1. Mapupu
Mabhururu anowanzoitika pakati peiyo weld bead, uye haidrojeni ichiri yakavanzwa mukati mesimbi weld mumhando yemabhuru. Chikonzero chikuru ndechekuti welding wire uye flux ine hunyoro pamusoro uye inoshandiswa zvakananga pasina kuomesa. Zvakare, ikozvino yakakwira zvakanyanya panguva yewelding process. Diki, iyo welding yekumhanyisa inokurumidza, uye izvi zvichaitikawo kana kusimba kwesimbi kuchikurumidza.

2. Undercut
Undercut igororo rakaita seV rinooneka kumucheto kweweld richitevedza mutsetse wepakati we weld. Chikonzero chikuru ndechekuti kumhanya kwewelding, ikozvino, voltage, uye mamwe mamiriro haana kufanira. Pakati pavo, welding speed yakanyanyisa uye ikozvino haina kufanira. Zviri nyore kukonzera undercut defects.

3. Kuputika kwemafuta
Chikonzero chekutsemuka kunopisa ndechekuti weld stress yakakwira zvakanyanya, kana iyo SI silicon element mu weld metal yakakwira zvakanyanya, pane imwe mhando yekutsemuka kwesarufa, iyo isina chinhu iplate ine yakasimba sulfur segregation zone (ndeye Simbi yakapfava), makatsemuka anokonzerwa nesarufidhi achipinda musimbi yeweld panguva yewelding.

4. Kusakwana welding kupinda
Iyo simbi inopindirana yemukati nekunze welds haina kukwana, uye dzimwe nguva welding haina kupindwa.
Kuverengera nzira ye welded simbi pombi: (yekunze dhayamita - madziro ukobvu) * madziro ukobvu * 0.02466 = uremu pamamita epaipi yesimbi yakashongedzwa {kg
Galvanized simbi pombi kukarukureta: (kunze dhayamita - madziro ukobvu) * madziro ukobvu * 0.02466 * 1.06 = uremu welded simbi pombi pa mita {kg
