General Welding Procedures
Jan 31, 2000, Apr 19, 2001
Most Nye products are made from QT100 (T1 Structural) and AR400 (T1Abraision Resistant) Quenched & Tempered steel plate. This extra strong heat-treated alloy steel is heat sensitive and must be treated properly during welding to prevent any unwanted hardening, softening or embrittlement due to hydrogen contamination.
Non heat-treated materials like Mild Steel, 33MAX, and 44W do not require pre-heating, but will not be harmed by it. When in doubt about the type of steel, assume it is Quenched & Tempered and follow these procedures:
- The area to be welded must be completely clean and free from hydrogen sources: dirt, rust, paint, grease and moisture. (Hydrogen contamination is the leading cause of HAZ cracking.)
- Use a temperature indicating crayon or suitable instrument for monitoring material temperature.
- If gouging is required, preheat area to be gouged to 100°C [200°F].
- Completely gouge out all traces of cracked material. (Gouge right through if necessary)
- Grind out all traces of carbon and slag.
- Preheat area to be welded to 150°C [300°F]. (Use welding blankets to keep the heat in)
- Do not allow inter-pass temperature to exceed 260°C [500°F] or fall below 120°C [250°F].
- To prevent hydrogen contamination, use only fresh new electrodes taken from a sealed bag.
- Use several “stringer” beads as opposed to a few wide beads.
- Blend gusset or bracket end welds smoothly into the base plate they are welded to by grinding. Avoid sharp changes in material thickness, taper-off and blend-in welds as opposed to running the welds out past the end of a gusset or perpendicular plate.
- After welding, cover with welding blankets and allow the material to cool slowly in still air.
Suitable (approved) electrodes:
SMAW - Stick Electrodes:
- For all repairs use: E48018 [E7018]
FCAW – Flux Core Wire:
- For basic repairs use: AWS A5.20 CSA W48.5 E70T-1 (ESAB Dual Shield R-70 Ultra)
- For heavy QT sections use: AWS A5.20 CSA W48.5-M E70T-5 (Hobart FabCO85)

Instructions for changing Nye retainer type bushings.
Some Nye Contractors Grapples and Concrete Pulverizers feature special hardened steel or aluminum-bronze pivot bushings that double as retainers. These retainers are designed to keep the Grapple or Pulverizer halves together when the main pin is removed during mounting and dismounting.
IMPORTANT: Read all these instructions before starting.
The bushings should be pressed in from between the bosses of the moving side of the Grapple or Pulverizer with a portable hydraulic jack.
- Lubricate the bushings and get them started by tapping them into the bosses, stepped end first, with a flat plate and a sledge hammer. DO NOT TRY TO DRIVE THE BUSHINGS ALL THE WAY AT THIS TIME.
- Assemble the Grapple or Pulverizer using the main pin and the back pin (or a test shaft) inserted partway in from each side. (Two pins are required to maintain correct boss alignment during bushing installation).
- Using a suitable jack and spacers between, press both bushings in at the same time. The stepped portions of the bushings will protrude past the end of the bosses and should loosely engage the recesses in the fixed half of the Grapple or Pulverizer.
WARNING: The bushings are designed to hold the Grapple or Pulverizer halves together when the main pin is removed. The halves could move apart suddenly causing damage to property, injury or death, if the bushings are damaged or removed.
- Block-up and support the Grapple or Pulverizer as required so both halves are stable and cannot move when the bushings disengage the recesses.
- Install the main pin partway in one side to limit movement of the halves during removal of the bushing on the opposite side.
- Collapse the bushing using heat by running several beads of weld axially along the inside. (the bushing will be destroyed during removal)
- Weld a suitable plate inside the bushing to provide a surface to push against.
- Tap the bushing toward the center from the outside using a sledgehammer and suitable pin pusher.
- Insert the back pin or a spare pin through the bosses before removing the main pin and repeating the process on the other side.

Bucket Lifting Loops
May 7, 2001
Standard Nye bucket loops are provided as a customer convenience and are not rated for any particular load. They are designed for lifting the bucket and for securing the machine or bucket on a float during transport. Nye lifting loops are made of 44W or QT100 steel plate.
Optional “load rated” lifting hooks with spring latches are available at extra cost. These weld-on hooks are rated at 10t, 14t and have a 5:1 safety factor. Special hooks can be specified at the time you order your bucket or can be installed on existing buckets in the field.
Contact our office for price and availability.
Hydraulic Piping Instructions
Jan 31, 2000
Field installation of hydraulic pipes on Nye sticks and stick extensions.
Note: only the ends of pipe clamps need to be welded.
Nye sticks and extensions are made with QT100 Quenched & Tempered steel and must be pre-heated before welding. Please refer to the “General Welding Procedures” before starting.
- Lay the pipes on the stick in the position that provides the most suitable hose routing. (Refer to the attached photo or drawing).
- Mark the clamp locations on the stick with a felt pen.
- Remove the pipes and grind the paint off the stick in the areas to be welded.
- Grind the paint off the ends of the pipe clamps.
- Remount the pipes on the stick.
- Pre-heat the spots where the clamps are to be welded. (Lift the pipe while heating to avoid melting the plastic parts of the clamp)
- Tack-weld the ends of each clamp.
- Disassemble the clamps and remove the pipes and plastic parts.
- Finish welding the clamps. Each clamp should receive a 5 X 25mm long fillet weld on each end. (When re-heating the weld area, apply the heat to the stick, not the clamp. If the clamp is much hotter than the plate it is welded to, it will shrink and crack as it cools).
- Final assemble the pipes and clamps.
- Touch-up with paint as required.
