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
- motorcycle frames
- 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.
- 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)
