Ukusetyenziswa kweerobhothi ze-welding kufuneka zilawule ngokungqongqo umgangatho wokulungiselela iinxalenye kunye nokuphucula ukuchaneka kwendibano yeentsimbi.Umgangatho womphezulu, ubungakanani begroove kunye nokuchaneka kwendibano yamacandelo kuya kuchaphazela isiphumo sokulandelela i-welding seam.Umgangatho wokulungiswa kweengxenye kunye nokuchaneka kwendibano ye-weldment inokuphuculwa ukusuka kule miba ilandelayo.
(1) Qokelela inkqubo yokuwelda ekhethekileyo yeerobhothi zokuwelda, kwaye wenze imimiselo yenkqubo engqongqo kubungakanani bamalungu, i-weld grooves, kunye nemilinganiselo yokuhlanganisa.Ngokuqhelekileyo, ukunyamezela kwamalungu kunye nobukhulu begroove kulawulwa ngaphakathi kwe-± 0.8mm, kwaye impazamo ye-dimension dimension ilawulwa ngaphakathi kwe-± 1.5mm.Amathuba okuba neziphene ze-welding ezifana ne-pores kunye ne-undercuts kwi-weld ingancitshiswa kakhulu.
(2) Sebenzisa izixhobo zendibano ezichanekileyo ezichanekileyo zokuphucula ukuchaneka kwendibano ye-weldments.
(3) I-Welding seams kufuneka ihlanjululwe, ingabi neoli, i-rust, i-welding slag, i-slag yokusika, njl., kunye ne-primers ethengiswayo iyavunyelwa.Ngaphandle koko, kuya kuchaphazela izinga lempumelelo ye-arc ignition.I-Tack welding iyatshintshwa ukusuka kwi-electrode welding ukuya kwi-gas shielded welding.Kwangaxeshanye, iindawo zokuwelda ziyagudiswa ukunqanda intsalela ye-slag crusts okanye iipores ngenxa ye-welding ye-tack, ukunqanda ukungazinzi kwe-arc kunye nokutshiza.
