MIG Welding - masinya

Zokushisela - kuba inqubo engenakuqhathaniswa ngokuvumela kakhulu enokwethenjelwa futhi ngokunembile enze unomphela uxhumano izingxenye noma izingxenye izihloko esenziwe ngezinto ezihlukahlukene. Kuze kube manje, bethuthuka futhi ukusebenza ukukhiqizwa izindlela eziningi lahlukene lasetjentiswako Welding Fusion. Ngamunye izindlela has ngebuhle nebubi.

Omunye ethandwa kakhulu Welding ubuchwepheshe kuyinto Welding semi-automatic ezihlukahlukene zokuzivikela igesi eziphindwe. It uyakwazi ukwenza ngisho ochwepheshe abaneziqu ngaphansana kwadingeka kwezinhlelo imanuwali arc Welding. Kulokhu, inqubo ithatha isikhathi esincane. I kwaphumela weld kuncike ubuchwepheshe isezingeni eliphakeme futhi ayidingi bula okwalandela kusukela slag. Ukuhlelwa (primer, upende, njll) ashiselwe imikhiqizo zingenziwa ngaphandle kokulibala ngokungadingekile. Ukusetshenziswa semi-automatic Fusion Welding ivumela yokuxhuma mncane kakhulu ucezu metal (0.1 - 1.5 mm), enze yokuxhuma umphetho kanye ezivuzayo curvilinear, amalunga ukusingatha ngokwezinga elincane. Kuyinto enhle Welding inqubo yabadobi noma ekukhiqizweni.

Igama elithi "semiautomatic" Lokhu ubuchwepheshe ikakhulukazi wire. Eqinisweni, kungcono arc efanayo Welding ekhethekile wire electrode owenziwa e igesi engaxubani namakhemikhali. Isimiso ku ogxile Welding semi-automatic, ulula. Element yokudla Welding wire ikhiqizwa a idivaysi eyamukelayo, bese - ezonini weld. idivayisi ekhethekile ukulawula apharathasi ukhonza ukulawula ijubane wire electrode.

Ukuqala umzimba ukusebenza kuhlanganisa okhiye kanyekanye nalokho ukulethwa igesi kanye wire. Ngaphambi ekuqaleni inqubo isikhala okuhloswe weld umphetho ligcwele yokucucuza ka indlu ekhethekile. Excitation wenziwa arc ngokuhambisa ekuqhubekeleni phambili kwezindaba electrode eduze ashiselwe imiphetho evele lapho iphimbo electrode ifakiwe, noma uma isivele ixhunywe feed bese ecucuza egcwele. Ngemva kwalokho siba ungqongqoze electrode ithiphu eqina slag, uma arc luqede luvutha waphinda. Le nqubo ibizwa ajwayele kushintshana zamanje, nakuba kungenzeka ukusebenzisa unomphela.

MIG Welding - inqubo kancane ezenzakalelayo. Ukuhambisa umnikazi eduze UWelder umphetho senziwa ngesandla, kunoma iyiphi isisindo nge kugcizelelwe ukuzikhohlisa ekhethekile ibekwe phezu umkhiqizo. Isetshenziswa njengesici esebenza ngogesi ephathekayo futhi umile, ukukhetha kuncike umsebenzi othize Welding. I electrode Abazinikele bakhethwa ngendlela izakhiwo metal ashiselwe nezici weld ukutholwa. Le gesi avikele, lapho Welding Kwenziwa lulwimi futhi ekhethiwe esekelwe izakhiwo steel ashiselwe. Ukuze ongaphakeme carbon steel avikele igesi kudala carbon dioxide (CO _2), argon zingasetshenziswa. Negesi ihlinzekwa kusuka umlomo wombhobho, displacing emoyeni kusukela endaweni Welding nasekuvikeleni umphetho.

Ngokuthenga imishini Welding, abathengi abaningi bafuna ukwazi ukukhiqiza futhi Welding aluminium. Ngenxa ubunjalo metal, Welding semi-automatic aluminiyamu kuyinto nezobuchwepheshe unezinselele ezinzima kunalezo enkompolo imikhiqizo steel. Ubunzima elihlobene ne umehluko enkulu lokushisa ukuncibilika aluminium (660 ° C) kanye ifilimu zokuzivikela ku ubuso bayo (2200 ° C). Thola Ukungena izinga weld kanye omuhle semi-automatic endaweni argon kungenzeka, kodwa lapha konke kuzoncika amakhono, ubuciko kanye nekhono of the UWelder kokwenza umsebenzi.
