Received an email asking how I keep plate and flat steel pieces straight when I am welding steel assemblies.

To help avoid heat distortion one needs heavy duty straight edges, lots of clamps, and a through understanding
of the non-even heat effects produced by welding.

The heavy duty straight edges that I use most often are made from 2" X 2" x 1/4" heavy wall, radius corners, square tubing cut to 8-feet, 6-feet, 4-feet, 3-feet, and 2-feet used with 8" and 12" Strong Hand clamps.
4-feet and 8-feet get the most use.

There are entire books and thousands of online articles written about controlling welding induced heat distortion.
Review a general welding text and practice.
Start with scrap to get the basics down and then start building projects.

My self-rule is to clamp the parts until the assembly can hold together in place for welding on its own.

vertigo,
"Next step: Next step is to burn galvanizing off bolt heads."

Received an email that stated,
Why do you need to burn the galvanizing of the bolt heads?"

Vertigo
So that the paint will stick to the bolt heads. Most paint won't stick to shiny galvanizing.

Here is how I remove the galvanizing.
Drill a row of holes in a piece of 1/4" thick metal.
Put the bolts in the holes.
Use my MAP gas torch to heat the bolt head until the galvanizing vaporizes. Takes around 10-15 seconds each.
(Do this in a well ventilated area. Preferably outside.

When doing metal grinding I use safety glasses, a full face shield, and a N100 3M mask.
Exposure to grinding wheel, rotary stone, and metal dust, will do serious damage over time to your lungs.
I use the Honeywell Uvex® Bionic S8500 Faceshield with Uncoated Polycarbonate Visor for light grinding and a welding automatic darkening helmet set on grinding mode for heavy grinding.

The Honeywell Uvex® Bionic S8500 Faceshield with Uncoated Polycarbonate Visor is extremely lightweight and adjustable for all-day comfort. This revolutionary face shield is designed for rugged jobs and is ideal for workers that are exposed to impact, chemical splashes, and airborne debris.
