Outdoor Oasis: Building A DIY Metal Fire Pit With Welding Techniques

Building A DIY Metal Fire Pit With Welding Techniques

Fire pits are a fantastic option for individuals who choose to spend their time outside all year round. They are not only a warm and inviting place for loved ones to congregate, but they are also a simple and reasonably priced way to increase the value of your house.

Why not create your backyard haven by taking the risk? We have some do-it-yourself welding techniques for creating a metal fire pit.

Is Building Your Fire Pit A Cost-Effective Option?

As far as adding a fire pit goes, the possibilities are virtually endless. You can easily construct your fire pit for a fraction of the price of a professional installation with a bit of forethought, the appropriate supplies, and some labor. Therefore, don't be afraid. You can design and build a fire pit that will make you the talk of the neighborhood, even on a low budget. Depending on their size and the materials you choose, fire pits can be constructed for as low as $50 to $60.

Steps For Building A Metal Fire Pit

Follow these instructions to construct your own fire pit with a multiprocess welder and plasma cutter.

STEP 1: Make your fire pit design and cut it out.

The template was cut out with a CNC table, but a plasma cutter works. Cut each piece of hot rolled steel sheet to size after marking the cut lines.

STEP 2: To achieve the desired angle, bend every steel sheet.

A metal brake works well for this phase, but you can alternatively turn the necessary parts by hand.

  1. On every steel sheet, mark a bent line.
  2. Carefully score each metal sheet along the bending line with a 4.5" Angler grinder fitted with a cutting blade or disc attachment, taking care not to cut through the metal.
  3. Pull the metal toward the scoring line to get the appropriate angle.
  4. Add a weld bead to the score line to strengthen the metal again.

STEP 3: The steel sheets' edges should be ready for welding.

Secure each sheet with a clamp on a sturdy surface. Clean the weld areas using an angle grinder equipped with a 40-grit flap disc. Eliminate any residue that might remain after the plasma-cutting process.

STEP 4: Attach two sides on a level surface.

Use clamps or magnets to ensure that the sheets are as square as possible. Next, start taking them together from the bottom, work your way up to the middle, and then return to tack in the space between the two tacks. This staggered arrangement will aid in the uniform distribution of heat input.

STEP 5: Proceed to the top after taking the bottom section.

To achieve the tightest joint possible during tacking, butt the steel together using pliers or clamps. Continue using the previous staggered pattern.

STEP 6: Continue tack welding all four sheets to one another.

With a staggered weld pattern to reduce heat input, continue tack welding all four sheets to one another, working from bottom to top.

As you go along each joint, adjust the fitment as needed. It would help if you used pliers or a hammer to guarantee correct surface mating.

STEP 7: The middle area of the interior, where the pit's bed will be welded, should be measured.

The hot rolled square bars that will form the framework supporting the logs inserted into the fire pit's bottom will be calculated and cut using these measurements.


Cut the square bar into four portions that will form the perimeter of the frame.


Cleaning and beveling each piece where the square bars will be welded together will prepare them for welding.

STEP 10:

Tack the square bar frame together after clamping it.

STEP 11:

Tack and weld the three cross-support bars into the frame to increase structural rigidity.

STEP 12: Cover the square bar frame with an enlarged steel grate.

To guarantee correct fitment, tack weld the grating to the bars. Then, finish the welds at each point of contact to ensure strength.

STEP 13: Fasten the grate to the frame of the fire pit.

Put the whole thing in a welding-friendly posture. Make one inch of horizontal downhill weld at a time. To regulate the amount of heat input, spread each one out and weld from corner to corner.

Have fun with your new fire pit!
