  • The Effects of Polarity on the Resistance Welding Process (.pdf)
    In resistance welding, both the weld heat and the size of the weld nugget can increase or decrease depending on the polarity of the current passing through the parts. This is caused by a phenomenon known as "The Peltier Effect", which is present when the weld current flows in only one direction
  • Consumable Insert Welding Procedure (.doc)
    The Robvon Consumable Insert Ring is to be used with tungsten inert gas (TIG). DC and Straight polarity is used for "TIG" welding. The weld joint and immediate adjoining area of parts to be welded should be prepared by machining or grinding. To assure consistent weld quality, cleanliness must
  • The Importance of Force Control (.pdf)
    There are many variables associated with the resistance welding process. The three primary variables are weld current, weld time, and electrode force. Secondary variables include, but are not limited to: electrode materials, electrode face size, polarity, material quality, and material composition
