WebBorate’s value was also used to deoxidize the metal surface for steel brazing. In the area of welding a borate-based compound appeared to be used as a deoxidizer for steel production between 1910 –1920. When used with welding electrodes, borax was introduced to this technology around the 1930s when structural welding became common place.
