One of the greatest problems associated with fillet welded joints is achieving the correct weld size in relation to the required leg lengths or throat thickness Fig 4 The designer may calculate the size and allow a & 39 safety factor& 39 so that the weld specified on the fabrication drawing is larger than is required by design considerations Round head carriage bolts are also referred to as round head square neck carriage bolts The dimensions listed above refer only to the standard neck bolts If the dimensions for your requirement are similar but do not correspond directly with those above you may need a round head short neck bolt Once a fillet weld size has been calculated it should be reported on the technical drawing s using the appropriate welding symbols or provided in a technical specification Unfortunately there are many instances in which a fillet weld sizes is unclear on the available drawings not reported or simply the information has been lost Aug 21 fillet weld for the full length of the plate If the plates are different thicknesses the thinner plate thickness should be used An example t joint is shown below with a weld size of 3/8" on 1/2 Lag & Carriage Bolts Carriage Bolts come with a round head and a square neck are commonly used in wood connections The square neck under the round head allows the bolt to set into the hole in the wood to prevent the head from turning Carriage Bolts are generally manufactured to the A Grade A specification in domestic or import Cap Screw Fasteners A cap screw is a screw that has a thick wide head and a flat bottom toward the thread facing site The hex head cap screw is the most common cap screw and is also the most common fastener in construction and machine assembly Our cap screws can be customized to your application and industry Here is my take for double fillet welded joints The effective throat of an equal leg fillet weld is x leg size x 75t = about 53t 2 equal leg fillet welds with leg sizes of 75% the thickness of the base metal would result in a fillet weld with an effective throat of Good dayHigh Strength Grade 8 SteelSquare Neck Carriage Bolts Made from Grade 8 steel these bolts can be used in high stress applications such as valves pumps motors and automotive suspension systems Carriage bolts have a smooth rounded head for a finished look The square neck keeps these bolts from turning when tightening a nut

Portland Bolt manufactures carriage bolts from 1/2″ diameter through 1 1/4″ diameter in most ASTM AASHTO and SAE specifications Special tooling can be created to produce nonstandard head dimensions carriage bolts larger than 1″ in diameter or bolt heads with your company’s name and/or logo This size is called out on the left side of the symbol before the vertical side The size is indicating the leg length of the weld If a single size is called out this is specifying that weld should have equal leg sizes If it is an equal leg fillet weld it is not common to dimension it on the print as shown below for demonstration purpose Fillet h = throat size! Weld Size vs. Throat Size 1/8 75o 3/8 h = plate thickness = weld size Butt h = 0.707 * plate thickness 0.707 * weld size 1/4 Filletweld length as shown in Fig. 1. Fillet weld legs determine fillet weld sizes. Fillet weld sizes are measured by the length of the legs of the largest right triangle that may be inscribed within the fillet weld cross section. Fig. 1 -Fillet weld measurements L: Leg length, S: Fillet weld Size, T: Theoretical throat,For unequal leg fillet welds the “size” of the weld is the leg length of the largest right triangle which can be inscribed within the fillet weld cross section Slip on and Socket Welded Flanges X min = 1 4 T1 or thickness of the Hub whichever is smaller but not less than 1/8 in T1 = minimum pipe wall thickness Size of WeldMar 08 THE WELD SIZE S and E The dimension of welding is important because it’s directly related to the ability of the joint to handle the given load That’s why this element serves to display the weld size required by the design The S Size is mostly used in fillet weld where it represents the leg size of the weld metal type of weld throatand weld size Strength of Structural Welds Part of Table J2 5 AISC 30 • Tack Weld above left A temporary weld used to hold parts in place while more extensive final welds are made • Continuous Weld A weld which extends continuously from one end of a joint to the other • Stitch Weld above right Heavy Duty Ferrules The ferrule helps to shield the arc from the operator it minimizes the atmosphere that the flux must purge the ferrule helps form the molten metal into the fillet while allowing the fillet vents allow weld gases to escape Ferrules are disposable items and as disposable items they are mass manufactured quickly and inexpensively Ferrules are …1/2 in 13 x 8 in Galvanized Carriage Bolt 25 Pack Carriage bolts have a smooth rounded head Carriage bolts have a smooth rounded head with a square neck underneath that locks into wood when tightened Use with a pre drilled hole and secure with a hex nut and washer to prevent spinning
