Mbiri yachitukuko cha makina owotcherera: yokhazikika pamakina owotcherera amagetsi

Kuwotcherera kwakhala njira yofunika kwambiri popanga ndi kumanga kwazaka zambiri, ndipo yasintha kwambiri pakapita nthawi. Kukula kwamakina owotcherera, makamaka zowotcherera magetsi, zasintha kwambiri makampani, kukulitsa luso komanso kulondola kwazitsulo zojowina.

Mbiri yamakina owotcherera idayamba chakumapeto kwa zaka za m'ma 1800, pomwe ukadaulo wowotcherera arc unayambitsidwa koyamba. Njira zowotcherera zakale zinkadalira malawi a gasi, koma kubwera kwa magetsi kunatsegula njira zatsopano zopangira zitsulo. Mu 1881, kuwotcherera kwa arc kudayamba, ndikuyika maziko azinthu zamtsogolo. Pofika m'zaka za m'ma 1920, zowotcherera zamagetsi zinakhala zofala, zomwe zinapangitsa kuti kuwotcherera kukhale kolamulirika komanso kothandiza.

Kukhazikitsidwa kwa thiransifoma m'zaka za m'ma 1930 kunali chinthu chofunikira kwambiri pakupanga makina owotcherera. Kukonzekera kumeneku kunapanga njira yokhazikika, yodalirika, yomwe inali yofunika kwambiri kuti tipeze ma welds apamwamba kwambiri. Ukadaulo ukupita patsogolo, ukadaulo wa inverter udayamba m'ma 1950, ndikupititsa patsogolo magwiridwe antchito a makina owotcherera. Makinawa anakhala ophatikizika, osavuta kunyamula, komanso osagwiritsa ntchito mphamvu zambiri, zomwe zinapangitsa kuti anthu ambiri azizigwiritsa ntchito.

M'zaka zaposachedwa, kupita patsogolo kwaukadaulo wa digito kwasintha ma welder kukhala makina otsogola okhala ndi zinthu monga makonda okonzekera, kuyang'anira nthawi yeniyeni komanso njira zotetezera chitetezo. Owotcherera amakono tsopano ali osinthasintha kotero kuti ogwira ntchito amatha kupanga njira zosiyanasiyana zowotcherera, kuphatikizapoMIG, TIG ndi kuwotcherera ndodo, ndi chipangizo chimodzi chokha.

Masiku ano, zida zowotcherera zakhala gawo lofunikira kwambiri m'mafakitale kuyambira magalimoto mpaka zomangamanga, zomwe zikuwonetsa kupitilira kwaukadaulo wowotcherera. Kuyang'ana m'tsogolo, kupanga makina owotcherera kupitilira kuyang'ana pa zodziwikiratu, luntha lochita kupanga, komanso kukhazikika, kuwonetsetsa kuti kuwotcherera kumakhalabe kothandiza komanso kosunga chilengedwe. Kupanga makina owotcherera ndi umboni wa nzeru za anthu ndi kufunafuna kosalekeza kwa luso la ntchito yachitsulo.
