What problem can a long nozzle cause to the tungsten?
The problems caused to the tungsten by a long nozzle.
Nozzles are installedin the torch of the welding equipment. The nozzle is used to direct the shielding gas on the zone where welding has to be done. The dimensions of the nozzle are defined by its opening diameter and its length.The nozzle with small diameter permits the welder to see the molten weld pool. It operates at low rate of gas flow. The nozzle with large diameter gives a better shielding effect.
Tungsten electrode is covered with the nozzle...
