The serviceability of a product or structure utilizing this type of information is and must be the sole responsibility of the builder/user. Many variables beyond the control of The Lincoln Electric Company affect the results obtained in applying this type of information. These variables include, but are not limited to, welding procedure, plate chemistry and temperature, weldment design, fabrication methods and service requirements.
FOR ENGINE powered equipment. 1.a. Turn the engine off before troubleshooting and maintenance work unless the maintenance work requires it to be running. _____________________________________________ 1.b. Operate engines in open, well-ventilated areas or vent the engine exhaust fumes outdoors. 1.c. Do not add the fuel near an open flame welding arc or when the engine is running.
ELECTRIC AND MAGNETIC FIELDS may be dangerous 2.a. Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding current creates EMF fields around welding cables and welding machines 2.b. EMF fields may interfere with some pacemakers, and welders having a pacemaker should consult their physician before welding. 2.c. Exposure to EMF fields in welding may have other health effects which are now not known. 2.d.
ELECTRIC SHOCK can kill. (Cont’d) kneeling or lying, if there is a high risk of unavoidable or accidental contact with the workpiece or ground) use the following equipment: • Semiautomatic DC Constant Voltage (Wire) Welder. • DC Manual (Stick) Welder. • AC Welder with Reduced Voltage Control. 3.c. In semiautomatic or automatic wire welding, the electrode, electrode reel, welding head, nozzle or semiautomatic welding gun are also electrically “hot”. 3.d.
FUMES AND GASES can be dangerous. 5.a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases.When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone.
WELDING SPARKS can cause fire (Cont’d) or explosion. 6.c. When not welding, make certain no part of the electrode circuit is touching the work or ground. Accidental contact can cause overheating and create a fire hazard. 6.d. Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to insure that such procedures will not cause flammable or toxic vapors from substances inside. They can cause an explosion even though they have been “cleaned”.
CYLINDER may explode if damaged. (Cont’d) 7.d. Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder. 7.e. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve. 7.f. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use. 7.g.
b. Faire trés attention de bien s’isoler de la masse quand on soude dans des endroits humides, ou sur un plancher metallique ou des grilles metalliques, principalement dans les positions assis ou couché pour lesquelles une grande partie du corps peut être en contact avec la masse. c. Maintenir le porte-électrode, la pince de masse, le câble de soudage et la machine à souder en bon et sûr état defonctionnement. d. Ne jamais plonger le porte-électrode dans l’eau pour le refroidir. e.
7. Quand on ne soude pas, poser la pince à une endroit isolé de la masse. Un court-circuit accidental peut provoquer un échauffement et un risque d’incendie. 8. S’assurer que la masse est connectée le plus prés possible de la zone de travail qu’il est pratique de le faire. Si on place la masse sur la charpente de la construction ou d’autres endroits éloignés de la zone de travail, on augmente le risque de voir passer le courant de soudage par les chaines de levage, câbles de grue, ou autres circuits.
INTRODUCTION INNERSHIELD® Innershield is an arc welding process that uses a continuously fed wire to supply filler metal to the arc. The wire is not solid, but is tubular. Agents necessary to shield the arc from the surrounding atmosphere are placed inside the tube. No additional shielding is required. Innershield was originally used as a replacement for stick welding. Innershield can provide higher productivity and enhance quality when compared to stick welding.
PRODUCT ADVANTAGES INNERSHIELD FEATURES • Can be used in wind speeds of up to 30 mph without losing mechanical properties. • Gas bottles are unnecessary. • Stiff wire with high column strength. BENEFITS OVER GAS-SHIELDED PROCESSES • Innershield does not require gas shielding. • No external shielding eliminates gas cost. • No shielding gas means no cylinder handling, changeout, and rental saving time and money. • No shielding gas means simpler guns and feeders for lower maintenance costs.
PRODUCT LIMITATIONS SEISMIC APPLICATIONS: Constant voltage (CV) power sources are recommended for use with all Innershield electrodes. NR-211-MP THICKNESS RESTRICTIONS: Wire Diameter Max. Plate Thickness .035”, .045” (0.9, 1.2mm) .068”, 5/64”, 3/32” (1.7, 2.0, 2.4mm) 5/16” (7.9mm) 1/2” (12.7mm) NR-212 is designed to be used on plate up to 3/4” (19.1mm) thick. SINGLE PASS LIMITATIONS Certain FCAW-S electrodes are limited to single pass applications.
PRODUCT LIMITATIONS INTERMIXING When Innershield (FCAW-S) weld deposits are intermixed with weld deposits from other welding processes, a decrease in weld metal Charpy V-notch (CVN) toughness properties may occur. For applications requiring CVN properties, intermix testing with the specific electrodes is recommended to ensure the intermixed weld metal meets the required CVN requirements.
INNERSHIELD GUNS CHOOSE THE PROPER INNERSHIELD GUN Lincoln Innershield Guns Rated Amperage, Duty Cycle and Wire Sizes Innershield Guns Fume Extraction Guns K115-1, -2, -3, -4, -5 Guns with 82° Nozzle 450 Amps at 60% Duty Cycle Wire Size: .068–.120”(1.7-3.0mm) K206 Gun 350 Amps at 60% Duty Cycle Wire Size: .062–3/32"(1.6-2.4mm) K115-8, -10 Guns with 45° Nozzle 450 Amps at 60% Duty Cycle Wire Size: .068–.120”(1.7-3.0mm) K309 Gun 250 Amps at 60% Duty Cycle Wire Size:.062–3/32"(1.6-2.
