WebDec 24, 2024 · A butt-lap joint brings together components with fitted L-shaped ends, with the braze alloy fed into the space between the interlocking L’s. Pierced joints occur where one component passes through the other at the point where the brazing is completed. Each of these joint types can be designed into components that are flat or curved. cromwell richard harrisWebAs with all brazed joints, preparation and cleaning of the workpiece is essential to produce a successful joint. When silver soldering, lap type joints (rather than butt) are preferred and the recommended clearance is 0.04 to 0.15mm. Apply SIF Silver Solder flux to both joint faces before assembling the parts.
