Wedge welders allot for metal fabricators to make fine corners and similar shapes. It's a really handy tool. We're going to get some corner and wedge welding done, too. http://www.polyweldusa.com/products/wedge-welders
Burnback uses a special kind of welding that requires heavy amounts of electricity. They attach three wires to whatever they are welding creating a loop and a ground. They then power on their welding device and it literally instantly fuse things together. If we could make a portable version of this device I think it would change the world.
My cousin just got a job as a tax accountant. We're really looking forward to having his expertise for our tax filing next year. It'll be our first time filing a joint return, so we're pretty clueless.
My cousin has been going to work with local roofing companies every year for the past seven or eight years. He usually helps with setting up scaffolding, and edge protection. Sometimes that's the only thing between these workers and a long drop!
