Nissan Armada 2025-2026 Service and Repair Manual: Cut and Butt Joint Weld
Damages that are considered difficult to repair by frame straightening work, such as a deformed crash horn, may be restored by a butt joint weld only if the Service Manual and/or the Body Repair Manual instructs so.
As an example, the butt joint weld procedure for A60 is outlined below.
(1) CRASH HORN (Partial replacement)
(Work after 1st crossmember has been removed.)
Service Joint
Portions to be welded:
A: Inner side rail crash horn (a), inner side rail crash horn (b) and outer side rail crash horn (c)
B: Outer side rail crash horn (c), outer side rail crash horn (d) and inner side rail crash horn (b)
(2) REMOVAL
(a) Scribe a straight line on the outer side rail crash horn and inner side rail crash horn along the hole center as shown in the figure.
(b) Cut off the outer side rail crash horn and inner side rail crash horn along scribed line (A). Do not cut on the hole.
(c) Cut the inner side rail crash horn at 45 mm (1.77 in) backward from cut position of cut line (A) [along line (B)].
After removing the outer panel, dress the area on the inner panel surface with a sander or equivalent.
(3) INSTALLATION
(a) Scribe a straight line on the inner side rail crash horn along the hole center as shown in the figure.
Cut off the inner side rail crash horn along the scribed line.
(b) Scribe a straight line on the outer side rail crash horn along the hole center as shown in the figure.
Cut off the outer side rail crash horn along the scribed line.
(c) Weld part to be butt joint welded and seam-welded corner to corner as shown in the figure.
(4) PRECAUTIONS FOR WELDING
(a) When tack welding is finished, always verify that the crash horn is assembled in the proper dimensions before starting final welding.
(b) Before starting welding work, always remove the components around the weld points. If it is difficult to remove the components, cover them with a fireproof sheet to avoid attachment of any weld spatters and subsequent damage to the surrounding portions.
(c) After painting, spray a sufficient amount of anti-corrosive wax to the rear side of the weld points through the holes near the weld points.
