2 inch Pipe 2G TIG Root-Fill-Cap
2 inch pipe welding
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 the 2 inch 2G 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
