automatic weld वाक्य

This controller is based on single - chip microcomputer at89c51 , and it can realize automatic welding , line voltage compensation , welding current and voltage display through the combining of constant current and voltage supply control with varied sets of standard parameter storages , fault self - diagnostic programs and system self - protection ability
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
