Soldering a Box Gutter - Stitching

Mike of Sheet Metal Workers Local 19 from ACG Roofing is soldering part of a box gutter with an Express iron. He is using a technique called stitching or bridging when you turn the heat of the iron down and lay a second bead of solder down. This is for aesthetics as well as strengthening the joint.
