| UNI-5000
Universal Steel Alloy |
- Excellent
crack resistivity on difficult to weld steels
- High
strength deposits
- Impact,
heat and corrosion resistant
- Excellent
application and appearance
For joining vanadium steels, mild and medium carbon steels
and stainless steels. Ideal for use as padding prior to
applying weld protective coating. Commonly used by maintenance
departments for joining stainless steels of unknown analysis
and these steels to common steels. Widely used for rebuilding
shafts and mixing blades used in the chemical, construction
and mining industries. Great for broken stud removal.

| Procedure |
| Prepare
joint by removing damaged, dirty, or fatigued material. Bevel
heavy sections to form to 90° "VEE". For certain
high carbon or high alloy tool steels, a preheat of 400°F
(204°C) is recommended. With DC straight reverse polarity,
run stringer beads holding a very short arc. intermittent welding
may be used, especially with high alloy steel. pending relieves
streeses. Coll each pass before chipping. Deposits will take
a high polish when subjected to wear. |
