Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
Izvo zvinhu zvinokanganisa kugadzikana kwewelding arc zvinonyanya zvinosanganisira zvinotevera zvinhu:
(1) Welder hunyanzvi hwekushandisa uye otomatiki arc kureba kugadzirisa kugona
Iyo welder's operating technique chinhu chakakosha pakuona arc kugadzikana. Munguva chaiyo yewelding process, pfuti yewelder (strip) gestures inofanirwa kuve yakakodzera uye kureba kwearc kunofanirwa kuchengetwa nguva dzose sezvinobvira. Zvikasadaro, welding ikozvino kushanduka kana kunyangwe kukanganiswa kwearc kuchaitika. The kona pakati nomoto waya uye workpiece, uye pakati nomoto pfuti uye workpiece, anofanira kuva akakodzera kubudisa zvakakodzera kupinda, kudzivirira nomoto kuremara, uye kuchengetedza yakanyungudutswa dziva. Kune otomatiki welding, kureba kwearc kunoda kugadziridzwa otomatiki kuti ive nechokwadi chekuti arc kureba kunoramba kuripo panguva yewelding process, nekudaro kuve nechokwadi chenguva dzose welding paramita.
(2)Arc welding simba rekupa
① Mhando dzearc welding magetsi masosi: DC arc welding magetsi masosi uye square wave AC arc welding magetsi masosi ane nani arc kugadzikana pane sine wave AC arc welding magetsi masosi. Kugadzikana kwe pulse arc welding power supply iri nani, saka, pulse arc welding power supply inowanzo shandiswa kana welding ine diki ikozvino.
②Zvinhu zvekunze zvearc welding simba rekupa Mamiriro ekunze emagetsi emagetsi anofanirwa kuenderana nearc yakagadzikana yekupisa zvinodiwa zveiyo inoenderana welding nzira. Gasi simbi arc welding inowanzo shandisa waya yakatetepa (iyo dhayamita yewaya haina kukura kupfuura 3.2mm), uye inononoka-inodzika yekunze hunhu simba rekupa rinoda kusarudzwa, zvikasadaro welding Gasi simbi arc welding ine isina kugadzikana arc uye yakakwira ikozvino dzimwe nguva. inoshandisawo waya gobvu. Paunenge uchishandisa waya gobvu, zvinodikanwa kushandisa sosi yemagetsi ine mawere anodonha ekunze maitiro.
③Masimba emagetsi emagetsi anosanganisira shanduko yenguva pfupi. Iyo CO2 welding arc nguva nenguva ichipisa nekudzima. Izvi zvinoda kuti hapana-mutoro voltage yemagetsi kuti isimuke nekukurumidza uye pfupi-circuit ikozvino kuti isimuke zvine mwero.
④Iyo isina-mutoro voltage yearc welding magetsi. Iyo yakakwirira iyo isina-mutoro voltage yearc welding magetsi, zviri nyore kutanga arc uye zvirinani kugadzikana kwekupisa kwearc. Nekudaro, kana iyo isina-mutoro voltage yakawandisa, zvinokanganisa kuchengetedzeka kwemunhu we welder.
(3) Welding ikozvino
Iyo yakakura iyo welding ikozvino, iyo yakakwirira tembiricha yearc, iyo yakasimba dhigirii yeionization gasi uye kupisa kuburitsa munzvimbo yearc column, uye zvakanyanya kugadzikana kupisa kwearc kuchave.
(4) Arc voltage
Iyo arc voltage inofanirwa kunyatsoenderana neyazvino welding. Sezvo iyo welding ikozvino inowedzera, iyo arc voltage inofanira kuwedzera. Kana iyo welding ikozvino inogara iripo, kana iyo arc voltage iri diki, zviri nyore kukonzera pfupi pfupi; kana iyo arc voltage yakakura kwazvo, iyo arc ichazununguka zvine chisimba uye inoparadza kugadzikana kweiyo welding arc.
(5) Workpiece pamusoro mamiriro, kuyerera kwemhepo uye magineti kutsauka
Kana iyo yepamusoro ye workpiece isina kuchena, yakadai semafuta, ngura, unyoro, nezvimwewo, arc ignition uye arc inopisa ichave isina kugadzikana. Kana iyo inodzivirira mhepo inoyerera isina kugadzikana kana kune magineti deflection, iyo arc ichavawo isina kugadzikana.
