Fine so long as you have the skill and the correct welder. it's lighter gage metal so you need a MIG, preferably one with shielding gas and low enough amperage so as not to burn through. Conventional SMAW (stick welding) will be impossible as the material is too thin and you'll burn through and proper prep is paramount as in removal of all the paint around the cracks (on both sides) and cleaning of all dirt and crud too.
You could also gas weld it (oxy-acetylene) if you have that or even TIG it if you have a TIG machine.
