How To Weld Bronze To Stainless Steel. Silicon bronze works for joining copper to carbon steel as well as to stainless steel. This is an alternative to traditional welding using silver which reduces costs and the thermal effect on the parts.
Now technically this would be classified as Tig brazing because the stainless steel has a higher melting point then the silicon bronze filler rod. Aluminum bronze manifold C95400 with a make up of 83 copper 10 AL 3-5 iron 05Mn 15 Ni. Because of this you dont need the base metals to be similar so its possible to TIG braze copper to stainless steel as an example.
Si-bronze and 304 stainless steel were joined using gas tungsten arc GTA welding with two different welding filler rods matching the base metals.
Matmatch Helps You Find Evaluate And Source The Best Materials For Your Project. Weld metal consists of a mixture of materials which have unknown material properties when combined with unevenly distributed heating or stresses. Because of this you dont need the base metals to be similar so its possible to TIG braze copper to stainless steel as an example. TIG welding stainless steel is performed by using a non-disposable tungsten electrode with a TIG welder for striking up the arc.
