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,日本的造船业开始使用药皮焊条.自此,日本的弧焊技术取得了长足进步.弧焊技术的历史是焊接工艺"高速度、高效率"的历史.自药皮焊条开始焊接材料已发展成为更高效的埋弧焊焊材和气保焊焊材,并能更容易地结合自动化焊接和机器人焊接.气保焊焊材主要分为实芯焊丝和药芯焊丝,药芯焊丝的应用因其出色的实用性和效率而逐年增加.介绍了药芯焊丝作为主要焊材的发展趋势,尤其是在碳钢焊接上的应用
