6 ARC WELD Studs D R A W N A R C W E L D S T U D Standard Fluxed Arc Stud with Ceramic Ferrule Standard Drawn Arc Weld Studs are the preferred choice of all weld studs. This style of stud uses embedded flux and an external shielding ferrule. With these components you can achieve maximum weld penetration and reliability. These weld studs use a process which is robust and provides excellent success under a broad range of conditions. Flux cleanses the atmosphere during the weld preventing impurities from contaminating the weld zone. This flux serves the same purpose as the flux in flux core wire welding or as the shielding gas in standard MIG (GMAW) welding. The ferrule serves 3 main purposes. First, it provides a limited atmosphere to maximize the flux load effectiveness; Second, it vents gasses generated during the welding process; and finally, it contains the molten pool of metal and forms it into a uniform shape. This style of stud also comes in a broad range of configurations. Some configurations include: standard round threaded, no thread, rectangular, square, internally tapped. See the remainder of this section as well as the Specialty Stud section for more examples. While Image tries to stock a good selection of commonly used weld fasteners, the particular one you need may not be in stock. Image produces 60-70% of product to customer specifications. If you don t see what you are looking for then contact your Image sales representative or the Factory directly to achieve a solution that is optimal for your application. 3/8" Mild Steel Stud Welded to 1/8" Hot Rolled Plate Cross Sectional View Showing Weld Penetration 6

7 ARC WELD Studs Standard Drawn Arc Process Description Chuck Stud Ferrule The gun is properly positioned and the main gun spring is partially compressed. The trigger is pressed and the stud lifts off the work. An arc is created and melts the stud and parent material. After the arcing time is completed, the main spring plunges the stud into the molten pool of metal. The gun is withdrawn from the welded stud. The ferrule is broken away and discarded. Weld Stud Specifications MATERIAL: Standard mild steel studs (low carbon C1008-C1018) conform to ASTM A307 & ASTM F568. Stainless Steel Studs (302/302 HQ/304 & 305) conform to ASTM F593 & F738. Other materials including aluminum, medium carbon steel, stainless 316 along with specialty steels, HY80 and HY100 are available on special order. For additional information contact your Image Sales Representative or the Factory directly. THREAD: Standard thread is UNC-2A for U.S. threads and 6g for metric threads. This is important when gauging threads during inspection. Different thread specifications can be manufactured on a custom basis. PLATING/COATING: Weld studs can be plated with a variety of materials including zinc (according to OSHA standards), nickel, dichromat etc. Other plating or finishing requirements can be accommodated. PLEASE NOTE: The welding flux is not plated to prevent weld contamination, i.e. fluxing is done after plating. ANNEALING: Upon request, stud ductility can be increased by annealing to Rockwell B, 75 max. for low carbon steel and Rockwell B, 90 max. for stainless steel. MECHANICAL PROPERTIES: All torque, tensile and shear values are calculated values based on a minimum material tensile specification. Typically, the material used exceeds these specifications. The calculated minimums are provided as a reference. All torque and tensile values are calculated based on working limits. These working limits are designed for bolts which are to be reused instead of bolts which are for permanent installation. An additional 25% safety factor has been added to achieve the working level. The tensile and torque values are for tensile loading only. The shear values are for shear loading only. These values will be different for combined tensile and shear stresses.

The primary advantage of a Pitch Stud versus a Full Thread Stud is in shear value. The Pitch Stud will have a higher shear value than the same size Full Thread Stud. This is due to the slightly larger base diameter of a Pitch Stud. However, since a Pitch Stud is not fully threaded it may not be appropriate for your specific application. A Pitch Stud is best suited when there is a mating part that covers the unthreaded portion of the weld stud..12" STANDARD ACCESSORIES C31 G31 FTS20 C37 G37 FTS20 37P.12".19".19" C50 C62 C75 G50 G62 G75 FTS20 FTM20 FTM20 50P 62P 75P 8

The threads on a Full Thread Stud run the full length of the fastener (hence full thread). This simplifies many mating part concerns and is a favorite of engineering. A Pitch Stud requires that the mating part(s) cover the unthreaded portion of the fastener. Also, a Pitch Stud is marginally stronger in shear than a Full Thread Stud due to the slightly larger diameter in the shear area. 10

