How to Spot Weld Steel
Welding projects can come in many shapes and sizes. Preparation is the key to a successfully welded project. Before you dive in and start welding something, make sure to have a plan of how you are going to position each piece you plan to weld. Once you have the plan of what you are going to weld, you need to tack weld or spot weld the pieces together before you weld an entire seam. It is necessary to spot weld pieces together first because a piece of metal can warp if you just start welding from one end to another. Follow these steps.
