What is the best and/or standard method for removing a welded electrical connection. Specifically the connection on an automotive alternator rectifier diode stem and the connector assembly is welded. A little glob of copper sitting on the tip of the stem joins the copper runner of the rectifier to the diode. I take it you would have to heat it to a pretty high temperature to reflow this connection. Just cutting the stem isn't acceptable. All I could think of is a mechanical grinding of the joint to remove the welded material. I want to do as little damage to the components as possible.
