Welding small diameter tubing can be difficult. The tight radii often require expert welders to deliver precise torch manipulation with finesse. If the welder is not skilled enough, the out of position areas are at risk of poor quality due to gravity affecting the weld pool and ineffective torch angles. If out of position welds cannot be completed satisfactorily, the part must be rotated. However, some assemblies can’t be rotated because of size constraints or they might rotate off of center. If a mechanized welding solution is desired for small diameter components, look no further than our Axxair Orbital Fusion Closed Welding Head Systems.
Closed-Head Pipe Welders
Axxair Orbital Fusion Closed Welding Systems are comprised of two main parts: the
Axxair Orbital Fusion Closed Welding Head and the Axxair Orbital Inverter Power Supply. The Orbital Fusion Closed Welding Head fully encompasses the assembly being welded. This means that an inert gas environment can be created around the part, preventing it from the risk of oxidation that it might be exposed to during a welding operation that relies solely on a gas nozzle. The Orbital Fusion Closed Welding Head also has a ring drive that enables full 360 degree motion around the weld joint, all the while keeping a consistent torch angle. Furthermore, it is capable of going over 360 degrees for when slope-in and slope-out parameters are needed.

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.

Selecting Welding Wire
When selecting a wire electrode for welding, one will most likely run into an American Welding Society (AWS) filler metal classification. A purchaser who isn’t familiar with the AWS classification system might select the wrong type of wire. If the purchaser is only familiar with gas metal arc welding (GMAW) wire and is attempting to purchase self-shielded flux-cored wire (FCAW-S), confusion may arise about the differences between the two classifications. This too could result in selecting the wrong wire electrode. To help prevent this from happening, we’ve created this welding wire reference guide to remind welders exactly what the different AWS classifications designations mean. We’ve included references for solid wire electrodes, metal-cored wire electrodes, gas-shielded flux-cored electrodes, and self-shielded flux-cored electrodes.
When one of our customers was tasked with an electrical motor shaft rebuild that required them to weld new fins onto a 7” diameter shaft, they called on Red-D-Arc’s team of experts for assistance. The job required the shaft to be preheated to a temperature of 400°F and welded using a submerged-arc process (SAW). Using the Miller Proheat 35 and Lincoln’s LT7 sub arc package, a job that was originally bid at 40 hours took just 3 hours to complete.
This innovative solution saved our customer a substantial amount of time and money. Our customer was able to keep a project —which would normally be outsourced— in house. As an added benefit, they now have a new service they can promote to their customers.

Firefighting teams are stretched thin across multiple sites and are fighting fires around the clock
Oregon: Lightning strikes have started wildfires in multiple locations from Crater Lake to the Siskiyou Mountains. Governor Kate Brown has declared a statewide wildfire emergency. Fortunately, none of the fires have yet blown up into large scale thousand acre burns, but with temperatures expected to remain in the high 90s for the next week, the fires may grow and there are number of areas with evacuation warnings pending.
Our team in Oregon responded to a call for emergency power by quickly delivering a number of 150kVA generators to the fire camps. These machines are helping power lighting and the cooking facilities that serve the firefighters. The firefighting teams are stretched thin across multiple sites and are fighting fires around the clock. With high temperatures, low humidity and wind expected to continue through the week, it’s difficult to estimate how long they might be fighting these blazes. Red-D-Arc is proud to do our part in supporting these hard working men and women in their valiant efforts to control the fires.
