Making joint design, equipment choices for successful orbital GTAW

September 1, 2015

By: ,

Orbital welding is a straightforward concept, but the many choices in joint design and equipment features can turn even a simple orbital welding project into something complex. Industry veteran V. John Jusionis discusses three common joint designs and several key equipment features to produce a successful outcome.

Electroslag cladding provides alternative to standard cladding techniques

August 25, 2015

By: ,

Cladding, often used in manufacturing or repair, is a good way to conserve an expensive alloy. Weld cladding techniques can be manual or automated. A conventional automated technique is submerged arc strip cladding (SASC), but this isn’t the only process. Electroslag strip cladding (ESSC) is a viable alternative.

Harvesting a bumper crop of bumpers

August 24, 2015

By:

When Grant Mallicote’s father had a bumper-crumpling collision on the family’s ranch, Grant figured he could save his dad a few dollars by fabricating a replacement bumper. He used some tube, plate, a welding torch, and some ingenuity to make a bumper, and eventually it became a bumper business, Bodyguard Truck Accessories.

Oilfield components fabricator finds success in sawing heavy-wall tube

August 24, 2015

By:

When oilfield components and systems supplier Tri-Alta used an old manual band saw for cutting tube to length, it experienced no shortage of difficulties in blade failures, inaccurate cuts, and part misalignment. The company invested in a modern band saw from Behringer with automated downfeed pressure sensing, blade tension monitoring, and a material handling system.

Minimizing effort, maximizing distance

July 21, 2015

By:

A golf club shaft looks like an ordinary tube, but it’s not. Quite a bit of engineering goes into manufacturing the tube and drawing it so it has the optimal characteristics—lightweight without being flimsy and elastic enough to pack a wallop. Editor Eric Lundin interviewed Scott Cokeing, director of engineering and global quality True Temper Sports, about one of the company’s manufacturing processes, variable wall technology.

Orion Drilling Co. has rigs, will travel

July 16, 2015

By:

Before purchasing a 3-D CNC cutting system from HGG, oil rig builder Orion outsource quite a bit of its work. In addition to being at the mercy of its subcontractors’ lead times, Orion had to deal with their quality, which often wasn’t sufficient. The machine has been such a productivity enhance that Orion estimates the ROI period to be one year.

Ag equipment manufacturer switches to corrosion-free, worry-free, couplings

July 15, 2015

By:

Horsch Maschinen GmbH, an agriculture implements manufacturer, experienced corrosion problems related to the tubular couplers used for its hydraulic systems. It switched to couplers manufactured by Voss Fluid GmbH, which are much better at standing up to the corrosive effects of common fertilizers.

Minimizing scrap on laser welding mills

July 9, 2015

By:

Laser welding on a tube or pipe mill wouldn’t be very effective without a good control system. Eric Lundin interviewed TRUMPF to learn about the capabilities of the company’s SeamLine and SeamLine Pro systems.

Keeping it together at 330 MPH

June 29, 2015

By:

Top Fuel races are a dazzling sight, covering 1,000 feet in little more than 3 seconds. The drivers get the glory and the engines get the attention—they develop approximately 10,000 horsepower—but underneath the car’s exterior is a marvel of modern engineering: a tubular chassis that somehow holds together through 4G of acceleration during the race and the even harsher 5G of deceleration when it’s over.

Lean manufacturing in producing square, retangular tubing

June 24, 2015

By:

Tube and pipe mills conventionally use a set of tooling for every tube or pipe diameter, and the tools are mounted to opposing stands. Cage forming provides an alternative forming process that uses a single set of tools.

Fabricators flying ultralights

June 24, 2015

By:

Most people who own ultralight aircraft buy them fully assembled, but this isn't the only option. U-Fly-It, DeLand, Fla., lets the buyer be the builder if he's handy and has about two weeks to spare.

Troubleshooting, traceability for tube, pipe producers

June 2, 2015

By:

The adage “two heads are better than one” can be applied to tube and pipe mill monitoring systems. Monitoring the forming process is a good idea, and monitoring the welding process is too, but using a combination system that measures both yields additional benefits.

Best coolant practices make perfect

May 28, 2015

By:

Taking all of the necessary parameters into consideration when designing a tube or pipe mill can be a big task, but it doesn’t have to be overwhelming. The main considerations include all of the cooling system capacity and location, the type of coolant, the filters and skimmers to be used, and local water quality. Making these decisions early, and incorporating them into the mill’s design, maximizes the cooling system’s efficiency.
