Canopy brace behind the front seat where its welded onto the 7/16 tube is cracked

I've just noticed that on my RV4 that the cross brace behind the front seat where it is welded onto the 7/16 tube that goes around the canopy, the welds are cracked.

Everything else looks good, the brace where it is riveted to the skirt is normal, no cracks in the canopy.
I've had the plane for 3 years, put on almost 100 hrs on it. It has almost 600 hrs TTAF and have just noticed it. Today was the 1st time I have sat in the back seat and that is why I noticed it. You can't really see it from any other angle so it may have been like this for a while.

Has anyone seen this before? Any suggestions on what to with it.

Thanks

Tim

I must be the only one

Nope. Mine is cracked where the spring on the latch goes through. Been that way for 1000 hours.
