Product Details:

The cutting, gouging and piercing by means of shielded metal arc welding principles is a flexible and economic method of removing metal. The process does not require any compressed air, gas or any type of special electrode holder as standard equipment can be used.

The coating on cutting and gouging electrodes develops a strong gas jet, which blows away the molten material. These electrodes are excellent for preparation prior to repair of cast iron. The jet drives out and burns away impurities and/or graphite on the surface and thus reduces the risk of cracking and porosity when welding later. Gouging of manganese steel can also be suitably done.

For gouging normally AC or DC- should be used, whereas for cutting and piercing DC+ is recommended. The arc is struck holding the electrode at 90° to the workpiece. Once the arc is ignited, the electrode has to be pointed in the appropriate direction at 5-1 0° to the job surface and pushed in the forward direction. A to-and fro motion has to be maintained to carrion with the cutting or gouging action. For piercing, the arc has to be struck in a vertical position and the electrode pushed down to penetrate through the material. The electrode is manipulated with a sawing motion to enlarge the bore.

Cobalarc - the future of hard facing. This range of tubular electrodes gives a host of advantages over conventional coated electrodes in respect of hard facing applications owing to its unique features.

Features:

• The prime weapons that provide the hardness in hard facing deposits are the metallic and non metallic carbides. In coated electrodes, the carbides are formed at the time of welding. Carbides, preformed, cannot be used in these electrodes because the high hardness renders them difficult to produce. But, Cobalt electrodes have the advantage that the preformed carbides are put inside a hollow mild steel tube
• In hard facing controlling the heat input is important because greater dilution will lower the hardness of the deposit. In this respect, Cornball gives a major headway because only a thin walled tube has to be melted instead of a solid wire. So the heat requirement will be considerably less and automatically the heat input will really be low
• The low heat input also reduces the heat-affected zone in the base metal
• Cobalt provides economy as the total loss involves only butt end loss and very negligible slag loss. Moreover, the butt end does not contain any carbide inside - it is only the hollow tube that is lost, so the actual loss is even lower
• The slag formation is very small in Cobalt. So the welder can apply the next run without wasting any time for desalinating. This gives an immense advantage of speed and productivity. So in 1 hour of arcing, Cobalt gives 2-2.5 times the weight of deposit than coated hard facing electrodes
• A near absence of slag does not mean that Cobalt deposits are exposed to the atmosphere for oxidation. The outer coating contains ingredients that burn in the welding arc and generate copious amount of fumes, which provides the shielding to the weld pool
• This outer coating has one more function. Since it contains non-hygroscopic stabilizers the mild steel tube is free from rusting giving these electrodes an indefinite shelf life. The rigid tube also protects the preformed carbides from degeneration over time

Product Details:

Brazing is a welding process, which produces coalescence of materials by heating them to a suitable temperature and by using a filler metal having melting point above 450°C. The filler metal is distributed between closely fitted surfaces of the joint by capillary action.

The placement of the filler metal affects the quality of the joint. For normal lap joints, the filler metal should be supplied from one end only and allowed to flow completely through the joint by capillary action.

The correct fluxing material must be used. The placement of the flux also affects the quality of the brazed joint. Paste flux is the most common from and is usually spread over the surfaces to be joined. It is also painted on the per-placed brazing filler materials.

For some of the brazing methods a special atmosphere is used instead of flux, which is selected based on the metals being joined. When atmospheres are used flux may not be required. The atmosphere is the product of the combustion of the flame. The neutral or reducing flame is usually used. A slightly oxidising flame may be used for certain other materials.

