Welding Wand is an energy-independent exothermic soldering-and-welding wand constituting a cylindrical rod with diameter from 4 to 16 mm and length from 70 to 200 mm.
Welding Wand is comprised of a cylindrical
burning-down envelope containing a thickened technological exothermic mixture.
During the process of burning, a high temperature is progressed, required
solders and fluxes are released and a solder-and-weld seam is formed.
Welding Wand provides for soldering and
welding of all types of iron and steel (iron-carbon alloys) of 0,3-6 mm thick,
depending upon the wand diameter.
- Period of storage - 3 years.
- Seam length - 30-80% from working part length.
- Ignition temperature - 800°С.
- Burning temperature - 1500°С.
- Thickness of connected details: butt - 2-6
mm, lap – 0,3-4 mm.
- Strength of butt seam: 30 - 35 kg/mm2, lap seam - 40 - 50 kg/mm2.
- Firing time: 70 mm - 9 sec, 100 mm - 12 sec, 150 mm
- 18 sec, 200 mm - 24 sec ± 15%.
- Firing speed – 5,2 mm/sec ± 15%.
Note (for those who are experienced
in thermal treatment):
Seam can be strengthened up to 80 kg/mm2
(forging, hardening + aging: heating up to
800° C, cooling with water or oil, second
heating up to 500° С and cooling in
water or oil).
