When fillet welds are indicated on both sides of a joint and no general note governing the dimensions of the welds appears on the drawing, the dimensions are indicated as follows: When both welds have. tions is required for the continuous member. In the below example, fillet weld symbol as per ISO 2553 and AWS A2. 7. use intermittent welding in preference to a continuous weld pass. A continuous fillet weld is to be made with a cross-sectional area = 0. The sizes shown in the tables are for 100% efficient double continuous fillet welds and do not include welds with uneven legs or skewed welds. When welding from left to right, maintain a 0 to 15-degree angle tilted towards the direction of travel. For relatively small welds, such as 1â „4- or 5â „16-in fillets, a girder may be positioned with web horizontal to allow welding of both flanges simultaneously. Shape: A butt weld is a type of welding in which the edges of two pieces of metal are brought together and welded, creating a straight, continuous seam. 3. If the weld does not have a dimension the weld will be the continuous length of the joint. For fillet welds, numbers to the left of the symbol indicate the design throat thickness, leg length (leg size), or both design throat thickness and leg length requirements. This is a complete penetration butt weld (compound butt weld placed first followed by a fillet weld). Other defects not listed are mainly those of geometry and include misshapen and incorrectly sized welds, variable cap width and height, weld face roughness, incomplete weld fill and asymmetry of fillet welds. The wire electrode can be a continuous solid or cored wire, or a strip. (1). Other Meanings of CFW. Table 26. 11. 给出一个例子. 1 General. A fillet weld symbol comprises a reference line, an arrow line, the tail and the weld symbol, including the leg size. -the length & centre-to-centre distance also (known as pitch) of the weld increments are different for each type of fillet weld. Seam welds simulated with hex elements to maintain weld root and toe locations. 5 mm. This creates troublesome expectations because I've not seen a technical definition of "ground smooth". 磁粉探伤 magnetic particle inspection. Therefore, that range of fillet welds also requires the engineer to specify the effective throat – not the leg size, as is typical for fillet welds. 2 or the Simplified method given in 4.
