In this video...Mig Welding settings, techniques and tips for a 5g 6 inch sched 80 pipe with downhill root, uphill fill and cap

In today's episode we'll be going over a D1.1 1G 1" thick welding plate. We'll be using .045 ER70S6. 1G Pulse Spray mig

The 3G plate test is sometimes used for MIG welding certification tests.

This video will be particularly helpful for a 3G certification test with uphill and downhill root passes.

An excellent way to transition to pipe welding is to weld plate first.
As long as thickness, bevel angle, gap, and land are the same, the same settings work on pipe so it makes sense to establish settings on plates

Sometimes welding procedures specify downhill root and other times uphill is specified. It is great to be able to do both so you will be ready either way.
uphill root voltage and wire settings are a bit lower but is really not more difficult than downhill once you nail the settings

Can one Technique work for all positions?
This simple technique basically just traces the front edge of the puddle where the rubber meets the road. But Cut and Etch testing is still one of the best ways to verify your technique and settings

Mig Welding outside corner joints and testing them using the cut and etch test.
C25 gas was used along with .035 (.9mm) ER70s-6 wire.
Thermal Arc fabricator 252i welder (very finicky) was used.
Uphill single pass weld tested against 2 pass weld with downhill root pass.
