Process:

The well-known SAW method has been widely used with strip electrodes since the mid-1950s. A strip electrode, normally measuring 50 x 0.5 mm or 90 x 0.5 mm is used as the (usually positive) electrode and .an electric arc is formed between the strip and the work-piece. Flux is used to form a molten slag to protect the weld pool from the atmosphere and helps to form a smooth weld bead surface.

Highly alloyed materials, such as stain-less steel or nickel-base alloys, are needed in many applications to provide protection against corrosion. However, the comparatively high cost of these materials in many cases makes deposition of a protective layer on a less expensive load bearing mild or low alloy steel economically the most realistic alternative.

Furthermore, weld surfacing with A6S SAW Strip Cladding head gives the designer and the fabricator a great degree of freedom providing the possibility to choose a wide variety of parent materials and consumables. Cladding by weld surfacing also allows for flexibility in production of objects having various shapes and sizes. Stainless steel cladding is widely used in production of components where corrosion resistance is required together with strength above that of standard stainless grades.

Features:

• Economical - Provides an economical solution for surfacing with high alloyed materials such as stainless steel or nickel-based alloys.
• Dynamic - Choose a wider variety of parent materials and consumables.
• Used in combination with standard welding head.
• Additional Strength and Corrosion Resistant - Stainless steel cladding is widely used in production of components where additional strength or corrosion resistance is required.
• Variable Strip - Welding head can be fitted with electrode strips as wide as 30-100 mm (1.2-4.0 in.) and as thick as 0.5 mm (0.02 in.).

Scope of supply includes:

1. Power source
2. Welding Positioners / Turntables / Rotators
3. Column and Boom
4. SAW Cladding Heads
5. Water Chillers
6. Control Automation for automatic welding

Process:

Electro-Slag Strip Cladding (ESSC)/Electro-Slag Welding(ESW) is a development of submerged arc strip cladding which has quickly established itself as a reliable high deposition rate process. ESW strip cladding relates to the resistance welding processes and is based on the ohmic resistance heating of a molten electrically conductive slag.

There is no arc between the strip electrode and the parent material. The heat generated by the molten slag melts the surface of the base material, and the edge of the strip electrode is submerged in the slag and flux.

The penetration achieved with ESW is less than that with for SAW because the molten slag pool is used to melt the strip and some of the parent material. The temperature of .the slag pool is about 2300C, making it to water-cool the contact jaws.

ESW uses higher welding currents than SAW strip cladding so the welding heads used are more heavy duty. The following shows the features of ESW compared with the strip cladding process.

Features:

• Increased Welding Speed- Increased welding speed (50%200%), results in higher area coverage in m²/h.
• Flux Consumption Low.
• Low Solidification Rate- Aids de-gassing and increases resistance to porosity. Oxides can rise easier out of the molten pool to the surface; resulting in a metallurgically leaner weld metal which is less sensitive to hot cracking and corrosion.
• Higher amperage and current density.
• Needs only one layer - Due to the properties of ESW often only one layer is needed to fulfill the cladding requirements.
• Reduced Consumable - Further the consumption of consumables is significantly reduced.
• Useful For Productive cladding of second layer, when two layer technology is required.

Process:

Hardbanding is the process of depositing hardfacing alloys onto drill pipe tool joints, collars, heavy weight drill pipe and other down hole components to protect both casing and drill string assets from abrasive wear. Hardbanding is most commonly applied to the box end of drill pipe tool joints using a MIG welding process, bonding the hardbanding alloy with the parent steel of the drill pipe. There are, however, other hardbanding application methods that are occasionally used including laser and plasma arc processes.

Arcraft has invested heavily in R&D resources and aligned with technology partners who are able to provide superior alloy design methodology to quickly address the changing needs of the industry.
