It is a fact that when one has to weld materials in the five-thousandths inch range, the common welding processes may not be suitable. Even MIG welding or Stick welding may not be right because they would put too much heat into the metal. However, when welding thick metal you should opt for MIG welding or Stick welding as they can weld 1/2 in. material much faster.
