3. Khase e sirelelitsoeng welding e ka aroloa ka tjheseletsa e sirelelitsoeng ka khase e sa sebetseng (TIG welding), welding e sebetsang ka khase e sirelelitsoeng (welding ea MAG) .Ho hlakile hore argon e sebelisoa hangata ka lebaka la theko ea eona e tlase, ka hona, welding ea tšepe e sirelelitsoeng ka khase ea inert e boetse e tsejoa e le argon arc welding.Tungsten inert gas welding ke ts'ebetso ea welding eo ho eona tungsten kapa alloy ea tungsten e sebelisoang e le lisebelisoa tsa elektrode, 'me arc e hlahisoang lipakeng tsa elektrode le thepa ea motheo e sebelisetsoa ho qhibilihisa thepa ea motheo le ho tlatsa terata tlas'a tšireletso ea khase ea inert. .

DC TIG welding e nka mohloli oa matla oa ho tjheseletsa oa DC arc e le mohloli oa matla a ho cheselletsa, o nang le matla a mabe haholo le lisebelisoa tse ntle.E sebelisoa haholo-holo bakeng sa ho tjheseletsa tšepe e sa hloekang, titanium, koporo le alloy ea koporo.Mohloli oa matla oa ho tjheseletsa oa AC TIG o tsoa ho AC arc, 'me anode le cathode ea lisebelisoa tsa motheo li fetohile.EP polarity electrode overheating e ka tlosa lera la oxide e tlase, e sebelisoang haholo bakeng sa aluminium, magnesium le welding e 'ngoe ea alloy.
Ha TIG (GTAW) ts'ebetso ea ho tjheseletsa, welder e ka ba sethunya sa welding ka letsohong le le leng le terata ea ho tjheseletsa ka letsoho, e loketseng bakeng sa ts'ebetso e nyenyane le ho lokisoa ha letsoho.TIG e ka chesetsoa hoo e ka bang litšepe tsohle tsa indasteri, e fana ka sebopeho se setle sa welding, slag e nyane le lerōle li ka sebelisoa haholo ka poleiti ea tšepe e tšesaane le e teteaneng.
MAG (Metal Active Gas) Welding e sebelisa CO₂ kapa motsoako oa argon le CO₂ kapa oksijene (Ac Active Gas).Ka linako tse ling welding ea CO₂ e bitsoa CO₂ arc welding.Lisebelisoa tsa ho tjheseletsa tsa MIG le MAG li tšoana ka hore li ka fepeloa ka ntle ho toche ka mochini o fepelang oa mohala o ikemetseng 'me li loketse bakeng sa welding ea othomathike, re sa bue ka welding ka letsoho.Phapang e kholo pakeng tsa bona e lutse ka khase e sireletsang, ea pele e sirelelitsoe ka kakaretso ke khase e hloekileng ea argon, e loketseng bakeng sa ho cheselletsa litšepe tse se nang ferrous;MAG tjheseletsa haholo-holo e sebelisa CO₂ khase, kapa argon e tsoakiloeng CO₂ khase e sebetsang, e leng Ar+2%O₂ kapa Ar+5%CO₂, e loketseng bakeng sa ho cheselletsa tšepe e matla haholo le tšepe e phahameng ea alloy.E le ho ntlafatsa ts'ebetso ea ts'ebetso ea CO₂welding, CO₂+Ar kapa CO₂+Ar+O₂ e tsoakiloeng ea khase kapa terata ea flux-cored e ka boela ea sebelisoa.MAG welding e khetholloa ka lebelo la eona la ho tjheseletsa ka potlako, ts'ebetso e phahameng ea ho qalisa arc, letamo le tebileng, ts'ebetso e phahameng ea deposition, ponahalo e ntle, ts'ebetso e bonolo, e loketseng ho chesehela ka lebelo le phahameng la pulse MIG (GMAW).
Fast e ikemiselitse ho R&D le tlhahiso eali-cylinders tsa hydraulicle litsamaiso tsa haeteroliki, ho sebeletsa bareki le ho fa basebetsi bophelo bo betere.Ho fihlela joale, re se re thusitse bareki ba likete lefats'eng lohle ho fana ka boiphihlelo ba hydraulic cylinder le moralo oa sistimi ka melemo ea tlholisano.
