PICKLEX 20 - Instructions For Welding (when performed per AWS specification)
NOTE: FOLLOW THE INSTRUCTIONS COMPLETELY TO AVOID POSSIBLE FAILURE
Application:
Prepare the surface for Welding on Cold rolled steel and Hot rolled steel, Stainless steel (also on any Non-ferrous metal surface)
De-greasing:
In case of new metal with only light mill oil, Picklex® 20 should be able to remove it. Otherwise, de-grease the welding area to completely remove any heavy oil, grease, soil etc. and dry the surface before applying.
For visible Rust:
- For flash rust: Do not do anything. Picklex® 20 will remove the flash rust completely
- Heavier rust with hard crust: Use a wire-brush to break the hard crust and remove all loose rust
Process:
- Just spray or brush Picklex® 20 on the metal surface (do not put too much product on the surface). Apply on a larger area around the welding area.
- Wait about a minute then wipe off to remove the excess from the metal surface.
Heat dry by a heat gun (Picklex® 20 coating can withstand over 2000°F) & perform Welding
NOTE: Remove the weld scale by a wire-brush and spray the welding area with Picklex® 20 to provide rust protection and also provide good bonding with the top coating.
Performance and Benefits of Picklex® 20:
- Completely prepares the metal surface by removing mill oil, cutting fluid, flash rust and applies a conversion coating which allows welding to be performed through the coating.
- Increases weld strength considerably on steel
- Does not cause hydrogen embrittlement and so the chances of weld failure is almost zero, which means almost no re-work.
- There has been zero welding failure since 1998 (no re-work, saving a lot of labor, time & cost)
- Acts as an anti-spatter saving labor & time
- Spraying Picklex® 20 on the welding area provides a very long-term indoor rust protection
- Provides much better adhesion of the welding area with the top coating
