welding burner coils?

I’ve got a question,,,,


Have you ever seen a burner coil welded? I mean when its leaking and someone welded the holes to fix it.

I realize that this is not the proper way to fix this. I was just wondering if you had seen it and how the welds held up.

Yes as a matter of fact I have done it myself. Yes as a matter of fact I have done it myself.

i might try it on this machine.

It's a lot cheaper than a new coil. We also do it a Xterior.

I have never done it but 3 different powerwashers around here have on afew different rigs.This is what they told me,sometimes it will hold and sometimes it may last a day or month or so but never last for long b/c welding makes a weak area around the pin hole that was welded.

Maybe The Wiz and Ron can make it more clear as to how long it should last.


Color not working in this tread..

Think about This.

When they make a coil they start out with Several streight peices of pipe.
Then they run it thru a machine that rolls it into a big spring (so to speak). Then they weld all of those peices together to make one coil assembly. The factory welds the coils together and it lasts 5 to 20 years.


As long as the weld is atleast as good as a factory weld why would it not last just as long as theirs.

The key to a good weld on a coil assy. Is to evacuate the water first with air. Run the air in the coils untill it is dry on the inside.

Sometimes I will actually use the heat from the burner to dry out the coils first. I run the heater only without water running thru them and dry the coils out. The way I do it is run an AC plug directly into the burner wiring bypassing the switch and pump controls. This is dangerous if you don't know what you are doing.
The key here is to burn off a little at a time so the steam doesn't get too hot. Heat a couple of min let it cool heat a couple of min let it cool You get the Idea.

understand what your saying.

I've been to the factory(tuff) where they make the coils and watched the machine roll the pipe.When they weld they are just spot welding to hold the coil together not welding pin holes that have came though the pipe itself which is a weak area in the pipe.
Just saying if I ever get a pin hole I'll replace instead of welding,its to much trouble to take out and put back in to take a change on it holding not counting the down time.
It could as you say last for 5 to 20 years but the powerwashers around here say they don't last long after welding before another pin hole shows up.I've only that one washer to get a pin hole and it was inside the pancake.
