摘要： Disclosed is a welding system configured to perform additive manufacturing, particularly a welding system to achieve a stable a laser metal deposition with hot wire process by controlling the contact point between the welding wire and the workpiece. For example, the resistance of the stick-out wire is measured and the measured resistance is converted to a distance signal, which can then be used for comparison to a desired distance. The distance between the contact tip and the workpiece can then be adjusted based on the comparison. The present disclosure also relates to using a constant enthalpy system to determine and control the contact tip to workpiece distance.

摘要： A welding-type system (100) includes a power supply (128) configured to control preheating of an electrode wire (138). A controller (102) is configured to receive a plurality of power values corresponding to a power output of the power supply (128) and calculate an arc power value corresponding to an arc condition at the preheated electrode wire (138) based on a rate of change of the plurality of power values. A target power output value is determined based on the calculated arc power value, and the power output is adjusted based on the determined target power value. A method based on the same principles is also defined.

摘要： A laser processing head includes first (116) and second (118) contact points connected to a power source. The power source generates a current to flow through an electrode wire (112) between the first and second contact points to heat the electrode wire. A laser source generates one or more laser beams (108A, 108B) having lasing power sufficient to at least partially melt the electrode wire. A coaxial laser head focuses the one or more laser beams at one or more focal points (110) on a workpiece (114) to at least partially melt the electrode wire.

摘要： Systems and methods of a laser welding device are disclosed. The laser welding device includes a laser generator (102) configured to generate welding-type lasing power. A lens (104) focuses the welding-type lasing power at a focal point on a workpiece to generate a puddle during a welding-type operation. A wire feeder (123) is configured to feed wire to the puddle generated by the laser generator. A laser scanner (106) controls the lens to move the focal point of the welding-type lasing power in multiple dimensions over the workpiece during the welding-type operation. In some examples, the feed wire is used in an additive manufacturing process.