This style of stud is frequently used when the mating part tolerances are very tight and can not accomodate the extra fillet diameter of a Pitch or Full Thread Stud. Because of the extra processing involved, a Reduced Base Stud is typically more expensive than an equivalent Pitch or Full Thread Stud. Also, because the base is reduced in diameter the mechanical properties of the fastener are lower than for the equivalent thread size in either Pitch or Full Thread Studs. 16

This gives a stud maximum shear capabilities for its diameter. A full base does not offer any increase in tensile since the threads dictate the minimum affected stress area. These studs are frequently used in applications where maximum shear is important and maximum fastener size is limited. Due to required manufacturing processes, a Full Base Stud will be more expensive than equivalent size Pitch and Full Thread Studs. 18

The primary advantage of a Pitch Stud versus a Full Thread Stud is in shear value. The Pitch Stud will have a higher shear value than the same size Full Thread Stud. This is due to the slightly larger base diameter of a Pitch Stud. However, since a Pitch Stud is not fully threaded it may not be appropriate for your specific application. A Pitch Stud is best suited when there is a mating part that covers the unthreaded portion of the weld stud. 28

The threads on a Full Thread Stud run the full length of the fastener (hence full thread). This simplifies many mating part concerns and is a favorite of engineering. A Pitch Stud requires that the mating part(s) cover the unthreaded portion of the fastener. Also, a Pitch Stud is marginally stronger in shear than a Full Thread Stud due to the slightly larger diameter in the shear area. 29

This style of stud is frequently used when the mating part tolerances are very tight and can not accomodate the extra fillet diameter of a Pitch or Full Thread Stud. Because of the extra processing involved, a Reduced Base Stud is typically more expensive than an equivalent Pitch or Full Thread Stud. Also, because the base is reduced in diameter the mechanical properties of the fastener are lower than for the equivalent thread size in either Pitch or Full Thread Studs. 32

Shoulder Base Studs are made to order. If you are thinking of using a Shoulder Base Stud, consider a Collar Stud. A Collar Stud will provide a similar boss / land area as a Shoulder Base Stud at a cost / delivery time savings. The fundamental difference between a Shoulder Base Stud and a Collar Stud is that the base of a Shoulder Base Stud can handle more shear than the base of a Collar Stud for a given thread size. However, a Collar Stud can be welded to a thinner gage of metal than a Shoulder Base Stud for a given thread size. 35

36 CD WELD Studs C D W E L D S T U D Standard Capacitor Discharge Stud The Capacitor Discharge or CD Stud Welding process is extremely fast. Weld times of.006 seconds can be achieved by using the gap process. Because of the short weld times, no flux or shielding gas is required to achieve good integrity welds. Short weld times are good for welding onto thin sheet metal. Good welds can be achieved on sheet as thin as 0.015" (0.4mm). On thicker gauges, excellent cosmetic results can be achieved with minimal reverse side marking. Such low heat is generated during the short weld times that reverse sides can be pre-painted without damage to the paint. Because of the short weld times, penetration is minimal. There is no porosity or weld contamination, but the penetration is only a few thousands. Therefore, CD welds are excellent on thin gauges and / or in cosmetic applications, but a process with longer weld times should be used for superior integrity. Critical factors impacting CD weld results are weld voltage (set by the operator on the power supply) and ignition tip length (controlled during the manufacturing process by Image Industries). If the weld voltage is not sufficient, there will not be enough heat generated to successfully fuse the stud onto the base material. If the ignition tip, which controls arc length, is not long enough, the weld will not have enough penetration to form a complete bond. A common welding problem with CD Studs is to use a dimple or witness mark to locate stud position. The CD Stud ignition tip fits into the dimple. This effectively shortens the ignition tip length and results in shorter arc lengths which translates into less heat into the weld. The Gap CD Welding Process welds studs faster than the Contact CD Process. Gap weld times can range from seconds to seconds while contact times range from about seconds to seconds. While this time difference is not critical from a production rate standpoint, it is critical when welding non ferrous alloys such as aluminum or brass. Because non ferrous alloys dissipate heat exceptionally well, a slow CD weld can melt and solidify the base metal before the face of the stud has made contact with the base metal. Therefore, the Gap Process, which has faster stud velocities; ensures the stud contacts the base metal before the weld pool has solidified. The downside to Gap CD is that it requires more sophisticated / expensive equipment. 1/4" Mild Steel CD Stud Welded to 1/8" Hot Rolled Plate Cross Sectional View Showing Weld Penetration 36

