AWP | Automatic Pipe Welding
AWP = Automatic Pipe Welding | Automatic Pipe Welder built to order to weld pipe ranging form 4″ to 48″ diameter and lengths up to 48′. The APW integrates a tracking system, control, Manipulator, Positioner to adopt 1 or more arc welding processes (TIG, PAW, MIG, SAW….) in a completely dedicated package that produces hight quality full penetration welds up to 5 times faster than manual welding.
In recent years, many fabricators are re-evaluating their work flow and plant layout to improve productivity, trying to increase the percentage of joint to be welded in shop to utilize the quality and productivity advantage brought by in-position mechanized welding. Such approach by rotating the work piece typically requires a range of positioning equipment such as turning rolls, head & tail stock, manipulators, with specially designed tools in case work pieces with asymmetrical configurations (elbows, flanges) are required to be welded.
APW is a fully automated work cell developed specially for industrial pipe prefabrication, it enables sub-assemblies to be prepared and welded from basic components (pipes, flanges, elbows, etc…) in the workshop fora variety of industrial sectors:
- Refineries and power plants
- Shipbuilding and offshore platforms
- Chemical and food pressing plants
- Gas expansion and distribution stations
The APW integrates tacking system, control, manipulator, positioner to adopt 1 or more arc welding processes (TIG, PAW, MIG, SAW…) in a completely dedicated package that produces high quality full penetration welds up to 5 times faster than manual welding.
Configured for easy setup and operation, the work cell can process spools from 4”- 48”and up to 48’ in length.
APW Automatic Pipe Welder with gear positioner for pipe clamping and rotation
The system is typically made up of a manipulator on motorized carriage, a set of welding equipment, idlers on carriages and a system control with pendant highlighted by a precision positioner for rotation as well as tilting in some cases.
Pipe welders consists of a gear positioner has the ability to control the rotation with the precision required to achieve accurate travel speeds during the welding process, regardless of pipe diameter. Gear box of the positioner produces the required ratio and self locking function to maintain the weight in case of stoppage or failure. Such features are critical for high precision welding processes such as TIG, PAW and full penetration root pass welding.
The gear box and motor assembly is located inside the welded structure with panel access for easy maintenance and service.
A 3 Jaws self centering chuck uses hardened tips to ensure good grip on the pipe or fittings with various diameter capacities. Center of the chuck is aligned with the base track system and the idler for ease of setup and proper welding position.
PPAW Pipe welders with pressure roller and rotators are commonly used for clamping, rotating, and tilting (optional) of pipes with elbows or other accessories on both ends that can’t be effectively clamped. Below is a summary of the benefits that it brings:
• They can be used for pipes with elbows, Tee pieces, or other offset loads.
• A wide range of pipes can be clamped. The infinitely variable rotary speed is not affected by the size of a pipe because of its separate drive unit.
• Quick precise centering and clamping without chuck, clamping shoe, etc
• Flexible pipe handling – pipe can be clamped at its center of gravity. Tilting moments and supports are irrelevant in most cases.
• It is possible to center two pipes with the same diameter.
• Low investment compare to chuck clamping pipe welders
Standard pipe rotators are designed to rotate work pieces 360° with forward and backward tilt from horizontal. Rotation and tilting may be performed independently or simultaneously. The tilting section consists of the drive and roller box, holding column, clamping arm, and pressure roller. Manual vertical height adjustment of the clamping roller system is included as standard on all units.
AFW Automatic Pipe-Flange Welders provide maximum versatility and increased productivity in welding flanges or other accessories to pipe ends with the below features.
- Field proven precise rotation speed control protected against high frequency interference with speed holding accuracies of up to 0.5%
- Pneumatic Clamping provides motion and pressure to maintain tight fit of flanges or other assembled parts
- Machined face plates or custom engineered tools to hold and center flanges / parts to pipe ends accurately and effectively.
- Integral mounting leveling pads
- Optional in-feed and out-feed conveyor systems to minimize equipment down time for mass production.
