pipe stands for welding pipe

We are pleased to announce the launch of a new product in our weld automation category.  Red-D-Arc now offers adjustable pipe stands with a carrying capacity of up to 4 tons, in both low and high profile versions. Combined with our turning rolls and positioners, these stands offer an effective solution for supporting pipes during the welding process for both manual and automated applications.

“Pipe stands with a carrying capacity up to 4 tons… low and high profile versions available.”

Our pipe stands feature polyurethane rollers and have been fully UL and CE tested.  All of Red-D-Arc’s weld automation equipment has had its weight capacity UL verified to ensure safety and quality. This is a first in the weld automation industry.

Available Models:
2 Ton Adjustable Height Pipe Stands
4 Ton Adjustable Height Pipe Rollers

Pipe Welding Methods and Equipment

Pipe welders at work
The method you select for welding pipe will depend on the location where the welding is taking place, materials and pipe size.
For welding steel pipes in the open (e.g. pipe installation in trenches), manual arc welding (SMAW) is most common. This technique used is downhill using cellulosic electrodes (also basic electrodes are used for higher strength steel applications). A root pass and a hot pass are followed by the fill passes. The weld is finalized by the top pass. Welding units optimised for downhill welding are utilised.

Welding Smaller Pipes

For small diameter and short length pipes which are free to rotate, the pipe is rotated while the welding torch is held stationary. The processes used are MIG (GMAW) and TIG (GTAW). In the case of TIG welding a wire feeder is necessary. A process cell is best for this type of welding.

Welding Large Pipes

In applications involving larger pipe sizes, welding is generally carried out using the orbital process. MIG is usually employed, but TIG with automatic feed of the filler wire can also be used. Orbital process using closed head welding units is also utilized for applications where smaller pipes cannot be rotated.

There are a number of advanced methods of depositing pipe welds currently in use. These include precisely controlled short circuit transfer for root pass (Miller – Regulated Metal Deposition), optimized pulsed welding (Miller – Pro-Pulse) and high frequency waveform control (Lincoln – Surface Tension Transfer) in order to speed up and improve the quality of the pipe welds.

Red-D-Arc has a wide range of pipe welding equipment for rent including the following:

“You should give as much consideration to the preparation as you do to the actual welding”

Pipe welding is utilized all around the world in diverse industries. A variety of pipe sizes and material grades are joined to manufacture components of various shapes and lengths – from a few feet to many miles. Even though most pipe welding jobs have custom specifications – there are some fundamental aspects of pipe welding that form a common thread for welders and welding engineers alike in order to achieve high quality welds in pipes.

 

Selecting The Right Pipe Welding Equipment

pipe-welding-orbital
Equipment selection is the top requirement for producing good quality pipe welds. The highest priorities when selecting welding equipment for pipeline welding are reliability, consistency, accuracy and process control. It is also critical that the equipment is easy to use and the controls are intuitive. In addition to equipment performance, the work environment also needs to be a key factor for equipment selection. There are pipe welding configurations designed for offshore welding, remote land based pipeline welding, general fabrication shop use and custom configured automated pipe welding systems. Selecting the right one can be a daunting task – it is always good practice to seek expert advice.  Be sure to ask about the various options, capabilities and limitations of each system. When welding CRA (Corrosion Resistant Alloy) grades, it is necessary to use weld purging in order to guarantee the corrosion performance of the root run. The importance of this should not be underestimated.

Red-D-Arc has launched an exciting new product that is designed to increase the productivity and efficiency of pipe welding. The Red-D-Arc Process Pipe Cell with oscillating welding torch is a dual wire feeder, multi-process welding cell. The system is easy to set up and operate. It reduces weld operator errors, reduces welding time, and increases deposition rates, productivity and arc-on time.

A variety of welding power sources and wire feeders can be used with the system including Miller RMD PipeWorx 400 and Lincoln STT S350, S500 and S700 Power Wave systems, with all welding functions controlled via a remote interface.

Root passes can be performed manually with solid wire using either RMD or STT technology (instead of manual GTAW or SMAW) followed up by hot passes and cap passes either solid-wire or flux-cored) with the jammer-style weld oscillator.

Choose the welding positioner, welding chuck, turning roll set or headstock to suit your specific needs. All positioning functions including welding head manipulator, oscillator, welding positioner and turning rolls are managed via a single control.
