When I go to pressure check the manifold I find leaks at the toe of the weld on the stainless side of the weld every time. So, I was wondering, which type of welding is right for stainless steel at all. Braze / bronze welding provides a strong joint and is ideal of steel frames, where a certain amount of flexibility is required. In my recherche, I realized, that you can either MIG/TIG or Stick weld stainless steel. Problems occur if the joint is designed where the weld energy comes through the copper first. tig welding copper to steels Silicon bronze works for joining copper to carbon steel as well as to stainless steel. At Lantec laser we are developing a series of tests of laser welding on bronze and stainless steel, trying to achieve balance, stability and above all quality in the solutions we offer.. However, some bronze metals contain more zinc than tin, and some contain zinc and no tin at all. The filler rod is broader than that used in brazing. Silicon bronze works for joining copper to carbon steel as well as to stainless steel.

You always want to use a technique that only flows the filler rod and does not actually melt the base metal. Braze / bronze welding provides a strong joint and is ideal of steel frames, where a certain amount of flexibility is required. Thanks Thomas, When I asked what's the best process, I meant which welding process mig/tig/oxy would give the best/strongest result. We have TIG welded copper electrical buss work together before without too much difficulty as well as other stainless, high nickle and titanium alloys (hastelloy, inconel, Ti-7).

When brazing, flux is applied to the joint, to prevent oxidation of the surfaces. Brazing-stainless steel is considered easy to perform if a basic understanding of the materials is obtained and if the applicable processes are mastered.. They appear to be great to the naked eye and the weld flows very well during the process.

I use it for creating the internal framework of my bronze sculptures: I weld short pieces of 1/2″ copper pipe between the leader and follower strips to create a rigid form before welding on the sides. Brass and bronze are alloys of copper. When brazing, flux is applied to the joint, to prevent oxidation of the surfaces.

They spread out in different areas of the flange. The reason I am enquiring is because of the tree project, we are considering having the trunk and some branches cast in bronze so we can include the names of those who perished in the fires in the tree itself. This is an alternative to traditional welding using silver, which reduces costs and the thermal effect on the parts. At Lantec laser we are developing a series of tests of laser welding on bronze and stainless steel, trying to achieve balance, stability and above all quality in the solutions we offer. I find that using the rule of 33 (33 pps, 33% on time, 33% background) provides a little bit of puddle agitation and helps keep the heat down too. Silicon bronze rod has a melting temp of around 1050°C, while stainless steel has a melting point of 1400-1450 °C. Welding Bronze If you use the same filler metal as the base metal, its welding. You always want to use a technique that only flows the filler rod and does not actually melt the base metal.

A project we are considering bidding on calls for welding copper plate/sheet to 316 stainless steel. The problem- the aluminum bronze to stainless flanges weld out very well. The filler rod is broader than that used in brazing. Brass has zinc, and bronze has tin as the major alloying elements. Now take a look how to weld stainless steel with each technology. In particular it is advantageous for joining dissimilar materials that cannot be welded together.. High brasses contain from 20 to 45 percent zinc. When properly applied Brazing-stainless permits to build strong and leak tight joints in thin wall items with minimum deformation. How to weld stainless steel? Welding brass and bronze can be accomplish using a number of welding processes. Silicon bronze wire is great for welding bronze, copper to copper, copper to bronze, copper to steel, steel to steel, etc.

doesnt matter if its lead, steel, aluminum or bronze Im sure there is a flux coated stick electrode that is made of bronze. An important aspect of welding stainless steel to copper is the physical design of the joint. The process is discussed more on adiforums.com if your interested in seeing what some pro’s say about Tig welding copper and SS. This is an alternative to traditional welding using silver, which reduces costs and the thermal effect on the parts. Like always when welding, you need the right welding machine settings. Copper, being a great conductor of heat, tends to require a significant amount of welding energy before it melts.
