A mobile welding system that does not rely exclusively on a track to define the path of the welder. One embodiment includes a mobile welder adapted to move along a work piece. The mobile welder includes a chassis, including a welding implement, and a travel assembly configured to support the chassis over a portion of the work piece. The mobile welder also includes a motor assembly configured to selectively cause the chassis to move relative to the work piece. The mobile welder further includes a chassis holder, having a magnet assembly, configured to provide a force holding the chassis a selected distance from the work piece. The magnet assembly includes a magnet rotatably mounted between a ferrous material and a non-ferrous material to selectively control application of a magnetic field toward the work piece.

Mobile welding system

A mobile welding system that does not rely exclusively on a track to define the path of the welder. The present invention generally provides a mobile welder adapted to move along a work piece, the mobile welder including a chassis supporting a motor assembly; a travel assembly attached to the chassis and adapted to support the chassis over a portion of the work piece, wherein the motor is coupled to the travel assembly to selectively cause the chassis to move relative to the work piece; a controller connected to the motor assembly to control movement of the chassis relative to the work piece; a chassis holder connected to the chassis, the chassis holder being adapted to provide a force holding the chassis a selected distance from the work piece; and a welder supported on the chassis, the welder including an implement adapted to perform a welding operation, wherein the implement is supported on the chassis at a location where the implement and the chassis define an uninterrupted line of sight from the implement to the work piece, wherein the chassis holder is spaced from the line of sight a distance sufficient to prevent the chassis holder from interfering with the welding operation.

A welding system and method is provided for welding heavy plate, where the method and device include using a laser which directs a beam to a first weld puddle to weld at least a portion of a work piece and a welding torch to direct a first welding electrode to the first weld puddle while the beam is being directed to the weld puddle. The welding torch deposits the first welding electrode to create a first weld bead. A flux nozzle is employed to deposit a welding flux onto the weld bead, and a submerged arc welding torch is used to direct a submerged arc filler metal to the weld bead to create a second weld bead through a submerged arc welding process, where the submerged arc welding process melts a portion of the first weld bead to consume the melted portion into the second weld bead.

Method and apparatus for heavy plate joining with hybrid laser and submerged-arc welding process

The invention described herein generally pertains to a system and method for detecting a moisture with a flux used in a welding process. A sensor is employed with a flux source that supplies a welding operation or process in which the sensor detects a moisture level with a flux within the flux source. A monitor component is configured to receive or aggregate data from the sensor, wherein the data relates to the moisture level associated with a flux supply or a portion of flux.

Flux moisture control for sub-arc welding process

In a hard facing process, a core material is applied to the base material of an article, which may incorporate metal components. An additive is introduced into a molten puddle generated by the hard facing process. The additive functions to increase the wear resistant capabilities of the hard faced article. In one embodiment, the additive comprises mineral particulates, which may consist of diamond granules.
