How to Hammer and Weld Sheet Metal

Hammer Sheet Metal

• 1

  Position the sheet metal over an anvil. Hold the side of the sheet metal, using pliers.

• 2

  Strike the sheet metal to spread and harden the surface, using a basic ball-peen hammer.

• 3

  Strike the sheet metal to stretch and flatten the surface, using a planishing hammer. The hammer does not leave marks on the sheet metal. A dinging hammer is also used to flatten sheet metal.

• 4

  Strike the sheet metal over a curved anvil to curve the sheet metal, using a shallow-domed face hammer. Turn the metal around the curved anvil and strike with the head of the hammer until the desired curve is achieved.

• 5

  Strike the sheet metal to make textures on the surface, using a texturing hammer. Texturing hammers have divots and designs on the face of the hammer.

Weld Sheet Metal

• 6

  Insert the sheet metal into a vice grip. Turn the handle of the vice grip in a clockwise motion until the sheet metal is locked in place.

• 7

  Turn the valve of the gas container in a counterclockwise direction to open the gas valve.

• 8

  Point the nozzle of the metal inert gas, or MIG, welding gun 1 inch from the sheet metal.

• 9

  Pull the trigger of the MIG welding gun in short bursts of 1 second each. Move the tip of the welding gun 1 inch per burst. Continue until the sheet metal is welded together.
