1. Amaqamza
Amaqamza avela kumbindi we weld bead, kwaye ihydrogen isafihlwe ngaphakathi kwintsimbi yeweld ngendlela yamaqamza. Isizathu esona sizathu kukuba i-welding wire kunye ne-flux inomswakama phezu komhlaba kwaye isetyenziswe ngokuthe ngqo ngaphandle kokumisa. Kwakhona, okwangoku kuphezulu kakhulu ngexesha lenkqubo ye-welding. Incinci, isantya se-welding sikhawuleza kakhulu, kwaye oku kuya kwenzeka kwakhona ukuba ukuqiniswa kwentsimbi kuyakhawuleza.

2. I-Undercut
I-Undercut yigroove emile okwe-V ebonakala kwincam ye weld ecaleni komgca osembindini we weld. Esona sizathu sesokuba isantya se-welding, okwangoku, i-voltage, kunye nezinye iimeko azifanelekanga. Phakathi kwabo, isantya se-welding siphezulu kakhulu kwaye ikhoyo ngoku ayifanelekanga. Kulula ukubangela iziphene ze-undercut.

3. Ukuqhekeka kwe-thermal
Unobangela wokuqhekeka okutshisayo kuxa uxinzelelo lwe-weld luphezulu kakhulu, okanye xa i-SI silicon element kwi-weld metal iphezulu kakhulu, kukho olunye uhlobo lokuqhekeka kwesulfure, indawo engenanto yipleyiti enendawo eyomeleleyo yokwahlula isulfure (yeye Intsimbi ebilayo ethambileyo), iintanda ezibangelwa yi-sulfide engena kwintsimbi ye-weld ngexesha lenkqubo ye-welding.

4. Ukungena kwe-welding eyaneleyo
Ukugqithwa kwentsimbi ye-welds yangaphakathi nangaphandle ayanele, kwaye ngamanye amaxesha i-welding ayingenanga.
Indlela yokubala umbhobho wentsimbi odityanisiweyo: (i-diameter yangaphandle - ubukhulu bodonga) * ubukhulu bodonga * 0.02466 = ubunzima ngemitha nganye yombhobho wentsimbi odityanisiweyo {kg
Ukubalwa kombhobho wentsimbi evuthisiweyo: (ububanzi bangaphandle - ubukhulu bodonga) * ubukhulu bodonga * 0.02466 * 1.06 = ubunzima bombhobho wentsimbi odityanisiweyo ngemitha nganye {kg