37 CD WELD Studs CD & CD Gap Welding Process Description Initial Gap CD Stud is positioned against work on the timing or ignition tip, the gun mechanisms are compressed. Initial Gap is set in the welding gun. The gun is positioned over the target. The gun begins to drive the stud into the base metal Contact CD Welding Process The Trigger is pulled, the timing tip vaporizes and an arc is formed. This arc melts the bottom of the stud and top of the base metal. Gap CD Welding Process The gun trigger is pulled and the gun's mechanism accelerates towards the weld site. The gun continues to drive the stud toward the base metal Complete fusion Upon contact with the base metal, the ignition tip vaporizes and an arc is formed. This arc melts the bottom of the stud and top of the base metal. At the end of travel, the power source is completely discharged and the stud has formed a complete bond with the base material. Complete fusion At the end of travel, the power source is completely discharged and the stud has formed a complete bond with the base material. Weld Stud Specifications MATERIAL: Standard Mild Steel Studs (low carbon ) conform to ASTM A307 & ASTM F568. Stainless Steel Studs (302/302 HQ/304) conform to ASTM F593 & F738. Aluminum Studs are manufactured from 5356 alloy. Other materials are available on special order. To discuss your needs and match a process to those needs, or alternate methods for locating CD Studs, consult your Image Sales Representative or the Factory directly. C D W E L D S T U D THREAD: Standard thread is UNC-2A for U.S. threads and 6g for metric threads. This is important when gaging threads during inspection. Different thread specifications can be manufactured on a custom basis. PLATING/COATING: Carbon Steel CD Studs are typically furnished with a copper flash plating for better conductivity and some corrosion resistance. ANNEALING: Upon request, stud ductility can be increased by annealing to 75 Rockwell B for low carbon steel and 90 Rockwell B for stainless steel. MECHANICAL PROPERTIES: All torque, tensile and shear values are calculated values based on a minimum material tensile specification. Typically, the material used exceeds these specifications. The calculated minimums are provided as a reference. All torque and tensile values are calculated based on working limits. These working limits are designed for bolts which are to be reused instead of bolts which are for permanent installation. An additional 25% safety factor has been added to achieve the working level. The tensile and torque values are for tensile loading only. The shear values are for shear loading only. These values will be different for combined tensile and shear stresses. 37

42 AP WELD Studs A P W E L D S T U D Standard Advanced Process Stud Advanced Process or AP Weld Studs are so named because they can be used with a variety of stud welding processes. These processes include; Drawn Arc, Capacitor Discharge, Short Cycle Drawn Arc, Gas Metal Arc and Short Cycle Gas Metal Arc. Because none of these processes use a flux load like standard Drawn Arc they do not achieve as deep a weld penetration. Also, the weld penetration of these studs varies greatly from one process to another. For instance, using an AP Stud with a Capacitive Discharge Process will only achieve a few thousands penetration; while the same AP Stud using the Gas Metal Arc Process will achieve penetrations approaching that of flux loaded studs. Additionally, various gas mixes will impact spatter and penetration. reductions after welding vary with process selection. Capacitor Discharge length reduction is negligible. Short Cycle & Short Cycle Gas Metal Arc length reduction is approximately 0.04 inches (1mm). Gas Metal Arc is approximately inches (3mm) depending on the shielding gas selected. None of the AP Processes utilize a ceramic shielding ferrule. This is an advantage from a material handling perspective. However, since the weld fillet is not contained, fillet formation is somewhat random and unpredictable. Flange concentricity, controlled in the stud manufacturing process, is one factor which can aid in uniform fillets. Also, these processes are susceptible to a phenomenon known as arc blow. This is a phenomena where the molten pool of metal flows away from the strongest ground location. This can be compensated for with multiple ground points. Overall this style stud is economical and flexible on process selection. With a few caveats it can fullfil the requirements of many applications. 42
