Soldering is a fundamental bonding method used in architectural metalwork—especially with copper, the most commonly soldered architectural metal. In this interactive clinic, attendees will gain a practical understanding of soldering principles and how to consistently achieve clean, strong, and watertight seams. This demonstration will walk you through the key tools, materials, and techniques needed for successful soldering. See live soldering performed on two common seam types, including one in a vertical position—a realistic challenge faced in the field.
Learning Objectives
- Learn the fundamentals of soldering; when to use it and the tools, materials, and setup required.
- Master preparation techniques; mechanical and chemical cleaning, tinning, and flux application for effective seam bonding.
- Discover how to solder accurately to form seams, perform final inspection and cleanup to ensure quality
Whether you’re new to soldering or want to refine your technique, this demo offers the foundation and finesse you need to elevate your craft.
