Arc welding technologies in japan have been advanced steadily since the time when an application of covered electrodes was first examined in the shipbuilding industry about 90 years ago. the history of the arc welding technology has always been the history of the pursuit of higher " efficiency and speed " of welding processes welding materials, originally started with covered electrodes ， have been developed into more efficient submerged arc welding materials and gas ? shielded arc welding materials with which automatic welding and robotic welding can easily be conducted. the gas ? shielded arc welding materials can be classified mainly into solid wires and flux ? cored wires ( fcws ), and of these wires ， fcw has been increasing in uses year by year because of its excellent workability and efficiency. this article describes the recent trends in the development of fcws which now hold the major position in the welding materials. a special focus is put on the fcws for carbon steels
90年前，日本的造船業開始使用藥皮焊條.自此，日本的弧焊技術取得了長足進步.弧焊技術的歷史是焊接工藝"高速度、高效率"的歷史.自藥皮焊條開始焊接材料已發展成為更高效的埋弧焊焊材和氣保焊焊材，並能更容易地結合自動化焊接和機器人焊接.氣保焊焊材主要分為實芯焊絲和藥芯焊絲，藥芯焊絲的應用因其出色的實用性和效率而逐年增加.介紹了藥芯焊絲作為主要焊材的發展趨勢，尤其是在碳鋼焊接上的應用
