Brazing Mild Steel

Mild steel is a durable, inexpensive metal alloy containing up to .3% carbon, that is neither ductile nor brittle, and is used in a variety of products:

  • fence posts
  • street signs
  • construction
  • motorcycle frames
  • scaffolding
  • shelving and more

In this video, square steel is joined to rectangular steel with SSF-6 and an oxyacetylene torch. SSF-6 provides a perfect color match and better finish than MIG welding, with a bond of over 70,000 PSI.

Tips:

  • Be sure to pre-clean mild steel prior to brazing or soldering, as impurities can impede the flow of the silver solder’s flux.
  • When pre-heating, observe the color change of the steel, indicating proper application temperature.  (Avoid bright red steel)
