…After that, the use of welding gradually increased through a period of improvement. As its use increased, a more efficient welding method was desired, and from around 1930, submerged arc welding and inert gas arc welding, which welds in a protective gas atmosphere, were invented and came into use around World War II. The development of new welding methods in the last 30 years has been remarkable, with electroslag, carbon dioxide arc, friction, electron beam, ultrasonic, diffusion, plasma and laser welding being invented one after another and coming into practical use. … *Some of the terminology that refers to "inert gas arc welding" is listed below.

…その後,漸次,改良の時代を経て溶接の利用度は増加していった。利用度が増大するに伴い,高能率の溶接方法の出現が望まれるようになり,1930年ころよりサブマージアーク溶接法,保護ガスの雰囲気中で溶接を行うイナートガスアーク溶接法などが考案され,第2次世界大戦のころから利用されるようになった。最近の30年間の新しい溶接法の開発はめざましく,エレクトロスラグ・炭酸ガスアーク・摩擦・電子ビーム・超音波・拡散・プラズマおよびレーザー溶接などが次々に発明され実用されるようになってきた。… ※「イナートガスアーク溶接」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
