Introduction
Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.Safety Section
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
Failure to follow all safety guidelines prescribed in this document and by governing authorities and regulatory agencies may result in severe injury or death of personnel or machine damage.
Climbing equipment may be required to access this service point. Refer to the Operation and Maintenance Manual, "Mounting and Dismounting" topic for safety information.
Observe the safe working load limits of all lifting and blocking devices and keep a safe distance from suspended/blocked loads. Personnel may be seriously injured or killed by falling loads.
Welding Specifications and Qualifications
Protect yourself and others; read and understand this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can kill. Read and understand the manufacturer's instruction and your employer's safety practices. Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the general area. Wear correct eye, ear and body protection. Do not touch live electric parts.Refer to the American National Standard Z49.1, "Safety in Welding and Cutting" published by the American Welding Society, 2501 N.W. 7th Street, Miami, Florida 33125: OSHA Safety and Health Standards, 29 CFR 1910, available from U.S. Dept. of Labor, Washington D.C. 20210.
Note: Personal breathing protection should be worn by the personnel that are welding. Personal breathing protection will prevent fumes from entering the lungs of the person that is welding. Use a 237-5181 Respirator for breathing protection.Qualifications
Welders must be qualified for the appropriate type of weld that is being performed. Welders must be qualified for the appropriate position of weld that is being performed. Welders must be qualified for the welding process that is being utilized: Shielded Metal Arc Welding (SMAW) and Flux Cored Arc Welding (FCAW). Refer to Specification ANSI/AWS D1.1 for information that regards qualification requirements. The welders must have used the process at some time within the last 6 months. The welders must complete the process of certification if the welders have not used the welding processes for 6 months.Proper Welding Procedure on Machines and Engines with Electronic Controls
Proper precautions are necessary to prevent damage to electronic controls. When you weld on a machine with electronic controls, use the steps that follow:
Turn off the engine. Put the key start switch in the OFF position.
If the machine has a battery disconnect switch, open the switch. If the machine does not have a battery disconnect switch, disconnect the negative battery cable at the battery.
Attach the clamp for the ground cable as close as possible to the area that is being welded. This process will reduce the likelihood of damage from the welding current to the following components: bearings, hydraulic components, and electrical components. DO NOT weld plates to the frame for grounding/clamping purposes. Use existing blocks, brackets, bosses, and so on, to attach the clamp.Note: Do NOT use electrical components as a ground point for the welder. Do NOT use ground points for electronic components as a ground point for the welder.
Protect the wiring harnesses and machine surfaces from sparks and welding spatter.Area Preparation
The area to be welded shall be clean, dry, and free of the following contaminants:
Oil
Grease
Paint
Dirt
Rust
Any fluids or moistureAll welding shall be conducted on base material heated and maintained at a minimum temperature of 15.6° C (60° F).Note: Heating instructions (preheat, interpass, and postheat) for any specific repair shall override the minimum 15.6° C (60° F) requirement.Note: Heat distortion of the base metal is possible when you weld. Avoid excessive heating of the base metal.Welding Electrodes and Parameters
Flux Cored Welding Electrode for the FCAW Process
Use the Flux Cored Arc Welding (FCAW) with E71T-1 H8 (ANSI/A5.20) welding electrode and the manufacturer's shielding gases that are specified (typically 75% argon and 25% carbon dioxide). The H8 implies that the electrode is designed to provide less than 8 ml/100 g of diffusible hydrogen in the weld deposit. The weld that is deposited by the flux cored welding electrode will have the following minimum mechanical properties:
Table 1
Mechanical Properties from Flux Cored Welding Electrode That Is Classified as "ANSI/AWS A5.20 E71T-1 H8"
Tensile Strength 480 MPa (70000 psi)
Yield Strength 400 MPa (58000 psi)
Elongation 22%
Impact Toughness 27 J @ -18 °C (20 ft lb @ -0 °F) The tables that follow show the recommended parameter ranges for out of position welding in the field for two different flux cored welding electrode diameters.
