摘要： In consumable electrode type gas shielded arc welding, a time second order differential value of a welding voltage or an arc resistance is calculated. Based on the second order differential value, a detachment of a droplet or a timing just before the detachment is detected. After the droplet detachment or the timing just before the detachment is detected, a welding current value is immediately switched to a predetermined current value lower than that at the time of the detection. According to the control, even if welding conditions are changed or wire extension lengths are changed in the welding, the droplet detachment can be correctly detected.

摘要： Disclosed is a method for performing gas-shielded pulsed arc welding at high current densities with a flux-cored wire as an electrode wire. The pulsed arc welding is carried out by passing a pulsed current so that a pulse peak current density during a pulse peak time Tp is 400 to 950 A/mm2, a pulse base current density during a pulse base time Tb is 200 A/mm2 or more and differs from the pulse peak current density by 200 to 400 A/mm2, and an average current density is 350 to 750 A/mm2. The method allows significant spatter reduction while attaining a high deposition rate.

摘要： In consumable-electrode gas-shield arc welding, carbon dioxide gas is used as shield gas; the molten pool is formed using a pulsed arc as a leading electrode arc transferring one droplet per cycle by alternately outputting, in each cycle, pulses of two different pulse waveforms of which a pulse peak current level and/or a pulse width per period differ; the conductively heated filler wire is inserted into the molten pool as a trailing electrode; the distance between a tip of the filler wire inserted into the molten pool and a conductive point of the filler wire is set within a range of 200×10−3 to 500×10−3 m; and a leading-electrode base current value is set larger than a trailing-electrode filler current value. According to such a method, even when inexpensive carbon dioxide gas is used as shield gas, the amount of spatter can be reduced, and high weldability can be achieved in multipass welding.
