A welding or additive manufacturing wire drive system includes a first spindle for a first welding wire spool, a second spindle for a second welding wire spool, a first drive roll, and a second drive roll. One or both of the drive rolls has a circumferential groove. A first welding wire and a second welding wire are located between the first drive roll and the second drive roll in the circumferential groove. The first welding wire contacts the second welding wire between the first drive roll and the second drive roll. The first welding wire further contacts a first sidewall portion of the circumferential groove. The second welding wire further contacts a second sidewall portion of the circumferential groove. Both of the first welding wire and the second welding wire are radially offset from a central portion of the circumferential groove.

Present embodiments include systems and methods for stick welding applications. In certain embodiments, simulation stick welding electrode holders may include stick electrode retraction assemblies configured to mechanically retract a simulation stick electrode toward the stick electrode retraction assembly to simulate consumption of the simulation stick electrode during a simulated stick welding process. In addition, in certain embodiments, stick welding electrode holders may include various input and output elements that enable, for example, control inputs to be input via the stick welding electrode holders, and operational statuses to be output via the stick welding electrode holders. Furthermore, in certain embodiments, a welding training system interface may be used to facilitate communication and cooperation of various stick welding electrode holders with a welding training system.

The present invention discloses a method for welding FeAl intermetallic compound microporous material and a welded part made thereby, and the present invention relates to the field of welding technology. For the problem in the prior art that there is great difficulty in welding between FeAl microporous material and dense stainless steel, the method for welding FeAl intermetallic compound microporous material, in accordance with the present invention, comprises the following steps: turning on welding torch fuel-gas of a fusion-welding machine, and turning on welding shielding gas in a shield; adjusting welding parameters of the welding machine and parameter of the welding shielding gas in the shield for a fusion welding process; switching on the welding machine, and using welding wire as welding filler for welding FeAl intermetallic compound microporous material to dense stainless steel; and, cooling after completion of the welding.

A welding system configured to calibrate a welding torch's orientation without using a magnetometer.

A quick release mounting assembly or connector assembly for connecting a wire feeder to a robotic welding system is disclosed. The connector assembly includes an adapter plate configured to mount to a robotic welder of the robotic welding system, a feeder plate configured to couple to a wire feeder of the robotic welding system, and a clamping plate mounted to the adapter plate and configured to clamp the feeder plate to the adapter plate. The feeder plate can be positioned and clamped in place by the clamping plate when the clamping plate is at least partially disposed within a clamping zone.

A machine learning device which learns to determine at least one arc welding condition includes a state observation unit which observes a state variable consisting of at least one physical quantity regarding the arc welding and the at least one arc welding condition at least during or after the arc welding, and a learning unit which learns a change in the at least one physical quantity observed by the state observation unit and the at least one arc welding condition in association with each other.

A handle assembly includes a housing and an interchangeable saddle for customizing a geometrical grip of the handle. In one form, the housing includes an attachment feature and the interchangeable saddle includes a mating attachment feature to allow for the interchangeable saddle to be removably secured to an upper surface of the housing. Each interchangeable saddle defines a customized geometrical grip.

A self-adjusting wire feeder mounting assembly includes a mount fixedly connectable to a multi-axis robotic arm, and a slidable, floating adapter plate for mounting of a wire feeder thereon. The adapter plate is coupled with and slidable about the mount, and the adapter plate is moveable relative to the mount when a force is applied to the wire feeder.

A wire feeding system includes a first feeder provided with a first feeding motor that feeds a wire in a wire feeding direction, a second feeder spaced apart from the first feeder in the wire feeding direction and provided with a second feeding motor that feeds the wire in the wire feeding direction, and a controller that controls the rotation speed of the first feeding motor based on a first speed command and controls the rotation speed of the second feeding motor based on a second speed command. The controller gradually changes the second speed command over time when an amount of change of the second speed command is not within a predetermined range.
