Leliphi inqanaba lokubumba lomatshini wokuwelda amaza aphakathi?

Inqanaba lokubumba lefrikhwensi ephakathiumatshini wokuwelda indawoibhekisela kwinkqubo apho i-electrode iqhubeka ibeka uxinzelelo kwindawo ye-weld emva kokuba i-welding current inqunyulwe. Ngeli nqanaba, indawo ye-weld ihlanganiswe ukuqinisekisa ukuqina kwayo. Xa umbane ucinyiwe, undoqo otyhidiweyo uqalisa ukuphola kwaye ukhazimle ngaphakathi kwiqokobhe lesinyithi elivaliweyo, kodwa usenokungacutheki ngokukhululekileyo.

Ngaphandle koxinzelelo, i-weld point ixhomekeke kwimingxuma yokunciphisa kunye nokuqhekeka, okunokuchaphazela amandla ayo. Uxinzelelo lwe-Electrode kufuneka lugcinwe emva kokucima umbane de intsimbi etyhidiweyo iqine ngokupheleleyo, kwaye ixesha lokubunjwa lixhomekeke kubunzima bomsebenzi.

Kwizixhobo zokusebenza ezishinyeneyo ezinamaqokobhe esinyithi angqindilili ajikeleze umbindi otyhidiweyo, ukwanda koxinzelelo lokubumba kunokuba yimfuneko, kodwa ixesha kunye nobude boxinzelelo olwandisiweyo kufuneka ilawulwe ngononophelo. Ukufakwa koxinzelelo kwangoko kakhulu kunokubangela ukuba isinyithi esinyibilikisiweyo sicudiswe ngaphandle, ngelixa ukufakwa kade kakhulu kunokubangela ukuqina kwesinyithi ngaphandle kokubunjwa okusebenzayo. Ngokuqhelekileyo, ukunyuka koxinzelelo lokubumba kusetyenziswa ngaphakathi kwe-0-0.2 imizuzwana emva kokucima umbane.

Oku ngasentla kuchaza inkqubo ngokubanzi yokwakheka kwe-weld point. Kwimveliso yokwenyani, amanyathelo enkqubo ekhethekileyo ahlala amkelwa ngokusekelwe kwizinto ezahlukeneyo, izakhiwo, kunye neemfuno zomgangatho we-welding.

Kwimathiriyeli ethanda ukuqhekeka okushushu, iindlela ezongezelelekileyo zokupholisa ipulse welding zingasetyenziselwa ukunciphisa isantya sokuqina kombindi otyhidiweyo. Kwizinto ezicinyiweyo kunye nobushushu, unyango lwe-post-weld ubushushu phakathi kwee-electrode ezimbini lunokwenziwa ukuze kuphuculwe i-brittle quenching structure ebangelwa ukufudumeza ngokukhawuleza kunye nokupholisa.

Ngokubhekiselele kwisicelo soxinzelelo, i-saddle-shaped, stepped, okanye imijikelezo yoxinzelelo lwe-electrode yamanyathelo amaninzi ingasetyenziselwa ukuhlangabezana neemfuno ze-welding zamalungu anemigangatho eyahlukeneyo yomgangatho.
