摘要： A base material is welded by a first welding method in a case where a welding parameter related to heat input to the base material is less than a first threshold value. The base material is welded by a second welding method in a case where the welding parameter is less than a second threshold value and is more than the first threshold value. The base material is welded by a third welding method in a case where the welding parameter is more than the second threshold value. By adjusting welding conditions regardless of the thickness of the base material, a welding method suitable for the thickness of the base material is determined to provide a welding with little spatter and no meltdown of the base material.

摘要： A method and apparatus for providing short arc welding-type power is disclosed. The system includes a power supply, a wire feeder, and a controller. The output current is decreased at dive rate when the arc forms. The dive rate is maintained until the currents drops to a threshold, preferably a function of the peak short current in that cycle. Then the current is held steady for a length of time that is a percentage of the short time for that cycle. Then the current is decreased at the normal rate until the short reforms, and the current begins increasing at the normal rate. The holding steady portion can be omitted.

摘要： A real-time virtual reality welding system including a programmable processor-based subsystem, a spatial tracker operatively connected to the programmable processor-based subsystem, at least one mock welding tool capable of being spatially tracked by the spatial tracker, and at least one display device operatively connected to the programmable processor-based subsystem. The system is capable of simulating, in virtual reality space, a weld puddle having real-time molten metal fluidity and heat dissipation characteristics. The system is further capable of importing data into the virtual reality welding system and analyzing the data to characterize a student welder's progress and to provide training.

摘要： A method is performed in a welding or cutting system, including a power supply to deliver a current through a weld circuit to a welding torch to create an arc. The method includes: measuring the current to produce a measured current; measuring a voltage on a sense point of the power supply or the weld circuit that is spaced from the welding torch, to produce a measured voltage that differs from the arc voltage by a voltage drop caused by the current and inductance of the weld circuit; compensating the measured voltage for the voltage drop using the measured current and an inductance value, to produce a compensated voltage; computing a derivative of the compensated voltage; computing a second derivative of the measured current; and upon determining the inductance value and the inductance differ based on the derivative and the second derivative, adjusting the inductance.

摘要： A method comprises: providing a welding current pulse through a welding circuit to create an arc for a welding operation; measuring an arc voltage to produce a measured arc voltage pulse that includes an inductive voltage drop due to inductance in the welding circuit and current ramps of the welding current pulse; and during the welding operation, implementing an inductance-compensation feedback loop. The feedback loop includes canceling the inductive voltage drop from the measured arc voltage pulse using a canceling voltage to produce a compensated arc voltage pulse; and deriving the canceling voltage based on the compensated arc voltage pulse.

摘要： A method is provided for controlling arc welding including forward and reverse feeding periods alternately switched. By the method, a set of a short circuit period and an arc period is repeated, and the arc welding is controlled such that the reverse feeding period shifts to the forward feeding period when an arc occurs during the reverse feeding period, and that the forward feeding period shifts to the reverse feeding period when a short circuit occurs between the welding wire and the object during the forward feeding period. The reverse feeding period includes a reverse feeding deceleration period having a time length that is adjusted in accordance with the time length of the short circuit period.

摘要： Systems and methods for selecting a welding output waveform based on characterizing a welding circuit output path with respect to its electrical characteristics. At least one electrical characteristic (e.g., inductance, resistance) of a welding output circuit path connected to a welding power source is determined. A welding output waveform is selected from a plurality of welding output waveforms based on the determined electrical characteristics. As a result, the selected welding output waveform is matched to the welding output circuit path electrical characteristics to provide superior welding performance.

摘要： A three stage power source for an electric arc welding process comprising an input stage having an AC input and a first DC output signal; a second stage in the form of an unregulated DC to DC converter having an input connected to the first DC output signal and converts the first DC output signal to a second DC output signal of the second stage; and a third stage to convert the second DC output signal to a welding output for welding wherein the input stage and the second stage are assembled into a first module within a first housing structure and the third stage is assembled into a second module having a separate housing structure connectable to the first module with long power cables. The second module also includes wire feeding systems and electronics.
