At the end of the reference line, a straight or wavy line is used to represent a seam weld. Electron beam welding: An electron beam is concentrated on the seam to melt the metal and create a weld. These welds can be applied on varying angles but this would be the most prominent. I would first of all differentiate between the terms seal weld and seam weld. The weld dimension is indicated in the parentheses to the left of the weld symbol. Dual reference lines are used to show the arrow side when different types of weld are applied on both sides. This number is usually placed to the left of the welding symbol. org Resistance Seam Weld Symbol. This type of weld can be created using two methods: Resistance seam welding. The strength value of a seam weld is placed ____ the weld symbol. Fewer errors are a benefit of this approach. . The first step in edge joint welding is to clean the surfaces that will be joined together. Overall, there are three different possible positions for a weld symbol in the welding symbol: If the weld symbol is on the bottom side, the. Detail drawings shall clearly indi-cate by welding symbols or sketches the details of Resistance spot weld – The symbol is a circle similar to the shape of any spot weld. by welding, binding with adhesives, riveting, threaded fasteners, or even yet more bending in the form of a crimped seam.
