Induction Heating with Submerged Arc Welding

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.

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.

Naval Defense Contractor Builds Smarter with Leasing

US navy ship

A Red-D-Arc customer recently won a large naval defense contract that would require a substantial amount of hard automation equipment. This shipbuilding company was able to leverage Red-D-Arc’s Welderlogistics Lease program to acquire new weld automation equipment for the duration of the defense contract. With the help of over 200 pieces of leased equipment now in their fleet, this customer has grown their business considerably, and without the need for large capital expenditure.

Leasing equipment has many advantages for organizations that want to expand their business by bidding on large contracts, without the risk of tying up capital in depreciating equipment.  All leased equipment comes with a full factory warranty for the duration of the contract and will be repaired or replaced without charge in the event of breakdown.

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:
