Welding Procedure – H-Pile
The one-piece point is made to fit each nominal size “H” Pile. It attaches with a weld along the outside of each flange. The point is slipped on the pile and a vertical weld made along each flange. This must be full width of the flange. Welding only the ends overstresses the vulnerable corners. .
When preparing for attachment of the point to the pile stack the H piles so the ends are accessible with the flanges vertical. (Stack the H-sections with the webs horizontal and the ends accessible to the welder. Alternate piles can be extended beyond the stack in each direction to achieve this.) The cast steel point can then be attached by holding it tight against the H and then making a simple weld along each side. By stacking the piles in this manner both sides may be welded, without having to turn the pile.
NOTE: It is suggested that this weld should be a minimum of 5/16 in. and increased when attaching to material of more then 0.55 inch metal thickness.
A good weld is essential to hold the point reinforcement in position when it strikes tough obstructions or sloping rock at one edge only. Beveling across each flange of the H assures a base for a good weld and is essential for attachment of points.
For field welding of cast-steel points use of AWS E60 or E70 welding rod has been found satisfactory. Again, welding only along the full width of the outside of each flange is adequate. Additional Welding Along The Web Is Not Recommended.
A definite plan should be made for the stacking of these piles with the pre-attached points. To minimize the need for additional handling, one should stack these piles out of the immediate work area, while still keeping them within reaching distance of the crane.
NOTE: (Piles can be dragged either way so point reinforcement may be attached at alternate ends in the stack.)
It is customary to burn a small hole in the flange of the H, about one-fourth of the distance from the top, for a shackle connection for handling. This is by far the safest and quickest means of picking up the H.
