Repair of bent plates, channel sections etc.

CAUTION

If the repair is still defective, it may be repeated two more times.

Painting.

(a)

Refer to MIL-C-53072B (ME) paragraph 3.6.

Repair of bent plates, channel sections etc.

CAUTION

Cold forming of aluminum alloy component plates is not permitted.

NOTE

This procedure is applicable to the straightening of plates where both sides of the

plate are accessible.

The steel components described within this section may be cold worked to remove any

deformation.

For aluminum, local heat treatment is to be applied to the area of the plate that is required to be

straightened, followed by standard panel beating of that area.

If the distortion of either steel or aluminum components is too severe to be beaten out, it is

permissible to cut through the center line sufficiently to allow straightening and to rejoin the cut by

welding after completion of the heat treatment and panel beating. The following repair procedure

(fig. 2-2) applies to a severely distorted plate and should be interpreted appropriately for less

severe distortion.

WARNING

THIS TYPE OF REPAIR IS ONLY TO BE CARRIED OUT ON THE COMPONENTS

COVERED IN SECTION 5. WELD REPAIRS ON UNAUTHORISED COMPONENTS

CAN LEAD TO DEATH OR SEVERE INJURY.

CAUTION

Weld repair should only be performed when replacement parts are not available. The

defective component should be replaced at the earliest opportunity.
