No, not repairs, testing was on production work. Silver soldered joints are very good at resisting shear forces(as Glenn points out with boilers). The advantage over welding is that there is no diffusion zone where the steel loses its properties as it basicaly gets burnt as you weld it. It also enables you to join materials of different properties which can be difficult to do by welding. When pulling at 90 degrees angle to the soldered joint failure happens fairly quickly, but when the force is in the direction of the seam it resists often better than the base material. Silversoldering is also very good for fusing ferro to non ferro metals. For repair I usualy add a new piece to the broken part so I can make a Z or S form seam which withstands almost all forces in all directions and file/fit the least complicated part of the piece to be repaired. Silversoldering/brazing is a technology for people familiar with it, good results come with experience and doing the work often. |
