Weld-O

Area of Application: Arcal Weld-O is a ready-to-use X-Ray quality welding prep for aluminum and all grades of aluminum alloys. Weld-O is an innovative chemical formulation that consists of a blend of mineral acids, surface active and sequestering agents and degreasers.

Weld-O deoxidizes the surface instantly and conditions the surface for X-ray quality welding. The weld joint is cleaner and stronger. By using Weld-O, the need for wire brushing and other time consuming cleanup procedures are eliminated. A simple water rinse may be done but in many cases is not required.

Properties:

  • Appearance: Clear pink solution with acid odor
  • Specific gravity: 1.1
  • Flash point: none
  • pH: 1 - 2
  • Solubility in water: Soluble
  • Biodegradable: Yes
  • Do not dilute. Use Weld-O as is.
  • With an acid resistant brush such as a flux applicator, apply Weld-O to both sides of the area to be welded to assure a uniform weld joint and to eliminate migration and fusion of contaminants during welding. Leave it on for approximately 60 seconds or until a uniform foam blanket is noticed on the surface.
  • Wipe with a clean sponge or cloth. Then weld in your normal manner to obtain an X-ray quality weld.

CAUTION: This product contains hydrofluoric acid and should be used by qualified professionals utilizing appropriate safety gear.
