Grand Coulee Dam interio

Originally built in the 1930s, the Grand Coulee Dam in Washington State has been undergoing a series of maintenance projects to ensure that it will continue to produce safe and reliable power into the future. One stage of the project required the heating of a 40-ft wide, 7-ft tall outer headcover of the turbine shaft to specific core temperature.  In order to achieve this temperature, the engineers applied induction heating to one side of the workpiece.

Only when the opposite side of the workpiece reached target temperature could the maintenance engineers be certain that the required core temperature had been achieved.  The team from Red-D-Arc provided induction heating systems and assistance with training and set up during this essential part of the maintenance process.

pipeline welding project using induction heat

19 Hours Faster Than the Competition

Texas – One of our customers was trying to heat 42” diameter pipe using pear burners so that welders could weld out the joints. Our team saw an opportunity to create a solution that would help our customer get the job done much more quickly. To make this in-the-field heating job go faster, we put together a package including a Miller ProHeat 35 induction heating system, a 60kVA generator and a DP25 power distribution panel.

Red-D-Arc provided a reliable RDA Induction heating solution to a pipeline construction and maintenance company in Houston who needed to maintain consistent temperatures for their welders to weld out joints from pipes. Our induction heating specialist supplied our customer with a portable induction heating package consisting of a 60 KVA generator, a Miller Pro-Heat 35 induction heating system, and a DP25 power distribution panel. As a cost-effective alternative to their existing propane burners, induction heaters allowed them a secure heating, consistent temperature control, increased weld time, and improved safety.

With this setup we were able to get the pipe up to 250 degrees in about 5 minutes. Our customer was able to beat the competition’s target time by over 19 hours and has been asked to quote on other pipeline work for their client. Needless to say they were pleased with the solution and the opportunity for extra work it created.

Pre-weld and post-weld heat treating is critical for many welding operations. Without proper thermal manipulation, welds and heat affected zones can have mechanical properties that are undesirable. Worse yet, inadequate heat treatment can result in cracks and devastating weld failures. While temperature and time are the primary concerns when heat treating a weld, the heating method should also be considered diligently when selecting a process. Induction heating is one of the most popular types of heat treating methods, and rightfully so. The benefits of induction heating are many, and Red-D-Arc has the equipment you need to successfully implement an induction heat treating operation for your projects.

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.
