tungsten inclusions

tungsten inclusions are caused by what?

---------------------------------------------------

this might sound too obvious...but tungsten inclusions are caused by tungsten dipping in the puddle, getting broken off after sticking it the puddle, or spraying in the puddle from using too large an electrode.

exceeding the amperage carrying capability of a certain size electrode will also cause the tungsten to take a crap in the puddle.

tungsten inclusions are extremely dense and show up on an xray negative like a light bulb.

usually the limits are about the same as for porosity. but sometimes, since it shows up so bright on an xray film, xray techs or inspectors can be over zealous in failing a weld due to tungsten inclusions. it just sticks out like a sore thumb.
