Welding Tips and Tricks

So many times I’ve had people tell me “you can’t run downhill, it’s a crappy weld”. It would be nice to see some etched samples of common applications to clear things up for people. Thanks keep up the great work!

I run downhill mig every day at work. Stainless steel trailer manufacturer. Welding in support rings is all downhill. If it’s vertical it’s downhill. Typically it is 10 or 11 Gauge stainless. Pipe welders run downhill with stick as well.

Although pipe can be welded downhill with stick. Very little is done that way. Most wps I’ve seen are strictly uphill on stick.

For root passes with 6010, a single 360 weld is the WPS for live gas taps. A bit of an esoteric application I agree, but it is done commonly. Filled and capped uphill though.

Most gas mains are tapped on the top, putting the weld in a nearly horizontal position.

Sorry, should have been a tad more specific. Residential gas service from mains. They are made on the side of the main, then, new horizontal service pipe is run parallel to the ground. That means uphill, downhill, and horizontal welds from a single pass. I'm good friends with a bloke who's been doing it for 28 years, same company. Doesn't even have a 70xx rod on his truck. The service lines are also single, continuous welds (according to my buddy).
