Submerged arc welding is arc welding pasi pe flux layer combustion nzira. Welding arc pakati pewaya uye weldment inopisa kupisa kwearc uye arc welding waya inopera padyo nebhesi simbi uye solder inonyunguduka, ramba uchidyisa waya, uye uchienderera neimwe nzira, arc weld dziva simbi yakanyungudutswa inobviswa kuti isimbise iyo yakanyungudutswa. solder inosimbiswa kuita ganda rinovhara pamusoro pe weld slag, slag yemvura yakanyungudutswa uye weld metal yekudzivirira kubva kune arcing uye dziva nekunze kwemhepo kupindira.

Submerged arc welding arc, waya, waya uye shift interrupter chiito chakadaro chinowanzoitwa nemuchina, inozivikanwa seyakanyura arc welding. SAW ine mabhenefiti anotevera: ① dhigirii repamusoro remakanika, kune mawelder anoda hunyanzvi hwakaderera; ② welding ikozvino, inogona kuderedzwa weldments groove, yakakwirira welding kunyatsoshanda; ③ inogona kupatsanurwa kubva yakanyungudutswa solder simbi kusangana nemhepo, inodzivirira mhedzisiro yakanaka, yakakwirira weld mhando; ④ yakafukidzwa nearc radiation, mamiriro ekushanda ari nani. Izvo zvakashata ndezvekuti chete mune furati chinzvimbo welding, welding midziyo uye tooling midziyo inoda.

High-frequency welding to high frequency current heat ye workpiece, uyezve kushandisa pressure welding joints (ona mufananidzo) inoumbwa. Iyo yakakwira-frequency yazvino inonamirwa pamwe nepamusoro pe conductor uye inoyerera ichifamba munzira yekushoma inductance pamusoro pemusimboti, iyo yazvino ichave yakanyungudutswa yekupisa kweiyo workpiece pamusoro kuti isimbiswe, iyo thermoplastic mamiriro asvikwa, kana chikamu chakanyungudutswa nyika, extruding. iyo simbi yakanyungudutswa pane workpiece uye kudzvanya simbi oxide, inoumbwa nemajoini akasungwa. High-frequency welding yakajairika frequency range ye60 kusvika 500 kHz. High frequency resistance welding high frequency welding points uye maviri akakwira-frequency induction welding.

① Yakakwira Frequency Resistance Welding: iyo yekubata nevhiri kana se-sub-electrode yakakwira-frequency mafungu mune yebasa, yakakodzera kuenderera kwenguva refu musono seam welded pombi uye spiral lap seam welding, boiler chubhu uye fin heat exchanger spiral welded fin, yekunze dhayamita. pombi inogona kuva 1200 mm uye kukora kwemadziro 16 mm, ventral beam welding electrode ukobvu 9.5 mm, kubereka kwakanyanya.
② yakakwira-frequency induction welding: diki dhayamita chubhu uye ukobvu hwemadziro echishandiso neiyo induction yekudziya coil inogona kusungirirwa kune dhayamita yekunze ye9 mm uye 1 mm yakatetepa-yakavezwa chubhu. Inowanzo shandiswa mudiki dhayamita longitudinal pombi seam welding uye ndarira inogona zvakare kushandiswa girth weld, asi mashandisirwo emagetsi akakura pane yakakwirira-frequency kuramba welding. Iwo makuru ma paramita anobata iyo yakakwirira-frequency welding mhando ndeye yakakwira-frequency simba frequency, simba, workpiece kugadzira angle, welding kumhanya uye kudzvanywa kubva pakusvinwa, iyo electrode (kana induction coil) uye kusvina rollers. Yakakura midziyo frequency simba rekupa, iyo workpiece yekugadzira zvishandiso uye extrusion muchina. Yakagadzikana yakakwirira-frequency welding mhando, kugadzirwa kwepamusoro uye mutengo wakaderera. Yepamusoro-inoshanda otomatiki yekugadzira mutsara, kugadzirwa kweyepamusoro nzira slit chubhu.
