Any fitting or fabrication work should be carried out in accordance with applicable site safety standards, ensuring use of approved hard hats, eye protection, steel-toed shoes and protective gloves. Always use a soft faced hammer when performing the work as described in these instructions.
This practice is suitable for Chocky bars and Wafer Strips only.
NOTE: For severe curves with a radius of less than 12”, or inside curves, it is advisable to notch the mild steel backing plate opposite the ‘V’ to assist forming. (Fig A) The Chocky Bar may crack during bending. This is normal.
Clean the surface to which chocky bar will be welded
Tack weld one end of the chocky bar (as per the welding procedure) in at least 3 places by 0.59” minimum length per weld.
Outside Curves: Hammer down welded end of bar with a soft face hammer to bend bar to match mating radius
Inside curves: Starting in the center strike bar with a soft face hammer to bend bar to match mating radius
Stitch weld, laying 1.97” maximum length on each run, alternating ends or sides to minimize heat input
