BODY SEAL, SEALING DIAGRAM

Scheme 23

1. Weatherstrip

When replacing sheet metal parts, the joints between the different sheet metal parts shall be sealed according to illustration.

Use: Seal, 1161767

2. Spray sealant

The putty can be applied in a bead, be sprayed in a thin layer or brushed on with a paintbrush.

Use: Spray sealant, 1161651

When applying in a bead this type of putty is very difficult to rework since the putty has a loose texture. The putty restores the vehicle to production-like version after body work.

Scheme 24

Use at visible joints, such as the joint between the roof sill and roof panel.

Use: Seal, 3M 08115

3M 08115 is not approved as a substitute for Volvo bodywork adhesive.

If 3M 08115 is not available, then a sealing compound with the following properties shall be used

1. flows out without running
2. has the correct hardness
3. can be sanded when hardened
4. has the correct flexibility.

Scheme 25

Soundproofing foam is installed in hollow spaces to counteract propagation of sound in the body. There are two types of approved soundproofing foam

Volvo's soundproofing foam consists of a wax-treated cylinder 50x50 mm. It can be compressed for installation between metal parts. Several cylinders can be used if one is not enough.

Use: Insulation foam, 68117640

3M ' 2-component foam starts to foam when the components are mixed. The foam is suitable for filling of larger hollow spaces and can be applied between the roof bow and the roof panel. Follow the supplier's instructions for application.

Use: 2-component foam, 3M 08463

Scheme 27

see 9814075

Use: Cavity protection, 1161682

Insert the hose in the cavity and spray at the same time as the hose is pulled out slowly.

For body repairs, the marked areas in the illustrations shall be rustproofed with extra thoroughly. For example, this applies to welded joints and areas that have been reworked in another way.

Scheme 28

see 9814076

Use: Stone-chip protection, 1161299

Apply stonechip protection to the areas of the vehicle marked in blue in the illustration.

Scheme 29

see 9814076

Use: Underbody protection, 1161298

Apply underbody protection to the areas of the vehicle marked in blue in the illustration.

Note. HSS (High Strength Steel) is a general term for steel material within a specific strength range.

Note. The vehicles are built of different steel material, partly to optimize the body (impact safety, rigidity, fuel economy, etc.) and partly to make it as repair-friendly as possible. The steel material is classified into four different groups based on tensile strength, which is the force required to plastically deform the material.

1. Mild steel (MS). Trade steel with highest tensile strength of 180 MPa.
2. High tensile strength steels (HS). Steel with a tensile strength between 180 - 280 MPa.
3. Very high tensile strength steels (VHS). Steel with a tensile strength between 280 - 380 MPa.
4. Extra high tensile strength steels (EHS). Steel with a tensile strength between 380 - 800 MPa.
5. Ultra High Strength steel (UHS). Steel with a tensile strength of more than 800 MPa.

Mild Steel - This category of steel is used where use of a stronger steel is not necessary.

High Strength Steel - There are three main types of steel in this category

1. Phosphorus-alloyed steel obtains is increase in strength with the help of the alloy matter phosphorus.
2. HSLA steel (High Strength Low Alloy) is a low alloy steel in which the steel obtains its increase in strength with the help of the alloy matter Vanadium, Niobium or Titanium.
3. DP steel (Dual Phase) obtains its increase in strength through the thermal treatment that the steel undergoes during manufacture. Then a two-phase structure of ferrite (iron) and martensite (carbon) is formed. This steel loses its strength when exposed to temperatures above 300°C.

Extra High Strength Steel - This category contains both HSLA and DP steel, but the strength has been further increased with greater additions of alloy substances.

Ultra High Strength Steel - There are two main types of steel in this category

1. DP-steel. Here, strength has been further increased with an advanced manufacturing process and with higher additives of alloy substances.
2. BORON steel obtains its strength through the use of the basic element boron and contains relatively large amounts of carbon. The plate profiles are formed heated between the die cutter and die cushion, where the material is also hardened. Due to its extremely high strength, it is difficult to straighten with good results. Grinding or plasma cutting is recommended when replacing BORON steel components. BORON steel welds well. It is not possible to galvanized BORON steel during the production process. It is therefore very important to rustproof these components extra thoroughly.

WELDING, GENERAL

Note. The illustrations in this service information are used for different model years and/or models. Some variation may occur. However, the essential information in the illustrations is always correct.

Volvo bodies are manufactured to the highest quality. All bodywork repairs must therefore take place following the same principles. Use light tools. Take care of the surface coating, electro dip (ED) and phosphating.

Always use welding primer between welded panel flanges.

PRIOR TO WELDING

RESISTANCE SPOT WELDING

Resistance spot welding must primarily be used if the capacity of the welding equipment is matched to panel thickness. When carrying out resistance spot welding, grind down to bare metal.

Clean the surfaces with Scotch-Brite or similar to minimize zinc and phosphating damage. Apply welding primer between the panels.

Note. Always test weld in accordance with the method below. Always set the weld according to panel quality

MAG WELDING

Punch replacement part for plug welding.

Select size of hole for plug welding according to the following panel thicknesses

8 mm for thicknesses less than 2.5 mm

10 mm or more for thicknesses above 2.5 mm.

Scheme 36

Test weld several test pieces. Break the panels apart and measure the size of the welding lens diameter (A), see illustration.

Scheme 37

Note. Use welding primer on all internal flanges.

Add filling primer if there is grinding damage.

Scheme 38

Grind down the plug weld.