Nickel Alloys:

Nickel and nickel based alloys are used in industrial applications for:

• Corrosion resistance
• Heat resistance and high temperature properties

Cryogenic Properties:

• Preheating is not normally required unless there is a risk of porosity from moisture condensation. PWHT is not usually needed to restore corrosion resistance. Incontinence type of deposit is used for obtaining high temperature, high strength joints designed to perform at over 200°C such as on creep resistant chrome molybdenum steels to stainless steels. These types are suitable when welding sections over 25 mm. For welding tool steels requiring toughness under repeated cyclic stress and oxidation resistance upto 1000°C, Chastely C type of deposit is regularly used. The drop in strength and hardness as the temperature goes up is very gradual

Copper And Copper Alloys:

• The main features of copper and its alloys
• Corrosion resistance
• Electrical and thermal conductivity

In terms of weld ability, the alloys have quite different welding characteristics. Copper needs substantial preheat to counteract the high thermal conductivity. But alloys like cu pro-nickel can be fusion welded without any preheat, as the thermal conductivity is similar to low carbon steel.

Buttering technique should be used to join copper alloys to carbon / stainless steel. This is to take care of the copper migration to the HAZ and precipitation at the grain dares. The buttering, with a pure nickel electrode, can be applied on either the copper or the steel side. The groove has to be filled up a stainless or a bronze type of deposit.

The preheating should be 300-500°C when buttering copper or bronze whereas the preheating temperature has to be chosen according to the base material if the buttering is done on the steel side.

Aluminum And Aluminum Alloys:

The characteristics of aluminum and its alloys that make them amenable to fabrication are enlisted below.These are:

• Light weight
• Good corrosion resistance

The filler metals used for welding aluminum alloys are selected considering the following aspects:

• Weld ability of the parent metal
• Minimum mechanical properties of the weld metal
• Corrosion resistance

Nominally matching filler metals are often employed for non-heat-treatable alloys. However, for unalloyed or low alloyed materials and heat-treatable alloys, non-matching fillers are used to prevent solidification cracking.

Cobalt Alloys:

• Cobalt alloys are known for excellent wear resistance at high temperatures and the weld metal is used in cutting and shearing operations at temperatures exceeding 600°C. These deposits exhibit high shock resistance, high hardness at elevated temperatures and scaling resistance and can be used in stamping dies, trimming cutters, trimming punches, etc.

Product Details:

The powder welding process basically uses a simple ox-acetylene torch where finely divided powder is fed into the flame from a hopper attached to the torch. The powder melts to give a dense coating and forms a strong bond with the base material by surface alloying and diffusion. Fluxing elements such as boron and silicon are necessary in the powders for good metallurgical bond. This process is typically used for deposits having thickness between 0.2-12 mm, in particular for smaller parts or repairs. The process is applicable only in iron base, nickel-base or copper-base material.

Hot metal powder alloys are mostly nickel-based. Nickel when added with boron gives hardness due to formation of brides. The percentage of boron can be monitored to achieve a particular hardness range. Boron also brings down the melting point of nickel and helps the powder to fuse much below melting point of steel. For enhanced protection against wear and increased corrosion resistance, silicon along with other special alloys is added. Some cobalt-based powders are also available but are not as cost effective as nickel-based powders. Tungsten carbide is added to a nickel bride matrix to combat high pressure abrasion.

The flow of powder and spreading on base metal depends primarily on two characteristics : Powder particle shape and size. The mesh size determines the acceptability of the powder to be used by hot metal spray process. Usual range is between 15-160 microns. The shape of powder is very important for the welder as it solely determines the ease of flow of the powder through the nozzle of hot spray gun. The powder shape is dependent on the method of manufacture of the powders. Gas atomized powder have spherical particles resulting in a smooth flow through the nozzle and higher deposition rate. Ground powders have irregular shape and the flow characteristics are poor.

Advantages of Powder Spray:

• Thin layer can be given with hardness up-to 65 HRC (upto 0.15 mm thickness)
• Coating is uniform; hardly any post-machining required
• No heat treatment is required
• Self-fluxing: no slag cleaning required
• For machine parts, life obtained is much higher

The limitations are:

• Not economic for thicker build-up on big jobs
• Not applicable for aluminum, magnesium components
• For big jobs furnace preheating and melting is required
