Bronze Welding Compression joints Flange joints 1.2 Materials Used for Pipe and Tube Many different materials are used for pipe and tube systems. A weld joint is the junction of the edges or surfaces of parts that have been joined by welding. Corner Joint – When two pieces are perpendicular to each other and one piece’s edge meets the end of the other piece’s surface, it is referred to as a corner joint. Depending upon the type of joining method and elements used to make the joint, the flexibility of the joint may vary from hinged to rigid joint condition. Permanent joints are those that cannot be undone once made – providing, in general, more stress resistance. There are five common types of weld joints used in all types of welding: corner joints, edge joints, lap joints, tee joints, and butt joints. These processes differ greatly in the manner in which heat and pressure (when used) are applied, and in the type of equipment used. 6) A welded joint has a great strength. suggest appropriate edge preparation for the given parts. Directly melt the local sheet metal material at the welding head to complete the sheet metal connection. Figure 1 shows the classification of the welding processes. With butt welds, both workpieces are arranged in one plane. It is used to joint the plates having thickness 3 mm or less. These types of welding defects are hard to visualize with open eyes and you need to look into the microscopic structure to discover defects. It is an ancient method, about 1500 years old. welding or threading. They are formed by welding two or more workpieces (metal or plastic) according to a particular geometry. They are formed by welding two or more workpieces (metal or plastic) according to a particular geometry. The main difference between these two types of weld is the type of joint. >Types of Joints < Besides different types of welds and welding beads, there are a variety of joint types used in welding.

Welding can be used by anyone from beginners to experts in order to effectively join two pieces o… Butt Joint Butt joint- a joint between two members aligned approximately in the same plane 4. The type of welded joints to be considered in this paper would be fusion weld joints in which metal is molten by creating an arc between an electrode (made of similar alloy as the parent metals or an "inert" metal like tungsten) and the parent metals. Butt Joint 3. Welded joints are made by using high temperature and riveted joints are those which use rivets to fasten two members. T-Joint 5. They are further of two types: a square butt joint( to join light sheet metals ) , a beveled butt joint( to join heavier pieces of metals) Lap joint: It is a joint … Joint between two overlapping components made by depositing a fillet weld around the periphery of a hole in one component so as to join it to the surface of the other component exposed through the hole. MIG Welding Common Joints: This Instructable will provide a short introduction to the process of MIG welding, as well as a step by step procedure in welding three common joints. 1 shows the different welding processes. The main Types of welding used in industry and by home engineers are commonly referred to as Mig welding, Arc welding, Gas welding, and Tig welding. There are two types of welds performed in six different joints. Share this Post. Welding joints is an edge or point where two or more metal pieces or plastic pieces are joined together. Welding defects are classified into the following two types. 5.27: Flanged joints circular steel pipes) that they afford difficulty for riveting. Joint Design & Welding Symbols. Before the welding procedure is happening then the preparation of joints is required. The drawings shall clearly distinguish between shop and field welds. Corner Joint 3. 29.2 THE WELD JOINT Welding produces a solid connection between two pieces, called a weld joint. Types of Welding Joints Welds Based on Configuration Slot weld. 4(a)], and zero value [Fig. These connections may be made using bolting or welding. In certain cases, a flange-type joint is also called a lap joint. Types of pipe joints are major components of plumbing system provided to connect multiple pipes. "A welding joint is a point or edge where two or more pieces of metal or plastic are joined together. very common. In fillet welds (e.g. in a T-joint) they are at an angle to each other and form a fillet joint. Often a welded joint has the strength of the parent metal itself.
