga ka puta ina mau te hau i roto i te paihere i runga i te pakaritanga o te puna rewa whakarewa.Ko te nuinga o nga wa ka puta mai na te kino o te whakamarumaru o te hau me te poke o nga rawa turanga.
Te kuhu weld
E tohu ana ki te tawhiti o te whakakorikori i raro i te mata o te papanga turanga.Ko te urunga o te weld karekau i tino whakakiia te pakiaka o te hononga.
