Umbhobho woxandeukuwelda ngokweemfuno zenkqubo kufuneka i-groove butt welding, ukuthunga indawo egciniweyo.Uyilo lwamalungu adityanisiweyo alikhonkco elibuthathaka kubunjineli be-welding.Iifom ze-Groove weld zokulawula umgangatho wangaphakathi kunye nomgangatho wokuvelisa izakhiwo ezidibeneyo zinendima ebaluleke kakhulu.

Iimfuno zenkqubo ngumaleko wokuqala wokungenwa kwe-weld kufuneka ziqinisekise ukubunjwa okuhle komva, ukuwelda okwangoku, amandla ombane we-arc, isantya sokutya kocingo kunye nohlengahlengiso lwesantya esisekwe kuhlobo lwesixhobo, isikwere kunye netyhubhu exande ukunciphisa ukugqwetheka kwe-welding, imigaqo yemveliso ye-welding ethathwe phakathi ukuya macala omabini e-segmented layered symmetrical skip welding, i-welding deformation yenziwe i-weld ethe ngqo encinci kunokuba ilungele ukusabalalisa kunye nokukhulula uxinzelelo, ukuphepha uxinzelelo olunzima kwi-welding.

Umxinwa ujingi welding yeplastiki deformation zone eyenziwe ngexesha welding kwenzeka kanye kuphela, kwaye ngenxa yokulukwa ngokuqhubekayo welding umthamo igalelo ubushushu, indawo eshushu, indawo enkulu deformation yeplastiki kubangelwa ucinezelo, ngaloo ndlela shwabana kakhulu emva deformation welding.

Xa segmentation hierarchical tsiba ukuwelda, icandelo lincinane kakhulu umaleko ngamnye, ubushushu obufunekayo lincinci, kwaye umaleko ngamnye yahlulwe ngamacandelo aliqela tsiba ukuwelda, soldering icandelo ngalinye ngokusisiseko kwakhona ukudala intsimi ubushushu kwipleyiti ebandayo ngalo lonke ixesha ukuvela indawo emxinwa yokuguqulwa kweplastiki, kwaye ngaloo ndlela ububanzi be-avareji ye-deformation yeplastiki incinci kune-welding ehambelanayo ehambelanayo, i-longitudinal shrinkage incinci, xa kuthelekiswa ne-welding eqhubekayo ejikelezayo i-welding swing xa igcwele incinci.
