I am looking to reduce a continuous weld to a stitch weld to prevent warping during fabrication. 3) The power source in an arc-welding operation on titanium generates 250 Btu/min, which is transferred to the work surface with heat transfer factor = 0. You mention picking a line - for groove welds you can can pick lines that define the top and bottom of. 8. A staggered weld is simply designed as a fillet weld with a hit and miss so you would call it as 6" on 6" off or as required for the particular fillet weld. Tack welds can be pulled apart and reapplied should the alignment not be correct. As defined in the AWS D1. For DNV and LR, deep fusion welding does not require UT testing, while full penetration welding. n. Melting efficiency in the operation is f2 = 0. 5 (addendum March 2000) which states " roof plates shall be attached to the top angle of the tank with a continuous fillet weld on the top side only" You may want to review the tank design if this connection ask for frangible joint (not exceeding 5mm continuous weld). 5. The following images show cosmetic, fillet, and intermittent fillet welds. These gaps are typically equal to or greater than the size of the weld itself. The power source in a particular welding setup generates 3500W that can be transferred to the work surface with a heat transfer factor = 0. The melting factor in the operation is 0. Compared to Radiographic testing-RT (other volumetric NDT method),. Although you can apply it at different angles, it would be more prominent at 90 degrees. 6. 8. However, many steelwork contractors prefer to switch to partial penetration butt welds with superimposed fillets, or full penetration butt welds , rather than use fillet welds larger than 12 mm. A W200 X 59 steel wide-flange beam is strengthened and stiffened by the addition of 175 mm x 10 mm steel plates that are welded to the fanges of the wide- Mange heam by continuous fillet welds, as shown in Fig. The mode of metal transfer (spray, globular, short-circuiting, pulsed-arc) is varied by adjusting the amperage and the shielding. 2.
