I find it very amusing that when you are challenged you always resort to name calling and "troll" is always your go to word. You must have been a real spoiled brat growing up.

Now, getting back to the topic.....

Anytime you beat metal on a hard surface such as a dolly you thin that area, essentially moving or stretching the metal in that area. When you move the metal you are taking it from that area and moving it outward causing excess metal or warping to the outer areas. Excessive heat from welding will warp metal but heat is also how you bring it back as metal has memory. You do not use a cutting torch to heat the metal, you use a low oxygen flame such as a bud tip or for narrow areas, as in the OP's situation, a pencil flame like from a small brazing tip. Heating one side and applying a cold wet rag to the other restores the memory of the metal and takes the warp out.

If all is done well, some grinding and very minor filling is all that is needed.

Troll on....
