How to choose adhesive for metal

Before purchasing the best type of glue, you need to know its scope of application, operating rules and necessary requirements. To determine the requirements that will be imposed on the composition of the adhesive, you need to know what alloy the parts being glued are made of. Study the conditions under which the product will be located and operate: the effects of corrosion, vibration, high humidity, exposure to high temperatures, mechanical stress. Based on the conditions, certain requirements are imposed on metal adhesive:

The industry produces many types of adhesives for gluing metal parts, which are capable of solving various problems. Depending on the environmental conditions and operation of the product, certain types of glue are used.

Choosing a universal glue: what to look for?

When choosing cold welding, in addition to the brand and price, the following parameters are important:

Type of bonded surface.

There are universal adhesives for metal, linoleum and rubber, plastic and concrete. Moreover, the composition allows you to combine materials in any combination, combining into one whole, for example, concrete and wood, rubber and plastic, steel and glass.

Vibration resistance.

Cold metal welding withstands vibration loads, is resistant to aggressive environments and temperature changes. Successfully restores the tightness of radiators, tanks and fuel lines, oil pans and other elements.

Tear resistance.

Restoration of components operating under physical load using universal glue allows the connection to withstand forces of up to 200 N*m. Such welding is indispensable for emergency repair of a car suspension, as it will allow you to independently eliminate the malfunction (broken lever, rod, etc.) and get to a service center or garage without the help of a tow truck.

Heat resistance.

A special type of cold welding that can withstand heating up to 150-250˚C. It is successfully used to restore car mufflers, highways and heating system equipment.

Moisture resistance.

Adhesives of this group are impervious to moisture, and in some cases can be applied even to a wet surface, maintaining high adhesion to it.

Hardening time.

Since cold welding is often used for emergency repairs, setting time is important. The smaller it is, the better.

Advantages

Liquid welding material is advantageous because... does not require experience or special technical skills. The use of cold welding takes place without electric current or heat, therefore it is safe. When the surfaces being bonded interact, no toxic smoke is generated, there is no bright light, and no special protective equipment is required for operation. The highly plastic adhesive substance is very mobile, you can take it with you and use it at any time. In this case, preparation is minimal.

The composition is characterized by high corrosion and temperature resistance, electrical conductivity, and non-toxicity. The process of joining surfaces is fast, the material dries in the first minutes, proceeds without deformation, due to which the appearance is preserved and impurities do not get into the seam.

Top 5. "CONTACT"

Rating (2021): 4.21

11 reviews taken into account from resources: Otzovik, YandexMarket

Eliminates emergency leaks without drying Thanks to its high adhesive ability, the universal cold welding “Contact” can quickly eliminate a leak in a pipe, oil pan or gas tank without first drying the damaged area.

• Characteristics

  Average price: 239 rub.

• Country Russia
• Weight: 50 g
• Curing time: 180 min.
• Temperature resistance: -40…+150˚C
• Number of components: 2

The universal adhesive has proven itself excellent in restoration and gluing of various metals, glass, ceramics, plastic, and wood. Easily takes a given shape and sets quickly. For cold welding, stopping a leak in a water pipe or gas tank is not a problem. At the same time, the glue performs its task by working with a wet surface. Due to its high adhesion, “Contact” perfectly seals the most inaccessible places. The plasticity of the compound prepared for work decreases sharply after 3-5 minutes, so you need to work with it quickly. Treating the base during application (cleaning and degreasing) increases the reliability of the connection, however, during emergency repairs this is not always convenient.

Advantages and disadvantages

• Hardens quickly
• High adhesion
• Solvent resistance

• Foundation preparation required

Which is the best selection criteria?

When choosing an adhesive, you need to focus on the desired functionality. The type and specialization of the required welding depends on the type of raw material being glued. Repairs must be carried out in strict accordance with the manufacturer's recommendations. Therefore, for a specific problem, you need to select the appropriate composition; in unsuitable conditions, the seam will not hold.

Temperature

Thermal stability indicators are important for items subject to intense heating. In everyday life, this applies to dishes. The limit of most universal welding substances does not exceed +275 °C. When using it to seal holes in pots and pans, oven accessories (baking trays), you should take into account the maximum heating point. High-temperature products that can perform functions at +1000 °C and above are considered more durable. They add elements that increase viscosity, so that adhesion is not lost.

Sealants

Cold welding work is carried out to restore the integrity of the object being repaired. Therefore, it is important how airtight the defect is plugged. Types of welding grades specialized for sealing are water resistant. They are not destroyed by constant water pressure and erosion, do not allow water to pass through, and are suitable for repairing water pipes. In cars, sealants are applied to cracks and holes in radiators, thereby preventing overheating of the vehicle and maintaining the circulation of coolant.

Compositions for cars

Adhesive materials intended for vehicles have unique characteristics:

• high tensile strength (tensile stress);
• resistance to vibration, shock, mechanical pressure;
• immunity to solvents and oils;
• maintaining stability under sudden temperature changes.

Recommendations for use

Despite the fact that the process of using cold welding is quite simple, you should still know some of the features of its use.

Drying period

It is different for each type and even for each brand, but it usually dries completely within 24 hours. However, there is also such a concept as “pre-drying” - it means that the substance has already created the final form, is no longer susceptible to deformation, but has not yet achieved a stable connection with the processed object. In this position, the applied seam is still vulnerable, so you should not subject the treated object to unnecessary stress. “Pre-drying” usually occurs in the first 5-20 minutes after application, so this period is quite enough for the user to form the seam itself. Some brands of cold welding reach final drying in half a day, but professionals recommend starting to use the glued object only after 24 hours.

Precautionary measures

At first glance, cold welding itself may seem like a harmless composition, but certain safety measures must be observed when working with it:

• It is preferable to work in protective glasses and gloves - do not allow the composition to come into contact with exposed skin or eyes. In the event of a traumatic situation, you need to rinse the damaged area of ​​the body with clean water and immediately consult a doctor;
• The adhesive mass should be stored out of the reach of children and pets;
• Cold welding particles should not be allowed to come into contact with food.

Typical errors during operation

These primarily include:

• Inattention to the expiration date - an expired expiration date will cause poor-quality sutures;
• Surface preparation contrary to the recommendations of the welding manufacturer - the welding seam may simply fall off;
• Unsealed storage of the adhesive composition - the composition will simply harden and will not be suitable for use (for plastic compositions it is possible to heat them in warm water, but this will reduce the quality of the seam);
• Use of the composition for other purposes – use of the composition for welding materials for which it is not intended;
• The use of the composition without taking into account the conditions of future operation - if we are talking about the operation of a repaired object under conditions of elevated temperature background, then the welding applied to it must be heat-resistant;
• Failure to comply with proportions when mixing liquid compositions - incorrect adherence to proportions can lead to an almost complete lack of adhesion (adhesion) for these compositions.
