CHAPTER 6 WELDED CONNECTIONS 6 1 INTRODUCTORY CONCEPTS

LIZARD is a portable programmable welding carriage designed to produce high quality welds using MIG/MAG welding torches Friction drive and control loop feedback mechanism provide speed stabilization in all positions A very important optional feature of LIZARD is oscillation attachment Figure 5 is an example of a chart for selecting the proper welding cable size Other charts are available from cable manufacturers and welding reference books As an example let’s assume you have a amp power source at 60% duty cycle and need a total combined length of electrode plus work cables of feet The carriage follows the weld joint using guide wheels that adjust to allow the unit to drive itself against the workpiece Ideal for use with ESAB& 39 s GMAW power sources and with A2 A6 PEK Controller is a universal welding tractor for submerged arc welding SAW and gas metal arc welding GMAW applications Rotary Welder Rotary welding machines are systems designed to weld circular components with high through put These machines offer both single or multiple torches to weld both small and large surface areas The BANCROFT WELDA ROUND family of automated welders are versatile and durable production tools designed to weld a broad range of parts Imperial Grades IBF/IN2 PSI Metric Classes MPA N/MM2 L9 PSI HIGH TENSILE CLASS 12 9 1 MPA HIGH TENSILE SAE GRADE 8 PSI HIGH TENSILE7 0 Design for Welding Stainless Steels 14 8 0 Selection of Filler Metals 14 9 0 Selection of a Welding Process 18 9 1 Shielded Metal Arc Welding 9 2 Submerged Arc Welding 9 3 Gas Metal Arc Welding 9 4 Flux Cored Arc Welding 9 5 Gas Tungsten Arc Welding 10 0 Procedures for WeldingCable manufacturers or welding textbooks can provide recommended gauge sizes for welding applications End users select the welding power supply’s rated output duty cycle and the circuit length to determine the correct cable size Table 1 is an example of a welding cable sizing chart Welding Machine Rating Amperes Duty Cycle % Lengthsroot opening during root pass welding Fillet weld sizes as shown on the Welding Procedure Specification shall be used unless otherwise detailed on the engineering drawing Fillet welds shall be made so that they penetrate fully into the root basic standard It covers steel butt welding fittings sizes NPS 1/2 through NPS 48 DN 15 through DN Other ASME/ANSI and MSS standards written to supplement B16 9 are as follows ASME/ANSI Butt welding Ends ASME/ANSI Butt welding short radius elbows and returns

AWG Size Chart Welding cable size is measured by the American Wire Gauge AWG standard AWG sizes will have three numbers for example " 2 AWG /30 " This means that the welding cable has a total cross sectional area of 2 AWG and is made from strands of 30 AWG wire View the AWG reference table below for dimensions and sizing of welding square and hex bolts cap screws carriage bolts plow bolts lag screws studs nuts rivets and others which have been standardized over the years as to type‘ style usage properties dimensions and tolerances These include a vast range of sizes and types stocked by distributors and manufacturers for anAug 21 This rule of thumb assumes the following fillet weld on both sides of the plate fillet weld for the full length of the plate If the plates are different thicknesses the thinner plate thickness Weldcote Metals Mild Steel Electrodes Weldcote Metals Mild Steel Electrodes Lincoln Electric Fleetweld 37 E Stick Electrodes Lincoln Electric Fleetweld 47 E Stick Electrodes ESAB  VacPac 1 Prime Stick Electrodes Layout the tabletop on the ground and marked the four edges where the legs are going to set The marking area should be a minimum of 7 inches off the ends and 3/5 inches away from the side Now cut the legs in proper size The cutting should be reliable because a wrong cut will make your table weaker Using our 10% allowance for overwelding our legs sizes would be ¼ x 1 1 = in So our area = 1/2 x x = 8 square inches We have to weld a total of 76 5 inches per part taken from the example on our previous post Calculating Weight of Weld Metal Required so the total weld volume for each part is 8 x 76 5 = 2 Arc Welding Rod Chart by Type AWS Class Current Type Welding Position Weld Results Mild Steel E E DCR DCR AC F V OH H F V OH H Fast freeze deep penetrating flat beads all purpose welding E E E DCS AC DCR DCS AC DCS AC F V OH H F V OH H F V OH H Fill freeze low penetration for poorThe welding rod By looking at the classification we already know that the welding rod is an all position rod which produces weld beads which can withstand 70 pounds of stress per square inch The last digit – when read in conjunction with the penultimate digit – indicates that it has an iron powder low hydrogen coating so automatic welding carriage KAT® KAT® WELDING AND CUTTING AUTOMATION CARRIAGE FLEXIBLE TRACK Welding Carriage Programmable Low Voltage All Position
