Disadvantages of GTAW Welding

1.) Slower travel speed
2.) Lower filler metal deposition rate
3.) Hnad-eye coordination is a required skill
4.) Brughter UV rays than othe processes
5.) Equipment cost can be higher than other processes
6.) Concentrations of shielding gas may build up and displace oxygen when welding in confined areas - ventilate the area and/or use local forced ventilation at the arc to remove welding fumes and gases. If ventilation is poor, wear an approved air-supplied respirator
