Ndi chitoliro chofanana ndi makulidwe a chitoliro, mphamvu yotulutsa yomweyi, liwiro la Makina Opangira Chitoliro cha Zitsulo pamalowa litha kukhala lachangu kapena pang'onopang'ono.
Pamene chubu mphero zida ndi chimodzimodzi lamba zitsulo, chinthu chachikulu zimakhudza liwiro kuwotcherera makamaka ndondomeko kuwotcherera.Ngati kuwotcherera sikuli bwino, ming'alu, pansi, slag inclusions, kulowetsedwa, ndi zina zotero zimakhala zosavuta.
1. Kulowa kosakwanira: otsika kuwotcherera panopa, kuthamanga kwambiri kuwotcherera liwiro, zachilendo kuwotcherera mfuti ngodya, etc. sachedwa zilema monga osakwanira malowedwe.Kuwotcherera koyenera komweko komanso kusintha kolondola kwa ngodya yamfuti yowotcherera kumatha kupewa kulowa kosakwanira.
2. Oxidation kwambiri: panthawi yodzisungunula, chipangizo chodzaza mphamvu mu chubu chimalephera kupereka chitetezo chabwino, ndipo kumbuyo kwa weld kudzakhala oxidized;Kutetezedwa kosakwanira kwa dziwe losungunuka komanso kutha kwa waya wowotcherera panthawi yowotcherera, kapena zonyansa za okosijeni pamwamba pa waya wowotcherera nazonso.
3. Kuphatikizidwa kwa Slag ndi Tungsten Kuphatikizidwa: Panthawi yowotcherera, ngati mapeto a waya wowotcherera amachoka kumalo otetezera argon panthawi ya kutentha kwakukulu, adzakhala oxidized mumlengalenga.Pamene kuwotchereranso, mapeto a waya oxidized satsukidwa ndi kutumizidwa ku kusungunuka Mu dziwe, amaweruzidwa kuti slag kuphatikizidwa mu mayeso fracture;ngati kutalika kwa tungsten electrode kuli kwakukulu kwambiri, tochi yowotcherera idzakhala yosakhazikika.Pambuyo pakuwotcherera kwa tungsten ndi waya wowotcherera kapena ma elekitirodi a tungsten ndi dziwe losungunuka, kuwotcherera sikutha, zomwe zimapangitsa kuphatikizika kwa tungsten.
4. Concave: Panthawi yowotcherera, nyaliyo imasinthasintha kwambiri, kotero kuti kutentha kwa arc sikungathe kukhazikika pamizu, zomwe zimapangitsa kuti pakhale concave phenomenon pomwe kuwotcherera kumbuyo kumakhala kotsika kuposa pamwamba pa chidutswa choyesera.Kutentha kwa arc kumakhazikika pamizu kwambiri momwe kungathekere, ndipo waya wowotcherera wa malo amagwiritsidwa ntchito powotcherera pamwamba kuti apewe kupindika.
