AGW Automatic Girth Welder 3 Oclock Welder - Tank Storage Mag
Red-D-Arc was featured in the December/January issue of Tank Storage Magazine in an editorial titled “Rental welding equipment for storage tank fabricators”. Tank Storage Magazine is an industry leading publication, reporting exclusively on the bulk liquid tank storage and terminal sector.

The storage tank construction industry is highly competitive and fabricators gain a significant advantage by leveraging Red-D-Arc’s rental fleet of automatic tank welding equipment. Red-D-Arc supplies specialized automatic storage tank welding equipment to companies in the tank fabrication industry for projects all over the world.

Along with our specialized tank welding equipment comes a highly knowledgeable and experienced team of Red-D-Arc technicians. Sayer Hendricks – storage tank welding equipment specialist at Red-D-Arc is quoted in the article: “A fabrication company without prior knowledge of the equipment, is able to rent a turn-key tank welding automation system and increase their welding productivity by 40-50%. With on-site training, service and support, our customers are up and running quickly and making 100% x-ray quality welds without fail”

Fast, Efficient Flux-Cored Welding with Semi-Automatic Wirefeeders

Flux cored welding with semi-automatic wirefeedersBy guest blogger David H.

Some years back I was working in a shipyard in San Francisco. The yard had several small repair jobs going, plus a fairly large project building six ocean-going barges. The supervisor who was in charge of the barge-building project was looking for volunteers to operate semi-automatic wire feeders, using flux-cored wire, to weld stiffeners to the skin of the barges. I had never used a wire feeder before, so I volunteered out of curiosity.

After a very short training period, possibly all of 30 minutes but I think a bit less, I was off and running. I was impressed by the quality of the welds and the speed at which they were deposited. Without question I was outpacing anything that could be done by stick welding, and I felt it was easier to maintain a uniform weld size too. The machine itself was light enough and small enough to move without difficulty, and the spools of wire lasted long and were quick and easy to replace when the spool of welding wire was finished.

Red-D-Arc has nearly a dozen semi-automatic wire feeders available for almost any application. We also carry fully automatic wire feeders, which are faster still and appropriate in certain circumstances – like building storage tanks –  especially for large-deposition welds.

Keeping Quality High in Pipe Welding Applications

“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.

The 5 Most Common Mistakes Found by Welding Inspectors

welding-inspection-01Welding inspectors have a responsibility to the company they work for and the general public to ensure that weld quality is satisfactory.  Failure to fulfill their duties can result in property damage, injury, and death.  Most welding inspectors, therefore, take their job very seriously.  Welding inspectors spend years honing their ability to detect and size welding discontinuities and defects.  While they must be proficient at identifying all discontinuities and defects, some of these weld irregularities are more readily detectable than others.

1. Surface Porosity

Porosity is gas that has been trapped in the weld; this results in cavity formation within the weld.  Porosity can cause reduced weld strength.  Welding inspectors who are not trained in other forms of nondestructive testing are limited to viewing the surfaces of welds.  So while not all forms of porosity can be detected by a welding inspector, porosity that extends to the surface of the weld can.

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.
