2g pipe welding is when the axis of the pipe is vertical and the weld is horizontal.

This is a very common weld for boilermakers except boilermaker welders also contend with very tight spaces.

Freehand tig welding a 2 inch pipe is a boilermakers bread and butter and if you have ever made a 2g weld on 2 inch or smaller, you know it gets pretty hot.

A TIG finger® lets you prop right next to a hot weld and lets you concentrate on making the weld instead of how hot your knuckles are getting.

The basic procedure for this weld is:

2 inch sched 80 carbon steel pipe

35 degree bevels 

1/8" gap

Zero land (feather edge)

1/8" ER70S6 filler

100 amps 

3/32" 2% lanth tungsten

#5 stubby gas lens cup with 15 cfh argon flow
