Abstract
The present disclosure is directed to a tubular welding electrode with a sheath encapsulating a flux core, where the sheath comprises a number of added pores. The added pores may provide escape paths for the outgassing of moisture and hydrocarbons from the flux core when the tubular welding electrode is baked. In addition, the added pores may be used to hold a liquid, such as a lubricant. The added pores may be introduced using a process such as laser drilling or chemical etching, and may be added to a strip of sheath material prior to forming the strip into a tubular welding electrode.
