Welding Manipulator—Welding Column And Boom
Welding Manipulator-Welding Column And Boom
In addition to submerged arc welding equipment, other welding operations can be handled by a variety of “general” welding manipulators. Workpieces are placed precisely and rigidly on welding manipulators so that the welding arc is aligned correctly. There are also options for positioning and holding welding heads for safe, consistent production, pressurized and gravity-fed flux recovery equipment for recovering and recycling valuable flux materials, seam trackers that conserve material by maintaining even, uniform weld lines, and more.
- Power Cars
Workpieces are moved into a better position for welding by power car weld manipulators that travel on rails or tracks. Crane and lift features are available on some models for added versatility. In many cases, tracks/rail can be extended to cover larger areas for large-scale welding. Power cars can cover significant distances, up to 20′ linear. Variable speed operation facilitates precise positioning with this electrically powered device.
2. Cross Slides
These cross slides connect the weld torch to the welding equipment at the end of mechanized welding systems. With them, the torch’s position can be adjusted precisely. Cross slides are available in both manual and powered versions. Depending on how the slide is mounted, single-axis cross slides can be adjusted vertically or horizontally; dual-axis cross slides can be adjusted both vertically and horizontally.
3.Submerged Arc Welding Equipment
A submerged arc welder forms an arc between an electrode that is continuously fed which is submerged under a layer of flux powder and the workpiece. In most cases, electrodes are solid or cored wires, but they can also be strips of sheet material or sintered materials.
Subarc welding can be used to weld longitudinally and circumferentially. There are many applications for the process. The process is commonly used to fabricate heavy steel plates, such as welding structural shapes and manufacturing machine components, as well as to construct pressure vessels and storage tanks. In the shipbuilding industry, submerged arc welding is typically used for joining and fabricating sub-assemblies, as well as for surfacing, buildup, and maintenance.
In comparison to other types of welding, submerged arc welding has a higher capital investment, but the productivity gains make it well worth the cost. The proper equipment is essential for maximizing the benefits of subarc welding.
The SAW equipment required is as follows:
* A welding machine or power source
* Electrode material
* Welding head and control system
* For automatic welding, using the welding torch or using the welding gun and cable assembly for semiautomatic welding
* The flux hopper and feeding mechanism
* Welding flux oven
* A travel mechanism for automatic welding
A few variations in equipment can be made based on what you expect from the Sub arc welding process. It is possible to improve both travel speed and deposition rate by using multiple wires instead of only one electrode. Different polarities can also be applied to multiple electrodes using multiple power sources.
Advantages of Sub Arc Welding Equipment
Submerged arc welding comes with numerous advantages depending on the application. These benefits include:
* Strong, solid, uniform welds
* Corrosion resistant with good impact value
* Suitable for indoor and outdoor works
* Smooth, uniform finished weld with no spatter
* Minimal welding fume
* Less distortion
* Minimal arc flash, meaning minimal protective clothing required
* Easy automation for high-operator factor
* At least half or more of the flux is recoverable
