Welding Distortion is a complicated subject.
But one thing is certain…
understanding that weld metal shrinks as it cools is fundamental to understanding ways to prevent distortion.
this video addresses welding stainless steel square tubing and shows a technique for using weld sequence and direction of travel to keep things straight.
309 Tig rods are designed for welding stainless steels to carbon steels…but they are a good rod to have in your shop because 309 is a very versatile rod…good for welding pretty much any steel to any other steel in a pinch.
not necessarily the absolute best all around choice…and it shouldn’t be used indiscriminately…but 309 will usually get the job done.
Speed tacking involves setting amperage to 30-50 percent higher than normal welding amperage. Then using a torch switch or foot pedal, use very quick blasts of half a second or less to fusion tack weld.
this makes for very quick tack welding that is clean and free from oxidation.
Walking the cup is a great way to tig weld pipe and other round stuff. But sometimes, there is other stuff in the way and its just not practical.
