Ukusikwa kweebha → ukugoba okubandayo → ukudibana → ukuwelda → ukulinganiswa okuphambili → unyango lobushushu → ukulinganiswa kwesibini (ubungqina) → ukuhlolwa. Ukuwelda kunye nonyango lobushushu ziinkqubo eziphambili ekuvelisweni kwetsheyini yentsimbi ejikelezileyo, echaphazela ngqo umgangatho wemveliso. Iiparamitha zokuwelda zesayensi zinokuphucula isivuno kwaye zinciphise iindleko zemveliso; Inkqubo efanelekileyo yonyango lobushushu inokunika amandla apheleleyo kwiimpawu zezinto kwaye iphucule umgangatho wemveliso.
Ukuze kuqinisekiswe umgangatho wokuwelda we-minning round link steel chain, ukuwelda ngesandla kwe-arc kunye nokuwelda kwe-resistance butt kuye kwasuswa. Ukuwelda kwe-Flash butt kusetyenziswa kakhulu ngenxa yezinga layo eliphezulu lokuzenzekela, amandla aphantsi okusebenza, umgangatho wemveliso ozinzileyo kunye nezinye iingenelo ezibalaseleyo.
Okwangoku, indlela yokufudumeza rhoqo kunye nokufutha i-medium frequency induction heating isetyenziswa ngokubanzi kunyango lobushushu lwe-mining round link steel chain. Ingongoma yokufudumeza rhoqo kukuba isakhiwo se-molecular sento sishukunyiswa phantsi kwentsimi ye-electromagnetic, kwaye i-molecule ifumana amandla kwaye ingqubane ukuze ivelise ubushushu. Xa kuqhutywa unyango lobushushu lwe-medium frequency induction heat, i-inductor iqhagamshelwe kunye ne-medium frequency alternating current ye-frequency ethile, kwaye i-workpiece ihamba ngesantya esifanayo kwi-sensor, ukuze i-induction current ene-frequency efanayo kunye necala elichaseneyo iveliswe kwi-workpiece, eya kutshintsha amandla ombane abe ngamandla obushushu, kwaye i-workpiece iya kufudunyezwa kubushushu obufunekayo ngokucima kunye nokufutha ngexesha elifutshane.
Ukufudumeza okuphakathi okubangelwa kukufudumeza okukhawulezayo, ukucocwa okuncinci, ulwakhiwo olucolekileyo lokucima kunye nobukhulu be-austenite grain emva kokucima, okuphucula amandla kunye nokuqina kwekhonkco lekhonkco. Kwangaxeshanye, kukwaneengenelo zokucoceka, ukulungiswa okulula kunye nokusebenza kakuhle kwemveliso. Kwinqanaba lokupholisa, ubushushu obuphezulu bokupholisa kwindawo yokupholisa ikhonkco lekhonkco bunokuphelisa uxinzelelo lwangaphakathi lokucima ngexesha elifutshane, olunefuthe elibalulekileyo ekuphuculeni ubungqingqwa kunye nokuqina kwendawo yokupholisa ikhonkco lekhonkco kunye nokulibazisa ukuqaliswa nokuphuhliswa kwemifantu. Ubushushu bokupholisa phezulu kwegxalaba buphantsi, kwaye ubunzima buphezulu emva kokupholisa, okulungele ukuguguleka kwekhonkco lekhonkco kwinkqubo yokusebenza kunye nxamnye nehinge phakathi kweekhonkco zekhonkco kunye ne-sprocket meshing.
