The system comprises a hybrid robot system composed of a mobile robot and an MDOF robot, a 3D vision system, and a welding system used for welding. The rough positioning technique based on a mobile platform and the accurate recognition and positioning technique based on high-accuracy 3D vision are combined, so the working range of the MDOF robot in the XYZ directions is expanded, and flexible welding of large structural parts is realized. The invention adopts 3D vision, thus having better error tolerance and lower requirements for the machining accuracy of workpieces, positioning accuracy of mobile robots and placement accuracy of the workpieces; and the cost is reduced, the flexibility is improved, the working range is expanded, labor is saved, production efficiency is improved, and welding quality is improved.

In certain embodiments, inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head may be adapted specifically for this purpose, and may include one or more coils to direct and place the inductive energy, protective structures, and so forth. Productivity of a welding process may be improved by the application of heat from the induction heating head. The heating is in addition to heat from a welding arc, and may facilitate application of welding wire electrode materials into narrow grooves and gaps, as well as make the processes more amenable to the use of certain compositions of welding wire, shielding gasses, flux materials, and so forth. In addition, distortion and stresses are reduced by the application of the induction heating energy in addition to the welding arc source.

A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.

Control method of a welding device having an upper tool, lower tool, control unit and welding device positioning arrangement for a drive system having no or little mechanical losses. In the method, the lower and upper tools are moved relative to each other, the drive system of the positioning arrangement presses first and second components against each other and, during the actuating of the drive system, a force is measured at a static first section (and/or a position of a movable second section of the positioning arrangement relative to the static first section). The measured force and/or position is compared with a predetermined force and/or position, and actuating is stopped after the predetermined force and/or position has been reached. Subsequently, the first and second components are welded to each other, the drive system is actuated, and the lower and upper tools are moved relative to each other.

The invention relates to a welding technical field and provides a crawling welding robot. The crawling welding robot includes a vehicle chassis and two crawler wheels connected to two opposite sides of the vehicle chassis, respectively, wheel carriers of two crawler wheels are movably connected with the vehicle chassis. In this way, when the crawling welding robot moves on a non-planar surface for welding, the two crawler wheels can freely adjust its posture relative to the vehicle chassis to adapt to the surface for welding and improve a degree of fit between the two crawler wheels and the surface for welding, making the moving direction of the crawling welding robot easier to be controlled and reducing a probability of the crawling welding robot slipping or falling from the surface for welding.

Disclosed is a welding device, which includes a drive unit, a first connecting rod, a second connecting rod, a welding head and a welding base. The drive unit is in driving connection to one end of the first connecting rod and one end of the second connecting rod; another end of the first connecting rod is in driving connection to the welding head, and is configured for causing, being driven by the drive unit, the welding head to move in a direction close to or away from the welding base; and another end of the second connecting rod is in driving connection to the welding base, and is configured for causing, being driven by the drive unit, the welding base to move in a direction close to or away from the welding head. The present application can ensure the synchronous movement of the welding head and the welding base.
