6 steps to successful brazing - The Fabricator
WEBMar 7, 2006 · A brazed joint basically can "make itself"—capillary action, more than operator skill, ensures filler metal distribution into the joint. The real skill lies in the design and engineering of the joint, but even a properly designed joint can turn out badly if you don't follow proper brazing procedures.
Guidelines for tungsten electrode and color types - The Fabricator
WEBMar 7, 2006 · Editor's note: To read an update regarding tungsten electrodes guidelines, click here. Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. The GTAW process relies on tungsten's hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius.
