Kukaniza kuwotchereraNjira idakula mwachangu kuyambira pomwe idakhazikitsidwa chakumapeto kwa zaka za zana la 19, makamaka ndi kukwera kwamakampani opanga magalimoto ndi mabizinesi ena, kugwiritsa ntchito komwe kukuchulukirachulukira.Malinga ndi ziwerengero, njira yowotcherera yomwe ilipo pano ndi pafupifupi 1/4 ya ntchito yonse yowotcherera.Ndi zaukali mbali okonzeka, mmodzi wa msonkhano kupanga ndondomeko.

Choyamba, kukana kuwotcherera ndi kufunikira kwa kuthamanga pansi kuti amalize kuwotcherera, kotero kaya ndi yochokera ku mapangidwe a solder olowa kapena kuchokera kumalo ena omangira kuwotcherera komwe kuwotcherera kumakhala kosavuta, pamene kukana kuwotcherera kuli ndi zofunika kwambiri zina zowonjezera. kuwotcherera zakuthupi makhalidwe, amene welded safuna kuchita wothandiza, iwonso safuna kugwiritsa ntchito mawaya ndi ndodo kuwotcherera filler kuchita zimenezi, motero kwambiri kupulumutsa mavuto ambiri mtengo, komanso kwambiri kuonjezera mphamvu.

Chachiwiri, kukana kuwotcherera ndi ntchito yosavuta yomwe, pansi pa ntchito yosavuta panthawi imodzimodziyo, m'malo otsekemera omwe ali ndi ubwino wambiri, kwenikweni sangathe kuchita utsi.

Poyerekeza ndi luso kuwotcherera ochiritsira, kukana kuwotcherera ali ndi ubwino waukulu zotsatirazi:
1) kutentha kumakhala kokhazikika, nthawi yotentha ndi yochepa, yocheperako.
2) ndondomeko metallurgical ndi losavuta, ndipo zambiri safuna kudzaza zakuthupi ndi zosungunulira Sikuti kuteteza mpweya.
3) amatha kusintha mitundu ingapo yofananira ndi kuwotcherera zitsulo zofananira, kuphatikiza kuwotcherera kwa mbale yachitsulo.
4) Njirayi ndi yosavuta, yosavuta kugwiritsa ntchito makina ndi makina, ntchito isanayambe sikufuna kuphunzitsidwa kwa nthawi yaitali kwa ma welders.
5) welded ndi zokolola zambiri ndi mtengo wotsika.
6) malo abwino ogwirira ntchito ndi kuipitsa.
