Iziphene zeWelding eziqhelekileyo

Kwinkqubo yokuvelisa i-welding yensimbi, kuya kubakho ukuvela kweziphene zetsimbi ukuba indlela ye-welding ayilunganga.Ezona ziphene zixhaphake kakhulu kukuqhekeka okutshisayo, ukuqhekeka okubandayo, ukukrazuka kwe-lamellar, ukungabikho kokudibanisa kunye nokungena okungaphelelanga, i-stomata kunye ne-slag.

Ukuqhekeka okushushu.

Iveliswa ngexesha lokupholisa i-weld.Oyena nobangela mkhulu yi-sulphur kunye ne-phosphorus kwintsimbi kunye ne-welding yenza imixube ye-eutectic, imixube i-brittle kakhulu kwaye inzima.Ngexesha lokupholisa i-weld, imixube ye-eutectic iya kuba kwimeko yoxinzelelo ukuze kube lula ukuqhekeka.

Ukuqhekeka okubandayo.

Ikwabizwa ngokuba kukulibaziseka ukuqhekeka, iveliswa ukusuka kwi-200kwiqondo lobushushu begumbi.Iza kuqhekezwa emva kwemizuzu embalwa nangeentsuku ezimbalwa.Isizathu sinxulumene ngokusondeleyo kunye noyilo lwesakhiwo, izinto ze-welding, ukugcinwa, ukusetyenziswa kunye neenkqubo ze-welding.

Lamellar Ukukrazula.

Xa ubushushu be-welding bupholile ukuya kuma-degrees angama-400, enye ubukhulu bepleyiti bukhulu kakhulu kwaye nomxholo wokungcola okuphezulu, ngokukodwa umxholo wesulfure, kwaye inomnye ungqamaniso oluqinileyo kwindlela yokuqengqeleka ecaleni kwephepha lamandla aphezulu aphantsi kolwahlulo lwentsimbi. ephantsi kwamandla perpendicular ukuya ulwalathiso ukutyeba kwinkqubo welding, iya kuvelisa ulwalathiso rolling wanyathela iintanda.

Ukunqongophala kweFusion kunye nokuNgena okungaphelelanga.

Zombini ezi zizathu ziyafana, ukungafanelekanga kweparamitha yetekhnoloji, imilinganiselo kunye nemilinganiselo ye-groove, ukucoceka okwaneleyo kwe-groove kunye ne-weld surface okanye iteknoloji ye-welding engafanelekanga.

Stomata.

Esona sizathu siphambili sokuvelisa i-porosity kwi-weld inonxibelelwano kunye nekhethiweyo, egciniweyo kwaye isetyenzisiwe kwizinto ezidibeneyo, ukukhethwa kweeparamitha zenkqubo ye-welding, ukucoceka kwe-groove kunye neqondo lokukhusela le-weld pool.

I-Slag.

Uhlobo, imilo kunye nokuhanjiswa kwezinto ezingenayo i-metallic inclusions kudibaniswa kwiindlela zokudibanisa kunye nokubunjwa kweekhemikhali ze-welding, i-Flux kunye ne-weld metal.
