IMPORTANT: Do not write anything on this material. Write your answers on the learner’s activity and assessment sheets provided separately.

UNDERSTAND Fillet Weld The fillet weld is the most popular and commonly used weld in industry. It requires little or no edge preparation. Single- fillet welds are fillet welds that have fillermetal deposited on one side. Th ey are limited to smaller loads than double fillet welds.Double fillet welds are fillet wel ds that have filler metal deposited on both sides toprovide additional strength. It may be equal or unequal fillet.

Types of Fillet Joint (1) Lap joint is frequently used in all kinds of work, which may be singlefillet lap joint or double fillet lap joint. The single fillet lap joint is not as strong as the double fillet lap join which is more often used on ordinary work. Single fillet lap joint should not be used if root of joint is to be subjected to bending. This type of joint should never replace the butt joint on works under severe load. (2) Corner joint is a weld joint formed when two joint members are positioned at an approximate 90 degrees angle with the weld joint at the outside of the joint members. Heavier plate can be welded if the load is not severe and there is no bending action at the root of the weld. No preparation is needed and fit up is usually simple. Half open corner joint may be used on 12 gauges up to 4.5mm. Full open joint can be cut absolutely square and suitable clamping and holding devices are needed to facilitate fit up. 2 |P a g e

(3) Tee Joint is a welding joint at the junction of two parts located approximately at right angles to each other in the form of a T. In terms of welding, thicker metals at the edge to be joined should be bevelled. There are many forms of bevelling edges for T-joint such as single bevel, double bevel, single J bevel, and double J bevel. No preparation of edges is necessary for thinner plates and fit up can be fast and economical.

Different Tee joint/welds edge preparation

3.1 Plain tee joint is used on ordinary plate thickness up to 0.5mm. If it is possible to weld from both sides, the joint will withstand high load conditions. The single fillet welded tee joint will not withstand bending action at the root of the weld and should be used with caution. There is no preparation cost. 3.2 Single bevel tee joint can withstand more severe load than plain tee joint. It can be used on plate thickness from 9.5mm to 16mm. If it is possible to weld from one side only, care must be taken so that full penetration to the root weld is obtained and bending action will not result in failure. Cost of preparation is greater than plain tee joint. 3.3 Double bevel tee joint is used for heavy plate thickness up to 25.40mm. Welding is done from both sides of the plate. It is used for severe loads. Good root penetration is necessary. Joint preparation is expensive. 3.4 Single J tee joint is used for more severe load condition. Generally used on plate 25.40mm or heavier if welding is to be done from one side. Efficiency of joint can be increased materially by putting in bead in opposite J. This will reduce the tendency of failure at the root as a result of load at this point. SAQ-1: What are the types of fillet joints?

Try Assessment 1: Question # 1 a. Lap joint- is frequently used in all kinds of work, which may be single- fillet lap joint or double fillet lap joint. The single fillet lap joint is not as strong as the double fillet lap join which is more often used on ordinary work. Single fillet lap joint should not be used if root of joint is to be subjected to bending. This type of joint should never replace the butt joint on works under severe load. b. Corner joint-is a weld joint formed when two joint members are positioned at an approximate 90 degrees angle with the weld joint at the outside of the joint members. Heavier plate can be welded if the load is not severe and there is no bending action at the root of the weld. No preparation is needed and fit up is usually simple. Half open corner joint may be u sed on 12 gauges up to 4.5mm. Full open joint can be cut absolutely square and suitable clamping and holding devices are needed to facilitate fit up. c. Tee Joint-is a welding joint at the junction of two parts located approximately at right angles to each other in the form of a T. In terms of welding, thicker metals at the edge to be joined should be bevelled.

Activity 2: 1. Flat position

3. Vertical position

4. Overhead Position

Try Assessment 1 1. A fillet weld is type of weld that has a roughly trian gular cross section. A fillet weld typically requires less joint preparation than a groove weld, making it a very cost-effective joining method and therefore considerably more abundant in the welding industry. A fillet weld joins two surfaces at an approximate right angle to each other. 2. The types of fillet welds are 1. Full fillet weld, 2. Staggered intermittent fillet weld, and 3. Chain Intermittent fillet weld. 3. The type of basic filled weld welding positions are: 1. Flat Position or 1F - The easiest type to perform is the flat position. It involves welding on the top side of the joint. In this position, the molten metal is drawn downward into the joint. The result is a faster and easier weld. 2. Horizontal Position or 2F-This is an out of position welding position. It’s a more difficult position compared to the flat position and it requires more skill from the welding operator to do them well. 3. Vertical Position or 3F -In this position, both the plate and the weld lie vertically or almost vertically. When welding vertically, the force of gravity pushes the molten metal downward an d so it has the tendency to pile up. To counteract this, you can use either an upward or downhi ll vertical position. 4. Overhead Position or 4F-In this position, welding is carried from the underside of the - joint. It’s the most complicated and difficult position to work in. In the overhead position, the metal deposited to the joint tends to sag on the plate, resulting in a bead with a higher crown.
