Fixing your boiler or installing a new one can be a daunting task. A boiler's tank must be secure and leak-proof, and the entire boiler has to be secured to the floor. Besides a plumber and/or an HVAC contractor, you may also need a stud welder. A stud welder performs many tasks, but when it comes to your boiler, this is how he or she will install and repair your boiler.
Boilers tend to be very large pieces of heating equipment, taking up at least a three-foot by three-foot by seven-foot space. Not only are some of the parts welded together, but the boiler is also bolted to the floor. Depending on the model and size of the boiler, it may also be bolted to the walls behind it for added stability. Boilers vibrate quite a bit, and when they are bolted down and in they are not shaking so much that parts come loose. As part of the installation process, the stud welder will use a stud welding gun to melt the bolts into the floor as the welder drives them. Almost nothing can pull the bolts back out, thereby permanently securing your new boiler to the basement floor.
Stud Welding the Boiler's Tank
In addition to securing the boiler to the floor, the tank needs to be tightly sealed to prevent leaks, drops in pressure and even explosions. It is a stud welder's job to drive steel studs through the boiler's tank walls while welding it watertight. Stud welder guns do both jobs at the same time, and it may be the same type of equipment that the welder used to secure your boiler to the floor. When the job is done expertly, it takes years and years to wear the tank down from the inside out. Even then, other parts of your boiler will be replaced or repaired more times than there are bolts in the tank seams.
Boiler Repairs with Stud Welding
Stud welding machines can seal off leaks in your boiler by either A) welding the leak shut, or B) by driving studs through a steel patch over the leaky areas and welding the studs and the patch into place. Most stud welding contractors prefer the former solution to the latter because not all boilers and boiler leaks are located in places that are conducive to driving studs through them. Your stud welding contractor will discuss with you what your boiler installation and repair options are.
