Most of the time the easiest way to cut a weld out is with a torch (either plasma or gas). These usually leave a rough edge though, so it's best to have a grinder to use when it's cut.
A butt weld is a weld made between two straight cut profiles , a socket , or plug weld is made between a surface and a hole.
Leg of the weld. Fillet is the part you cut off e.g. a corner...
You should not weld on concrete, as it can explode if heated
Basic test is to cut across the weld and polish the metal. Most times the weld can be seen as a different shade. Inclusions and incomplete fusion are visible You can cut strips across the weld joint and bend them to look for fracturing. Ultimate test is to x-ray the weld. Defects and incomplete fusion can be seen. Same process as an x-ray of your body. Also a section can be cut from the joint and subjected to a tensile test where the piece is literally pulled apart. A good weldor knows when he has produced a perfect weld just by observing the weld bead as it is deposited. Using the correct electrode produces a weld slightly stronger than the base metal.
To measure penetration of a weld, one must cut and etch the weld, preferably on a test coupon. Etching is just using an acid that will discolor the weld metal so that there is a visible difference between the weld metal and the base metal. Once the acid has taken affect, one can measure the weld using calipers or a similar measuring device.

Cut & weld
Requires welding like a muffler. If you can weld, cut off the old one & weld in the new.

They are structural, so, you have to cut them off, and weld the new ones on.
If you know how to weld and cut steel - sure. Otherwise - no.
