Q&A for How to Weld Lead

Personally I would recommend using a local sheet metal store; however, if this option is not available, check your local hardware store or purchase it online.

The process is pretty similar to lead welding, but aluminum is a little tougher to work with. You're going to need to clean it first, then begin heating it with a TIG welder. Use an aluminum filler rod instead of a lead one.

You generally need to stick to the same type of metal in welding. Since lead melts so quickly, it's hard to get it to bond properly with something like steel. You might be able to melt the lead, then dip the steel into it to coat it.

Maybe several decades ago, but nowadays due to the well documented negative health effects of lead, it is highly unlikely. Today, most cooking bakeware/pots/pans/colanders, muffin pans, etc., are either riveted, spot welded, or TIG or MIG welded, using metals that are generally regarded as "food safe."
