Assume the legs are equal, unless otherwise noted. Types of welding joints There are five basic types of weld joints: Butt Joint: It is a joint between two materials lying in same plane. It’s Key to the Best Welds. This type of joint may one-sided otherwise dual sided. The size of a fillet weld (Figure 24) is the length of the legs of the weld. Each joint’s design affects the quality and cost of the completed weld. The 5 Types of Welding Joints. This means that the filler only fills up part of the gap between the metals. Edge Joint. There’s no-weld defect that’s exclusively caused by the use of butt joint. It’s basically two base metal perpendicular to one base metal forming a cross. 6- U-groove weld 7- J-groove weld 8- Flare-V-groove weld 9- Edge weld 10- Corner-flange weld. WelditU is an independent, reader-supported site. 7.18. Construction of a box or a box frame uses this joint type. They are placed in the form of letter T. This type of weld joint requires the use of the fillet weld that is applied on both sides of the metal. Different Types of Welding Joints Good weld penetration is often difficult with this type of joint (Figure 5 View A). The American Welding Society‘s (AWS) definition of a joint is “the manner in which materials fit together“.. While on fillet weld, it’s a little bit complicated. The root opening must accommodate the diameter of the filler material, which is chosen based on the base metal thickness and the welding position. Here we have two main types of weld joint. Butt Joint. The figure below shows the five basic weld joints. The joint formed by welding the edges of two parts together are called edge joint. Though in another welding method such as slot and plug weld a special preparation is required to give some kind of pathway for welding. This article will try to break down all things that we know about the welding joint. Weld types used in lap joint: Bevel-groove weld; Fillet Weld; Flare-bevel-groove weld; J-groove weld; Plug weld; Slot weld; Spot weld; Edge joint. Welded joint where the weld metal fully penetrates the joint with complete root fusion. The butt joint is relatively easy to prepare and perhaps the only joint that’s suitable for automatic welding. Tee welding joints are formed when two members intersect at a 90 deg angle which makes the edges come together in the center of a plate or component. Though grooving is done like those of bevel, only one of the base metal is chamfered. To control the effect of accumulated heat on metal materials, multi-pass welding instructions may specify an interpass temperature. You create the wider weave bead with greater side-to-side motion. In this type of welding joints, the workpiece is joined by placing it on the edge, whose surface is at 90 ° from each other.

Butt Joint: Figure shows common applications of double welds in basic joint designs. weld location. Butt welding joint or square groove weld is a very simple and common type of welding joint. This type of weld consists of one or more stringer or weave beads. Thus an extensive knowledge about how to configure a proper welding joint can tremendously help the engineering process so that it can minimize any potential failure of the weld joint. WELD JOINTS. Weld reinforcement describes the metal that exceeds the quantity needed to fill a joint at the face or root. The double-bevel tee joint handles heavy loads when welded from both sides (Figure 4 View C). 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 between two overlapping materials. Sometimes, the groove face and the root face occupy the same surfaces. One common variation is resistance spot welding (RSW) which places a series of spot welds along the joint (Figure 21). These joint types … Although found in plate work, this joint is more common in sheet metal work. This can be done by welding completely through from one side. This happens by passing an electrical current through two or more sheets of metal clamped between copper electrodes. Make a narrow stringer bead by using little to no side-to-side weaving motion. The problem of corrosion can also occur because of the wide contact area on which the material overlap. Welders describe the point where two or more base metals meet for welding as the weld joint. Shielded Metal Arc Welding Machine Parts And Process. You’ll find the tee joint in many types of welded metal structures. T-Joint 5. They include: Butt joint, Figure 2. • Square-groove butt weld. Type # 1. The groove face is the surface of a member included in the groove (Figure 8 View A). Now as a hobby, he enjoys researching, testing and writing on welding topics. Several things that you should note for yourself when you’re welding or inspect a joint are its angle, its groove shape, its root, and its weld size. Made in the groove between two members of a work-piece, groove welds (Figure 14) are adaptable to many butt joints of differing thicknesses.
