Kunzwisisa mamwe maitiro akakodzera eMIG welding anogona kubatsira velders kuwana yakanaka weld mhando uye kudzivirira kushushikana uye mutengo we rework.Zvese kubva pakumisikidzwa kwakaringana kweMIG welding pfuti yekufamba kona uye kumhanya kwekufamba kunogona kuita mhedzisiro.
Funga nezvemaitiro mana anokurudzirwa:
1.maoko kuti atsigise uye azvichengete ari kana kuti pazasi pegokora refu.Iyi nzira haingoite kuti zvive nyore kugadzira weld yemhando, asi inobatsirawo kuvandudza ergonomics.Izvo zvinonyanya kukosha kune welders welding kwenguva yakareba, saka vanogona kudzivirira kukuvara.
2.Welders vanofanira kuchengetedza contact-tip-to-work distance (CTWD) inenge 3/8 kusvika 1/2 inch ye short-circuit welding uye yakakomberedza 3/4 inch ye spray transfer MIG welding.
3.Shandisa nzira yakakodzera yekufamba.Pakusunda welding, mawelder anofanira kubata pfuti pakona yegumi-degree.Iyi nzira inogadzira bhiza rakakura rine kushomeka kwemajoini.Kune nzira yekudhonza, mawelder anoshandisa kona imwechete, kukwevera pfuti kumuviri wavo.Izvi zvinoguma nekupinza kwakawanda uye nhete weld bead.
4.Chengetedza kukurumidza kufamba kunoenderana newaya kumucheto kunotungamirira weld pool.Kumhanya zvakanyanya kwechinhambwe chekufamba kunogadzira bhero rakatetepa risinganyatso sunga pazvigunwe zveweld uye rinogona kushaya pekupinda kwakaringana.Kufamba zvishoma nezvishoma kunogadzira weld yakakura, zvakare isina kukwana kupinda.Zvose zvinononoka uye zvinokurumidza kufamba zvinomhanya zvinogona kukonzera kupisa-kuburikidza nesimbi dzakatetepa.
Sezvinoita chero nzira yewelding, kudzidzira chikamu chikuru cheMIG welding kubudirira.Pamwe chete nemaitiro akanaka, zvakakoshawo kugadzirira nemazvo uye kuchenesa hwaro zvinhu usati welding uye kuchengetedza iyo MIG welding pfuti uye zvinoshandiswa nemazvo.Izvi zvinogona kudzikisira nguva yekugadzirisa nyaya dzemidziyo kana kugadzirisa hurema hwe weld uye matambudziko akadai sekushaya waya yekudyisa.
