When you clean the oxide layer with a stainless steel wire brush that has not been cross-contaminated with other welding material before beginning your project, you set yourself up for success.

Welding | Princess Auto

GLOSSARY OF WELDING TERMS. Arc [Arc Length] - The physical gap between the end of the electrode, and the point where the arc makes contact with the base metal. Brazing - A group of welding processes in which a groove, fillet, lap, or flange joint is bonded by using a non-ferrous filler metal having a melting point above 427°C (800°F), but below that of the base metals.
