Le weld - ngendlela ethembekileyo ukudibanisa iinxalenye

Le weld amatshatshazi wokujoyina iinxalenye ezimbini okanye ngaphezulu, oluthi luqokelelane yi inkqubo crystallization le etyhidiweyo metal ngoku kwi weld pool. Le metal ukuba welding kwinxalenye uxhulumaniso sakhiwa ngomxube ngezinto lokufaka kunye preform otyhidiweyo.

Ukuhlelwa ezi zihlanganisi kakhulu kakhulu, nto leyo evumela ukuba ukujonga uhlobo weld ngokulula. Umzekelo, kwi kuhlobo yokusebenza ukwahlula amalungu single- kunye amabini, kwaye ulwalathiso nempembelelo - ngokungqalileyo, ukwakha, idibene, kunye elibhalwe ngokumileyo. Ngaphezu koko, ukuma komhlaba kwakhona kunempembelelo enkulu. Kolu didi ukwahlula oxwesileyo kwaye nkqo, isilingi kunye uxhulumaniso ezantsi.

Wonke weld unohlobo iimpawu zangaphandle, nto leyo eye iintlobo ezintathu: a buthathaka, kwaye yaphuculwa. Ngenxa yoko, imilo cross somhlathi ukwahlula kwikona kunye lempundu amalungu. Ngenxa yonke le iyantlukwano, ungafumana inani elikhulu ukuxhumana, umzekelo, umnqamlezo, tee, okanye lempundu. Kugcine kusetyenziswa kuphela amalungu ndandisisigculelo eziluhlobo luyaqhubeka. Eyona phawu eyahlula sasingenamthungo phakathi kwezinye izinto, le nxalenye Cutting Edge, okanye mandithi imilo wabo kwicandelo emnqamlezweni. Zezona lwimi zisetyenziswa olunye-anababini-kabini, kujikwa, iimilo rectilinear, kukho kwakhona ayimveliso apho akukho beskrini ahlabayo. iintlobo Complex onyango zithathwa ngohlangothi V- kunye X-ezimile. Ngenxa yoko, le weld umtya kwakhona umahluko lweentlangothi yoyilo ifomu, kwakunye nohlobo welding: rhoqo okanye discontinuous.

Zonke ezikhoyo iintlobo amalungu kuvumela ukudityaniswa iinxalenye olulingana yahlukene ezahlukeneyo zesinyithi. Ukongeza, ukuba iphuhlise ezahlukahlukeneyo ezinjongo ukuphucula iimpawu weld kunye nokwandisa ukuthembeka inamehlo enjalo. Le misebenzi kungathathwa njengesisebenzayo: ukusetyenziswa kwezinto lokufaka ezizodwa; segesi izahlulo kwi umoya igesi elikhuthaza ukususwa oksijini evela kummandla arc; ukusetyenziswa obhobhozayo, kunye nabanye.

Le weld iya kwenziwa ngokuzenzekelayo, semi-ngokuzenzekelayo okanye ngesandla. Nganye kwezi ndlela uneempawu zawo, kwaye kungoko ingasetyenziswa kwiindawo ezahlukahlukeneyo. Oku kukuvumela ukuba kwandiswe uluhlu nesicelo iwelding.

indawo welding, apho amalungu uxhulumaniso, ufakwa neengxaki ezinkulu thermal. iinkqubo ezifanayo zaziwa ukuba kukhokelela ekuguqukeni lonikezelo kunye nohlobo nemikhosi okwenzekayo. Oku kuchaphazela ukuthembeka obuchopho.

Ipharamitha ukuba ziimpawu weld, bezalana ngqo imilinganiso yalo kwijometri. Le nzuzo ixabiso ububanzi blunting, ubungakanani abana nezinyuko ngala macandelo welding.

Lawula welds eyenziwe ngomnye ngumvelisi, njengoko kuchaphazela umgangatho, ukuthembeka kunye nokomelela kwalo hlobo ezimbaxa.
