Welding busur nuduhake energi panas sumber busur, supaya workpiece kanggo sekring bebarengan kanggo entuk cara co-welding ora langsung atom.Arc welding minangka cara welding sing paling akeh digunakake.

Miturut statistik nomer negara industri, welding busur ing welding saka total produksi ing babagan umume ndhuwur 60%.

Sambungan las busur, nganggo utawa tanpa logam pengisi.Nalika elektroda digunakake kanggo proses welding, kabel molten, disebut MIG busur welding, kayata SMAW, submerged busur welding, gas shielded nglindhungi welding, tubular kabel busur welding;karo elektroda welding dhasar kanggo proses welding karbida utawa rod tungsten ora nyawiji, disebut MIG busur welding, kayata gas tungsten busur welding, plasma arc welding.

Gumantung ing karakteristik proses, welding busur bisa dipérang dadi welding busur elektroda, welding busur submerged, welding busur gas shielded lan plasma arc welding lan ing.

Klasifikasi arc welding
Arc gandheng bisa dipérang dadi telung jinis manual logam busur welding, submerged busur welding lan gas shielded busur welding.Kauntungan paling gedhe saka peralatan welding tangan-otomatis iku prasaja, fleksibel, trep, lan ditrapake kanggo sawetara saka sudhut welding macem-macem posisi welding lan girth jahitan terus lan macem-macem kurva welding.Utamané cocok kanggo operasi wusana padha lan welding welding singkat;welding busur submerged otomatis kanthi produktivitas dhuwur, kualitas weld apik, lan kahanan kerja sing apik;welding busar shielded gas duwe efek protèktif, busur stabil, panas klempakan.
