摘要： PROBLEM TO BE SOLVED: To provide a welding method and a welding apparatus for controlling an arc in high speed response. SOLUTION: In the welding method and apparatus, the output is preferably an periodic CV (Voltage Controlled) MIG (Metal Inert Gas) output, and each cycle is divided into a plurality of segments. The output parameters are sampled a plurality of times in the inside of the one or more segments. The CV output is controlled in the inside of at least one segment so as to respond to the above sampling. In various implementations, the parameters are output power, load resistance, output current, output voltage or their functions. The control loop is preferably a PI (Proportional and Integral) loop or an PID (Proportional Integral and Differential) loop. The loop can be added only in the insides of windows. The set point may be commanded, or may be fixed. The system can be used for welding having a controlled arc length. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To prevent the forming of a ball with a large diameter at stopping welding.SOLUTION: The output current is commanded to a level sufficient to clear a short circuit if a short circuit forms when the process is stopping (212). A low current level is commanded after the short circuit has cleared (216). The low current level is sufficiently low to prevent the forming of a large ball. This is repeated until a short circuit does not form. The wire feed speed is monitored, and the stopping process begins when the wire feed speed drops below a threshold. The stopping process is performed with an MIG process, a pulsed spray process, and a short circuit transfer welding process. The arc voltage is monitored to determine the status of the arc. The motor is commanded to stop in response to receiving a user provided stop command, and the braking of the motor is controlled. At least one output parameter may be reduced before the threshold is reached, but after receiving the stop signal.

摘要： PROBLEM TO BE SOLVED: To prevent a formation of a large ball by controlling a current corresponding to the short circuit formation, at the first level sufficient to clear a short circuit, then at a low level when the short circuit is cleared, and by repeating these steps until the short circuit formation does not take place. SOLUTION: A micro processor 808 stops a motor, upon receipt of a stop signal, by using a publicly known wire feed motor speed instruction signal, outputs a low constant voltage instruction, and maintains an arc for a period that the feed speed is reduced until it reaches a given feed speed. A control means 807 monitors an arc voltage and instructs a current buildup when the short circuit is detected. When the arc voltage reaches a threshold limit value, which is based on welding data, and shows a generation of the short circuit, the current buildup instruction is ceased and an extremely low current is instructed. When the short circuit is generated because the wire is kept to be fed and contacts with a paddle or the paddle is backflown and touches with the wire, routine is repeated and the large ball is not formed at the end of the wire.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for MIG welding using an AC power source to obtain a high deposition rate. SOLUTION: When in an AC mode, the output is unbalanced, or the balance may be controlled. The balance may be controlled to provide a desired deposition rate and/or to obtain a desired dilution. The frequency may be any frequency, for example, 30 Hz, 60 Hz, 90 Hz, or more. The weld path may have groove with angle of less than 50 degrees. A consumable cored wire may be used, and provide at rates of 13.6 kg or 15.9 kg per hour using a single arc. In various embodiments, the balance may have a negative portion of at least 1.5 times the positive portion. The process may be started using an extended negative portion, for example, 0.5 or 0.75 second. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To prevent agglutination of a wire to a weld joining part when the arc welding is finished. SOLUTION: A wire supplier 801 supplies a wire 802 to a welding article 803 of a work 806 via a welding torch 804. An arc voltage is used to determine if a desired arc length exists and to adjust a long term command as well. An electric current command at every short circuit is led out from a real time arc current, and a welding speed is controlled by adjusting the electric current command instantaneously or at every short circuit. A point of time when a short circuit is going to be eliminated is detected at real time by using a function obtained by subtracting the time differentiation from the arc current time differentiation. A stop algorithm is used to monitor the arc at every short circuit. When the arc welding is finished, an ultra low current level is supplied to avoid a formation of a ball. When a short circuit takes place after the low current level, an outbreak energy is supplied to solve the short circuit and, once the short circuit is solved, the ultra low current is supplied again to avoid forming of a large size ball.

摘要： A method and apparatus for stopping a welding process includes monitoring the status of the arc. The output current is commanded to a level sufficient to clear a short if a short circuit forms when the process is stopping. A low current level is commanded after the short has cleared. The low current level is sufficiently low to prevent the forming of a large ball. This is repeated until a short does not form. The wire feed speed is monitored, and the stopping process begins when the wire feed speed drops below a threshold. The stopping process is performed with, a MIG process, a pulsed spray process, and a short circuit transfer welding process. The arc voltage is monitored to determine the status of the arc. The motor is commanded to stop in response to receiving a user provided stop command, and the braking of the motor is controlled. At least one output parameter may be reduced before the threshold is reached, but after receiving the stop signal in another alternative embodiment.

摘要： A short circuit arc welding system has a control scheme uses a current command signal to drive the output current. The command signal is comprised of a long-term current command that sets the long-term current command level and a real time or short-by-short current command. Arc voltage feedback is led to determine if the desired arc length is present and to adjust the long-term command. The short-by-short current command , derived from real-time arc current feedback and is used to control the burn-off rate by an instantaneous, or short-by-short, adjustment of the current command. A function of the time derivative of arc power, less the time derivative of arc current, is used to detect, in real time, when the short is about to clear. A stop algorithm is employed that monitors the arc on a short-by-short basis. When the process is ending a very low current level is provided to avoid forming a ball. However, if a short is created, Qreq after the low current level, a burst of energy is provided to clear or burn off the short. After the short is cleared, very low current is again provided to avoid forming a large ball. This is repeated until the wire stops and the process ends.
