2. Precautions when repairing body frame parts

2. Precautions when repairing body frame parts (including crush box)

(A) prohibition of heat repair for body

(A) prohibition of heat repair for body frame parts

(1) rustproof high strength steel sheets are used for the body frame. Therefore, if these parts are heat repaired using an acetylene torch or equivalent, the crystalline structure changes, causing the strength of the steel sheets to decrease. Also, the zinc corting which is used to protect the body from rust will be damaged. This causes the surface of the steel sheets to become oxidized, which reduces their ability to resist rust.

(B) when to replace frame parts

(B) when to replace frame parts

Notice

: replace frame parts that have kinks. Hint: what is kink? A deformatision bon a steel sheet that cannot be returned to its original shape by pulling or hammering due to the deformation angle being sharp.

(C) repair of door side impact beam is

(C) repair of door side impact beam is prohibited

(1) the impact beam is desined so that it performs at 100% in its original shape.

However, if the impact beam is repaired, its performance may not be the same as before the accident.

Parts ehich are prohibited to be repaired: door side impact beam

(D) repair of bumper reinforcement is

(D) repair of bumper reinforcement is prohibited

(B) anti-rust treatment before welding

(B) anti-rust treatment before welding

(1) apply welding primer to the contact surfaces of the welding areas to protect them from rust.

Notice

: do not apply welding primer outside of the contact surfaces.

(C) making holes for plug welding

(C) making holes for plug welding

(1) for areas where a spot welder cannot be used, use a puncher or drill to make holes for plug welding.

(D) welding precautions

(D) welding precautions

(1) the number of welding spots should be as follows.

Spot weld: 1.3 X no. Of manufacturers spots plug weld: more than no. Of manufacturers plugs (2) spot weld locations avoid welding over previously welded areas.

8. Precautions for resin parts

(a) plastic properties chart

(1) when repairing, some parts may be deformed by the heat. Therefore, confirm the properties of the platic parts, and remove parts beforehand as necessary.

* Temperatures higher than those listed here may result in material

* Temperatures higher than those listed here may result in material deformation during repair.