WELDING PREPARATIONS PREPARE THE WORK Clean the joint by removing excessive scale, rust, moisture, paint, oil and grease from the surface. As with all welding applications, joint cleanliness is necessary to avoid porosity and to attain the travel speeds indicated in the procedures. Tack weld with Innershield wire or Fleetweld® 35LS, Jetweld® LH-70 or Jetweld 2 manual stick electrodes. If other electrodes are used, Innershield slag removal may be difficult in the area of the tacks.
WELDING TECHNIQUES SET THE CONTACT TIP TO WORK DISTANCE (CTWD) WARNING: When inching, the wire is always electrically “hot” to ground, except on wire feeders with a “cold inch” feature. CTWD is measured from the end of the contact tip to the work. Maintain this length within ±1/8” (3.2mm.) for CTWD ≤1” (25 mm) or within ±1/4” (6.4 mm) for CTWD >1” (25 mm) during welding. To obtain the proper CTWD when using an insulated guide: 1. Remove the insulated guide from the end of the gun tube. 2.
WELDING TECHNIQUES SET THE WIRE FEED SPEED Adjust the wire feed speed using the WFS control on the wire feeder. Set to the suggested procedures. See pages 30-39. The approximate amperage corresponding to each WFS at the specified CTWD is also listed in the table. Amperage depends on wire feed speed and CTWD. If the CTWD is shortened, amperage will increase.
WELDING TECHNIQUES LOADING 13-14 LB. (5.9-6.5 kg) COILS ON A 2” (50mm) SPINDLE 1. Remove the locking collar and the cover plate from K435 spindle adapter. 3. Unpack the 14 lb. (6.4kg) coil of wire. Be sure not to bend the side tabs of the coil liner. Straighten any tabs that may have been bent. 4. Remove the start end of the coil, cut off the bent end, straighten the first six inches. Be sure the cut end of the wire is round and burr free before the new coil into the drive rolls.
WELDING TECHNIQUES HANDLING POOR FITUP Innershield bridges gaps better than most welding processes. When using NS-3M at 3” (76mm) CTWD, temporarily increasing the visible CTWD to as much as 3-1/4” (83mm) helps reduce penetration and burnthrough to bridge gaps. Poor fitup may require a small, temporary increase in visible CTWD or a reduction in WFS setting. USE A DRAG TECHNIQUE Tilt the gun back away from the weld puddle in the direction of travel about the same as required in stick electrode welding.
WELDING TECHNIQUES MAKING VERTICAL UP WELDS Use 5/64” (2.0mm) size and less. NR-202 NR-203MP NR-211-MP NR-232 NR-203M NR-203 Nickel (1%) NR-212 NR-233 Smaller sizes, 5/64" and less are recommended for all position welding. When welding out-of-position, don’t whip, break the arc, move out of the puddle or move too fast in any direction. Use WFS in the low portion of the range. General techniques are illustrated below.
WELDING TECHNIQUES Vertical Up Fillet and Lap Welds 1. Make larger welds with the following techniques: a. On 1/4” (6mm) welds, a short side-to-side motion is usually sufficient. b. On larger welds, use a triangular weave (see number 1 in the sketch below) with a distinct hesitation at the outer edges for the first pass. c. Use a side-to-side weave (see number 2 in the sketch below) similar to that used for butt welds on the second and later passes.
WELDING TECHNIQUES WORKING WITH NS-3M To calculate electrical stickout, subtract 1/4” from CTWD. .120" (3.0mm) NS-3M When using the long CTWD of 3” to 4” (75 to 100mm), the long length of wire beyond the contact tip has greater electrical resistance. Because of the greater resistance, the wire is heated to a higher temperature so it melts more rapidly in the arc to increase deposition rates and lower weld cost. Using a long CTWD reduces penetration and makes starts more difficult.
OPERATING GUIDE Well made Innershield welds have excellent appearance. TROUBLESHOOTING To Eliminate Porosity (In order of importance) 1. Clean the joint from moisture, rust, oil, paint and other contaminants 2. Decrease voltage 3. Increase CTWD 4. Increase WFS 5. Decrease drag angle 6. Decrease travel speed To Eliminate a Ropey Convex Bead (In order of importance) 1. 2. 3. 4. 5.
OPERATING GUIDE To Minimize Arc Blow (In order of importance) Arc blow occurs when thr arc stream does not folow the shortest path between the electrode and the workpiece. 1. Move work connection locations 2. Decrease drag angle 3. Increase CTWD 4. Decrease WFS and voltage 5. Decrease travel speed To Eliminate Stubbing (In order of importance) Stubbing occurs when the wire drives through the molten puddle and hits the bottom plate tending to push the gun up. 1. Increase voltage 2. Decrease WFS 3.
OPERATING GUIDE 3. Increasing WFS also increases the maximum voltage which can be used without porosity. Lowering the WFS requires lowering the voltage to avoid porosity. As the WFS is increased, the arc voltage must also be increased to maintain proper bead shape. Travel Speed If arc voltage, WFS and CTWD are held constant, travel speed variations have the following major effects: 1. Too high a travel speed increases the convexity of the bead and causes uneven edges. 2.
STORING INNERSHIELD ELECTRODES In general, Innershield electrodes will produce weld deposits which achieve diffusible hydrogen levels below 16 ml per 100 grams deposited metal. These products, like other products which produce deposits low in diffusible hydrogen, must be protected from exposure to the atmosphere in order to; (a) maintain hydrogen levels as low as possible (b) prevent porosity during welding (c) prevent rusting of the product.
STORING INNERSHIELD ELECTRODES Innershield Products Used for Applications Requiring More Restrictive Hydrogen Control (-H Electrodes) The AWS specifications for flux-cored electrodes, AWS A5.20 and A5.29, state that “Flux-cored arc welding is generally considered to be a low hydrogen welding process”. Further, these specifications make available optional supplemental designators for maximum diffusible hydrogen levels of 4, 8 and 16 ml per 100 grams of deposited weld metal.
