Welding

Crestt has been focusing on finding Innovative Technical Products in the premium product sphere of the Industrial Fabrication with key strength in SS, Al, Titanium and other exotic materials.

If you are in the fabrication business with a metal which is upwards of Rs 200/kg e.g. SS, we are the people you should meet. At least that’s what most of our clients say (wink).

Some of our feats include

  • Successfully managing over 1000+ Welding Machines at one of the World’s largest Engineering Companies with negligible breakdown ratio.

  • Working together with multiple SMEs helping them to move from MMAW/SMAW(Stick Welding) to GMAW(CO2/MIG Welding).

  • Working with sheet metal customer to eliminate welding and move to cold bonding e.g. Tapes, Adhesives.

  • 250mm deep single stroke drilling.

  • Replacing hazardous K2 paste with welding cleaning.

  • Training workers to move from Thoriated to radiation free E3/Lanthanted Tungsten Electrodes.

  • Educating and moving customers to wet tungsten grinding.

  • One of our key focus for 2019-20 is Automation using SPMs, Industrial & Collaborative Robots in Key Sectors like Exotic Metal Fabrication, Premium Industrial Manufacturing, etc. Hence, if you are an MNC or a Indian Company wanting to dominate the Quality Sphere, Crestt is the company to connect with.

Electrode Welding

Manual Arc Welding

SIMPLE, VERSATILE, EFFECTIVE

Shielded metal arc welding (SMAW) is usually the first welding process that welders are taught during training. It is easy to learn, but already offers insights into the way that welding systems work and into the ratio of metals to electrical voltage.

  • The process is mainly used in steel and pipeline construction, but is also used in metal trade and industry.

  • Manual metal arc welding allows for any type of weld seam and position, irrespective of whether this involves restricted or overhead positions, vertical up seams or vertical end welding.

MIG/MAG welding

Gas Metal Arc Welding

THE HIGH-SPEED WELDING PROCESS

A differentiation is made between metal inert gas welding (MIG) and metal active gas welding (MAG).

  • MAG welding uses active gases such as pure CO2 or mixed gases (argon, CO2, O2) in various compositions. These are highly reactive. The MAG process is used for unalloyed, low-alloy and high-alloy materials.

  • MIG welding, on the other hand, uses inert, i.e. unreactive, gases such as pure argon and helium or mixtures of argon and helium. The process is suitable for welding materials such as aluminum, copper, magnesium and titanium.

  • LOW SPATTER CONTROL - LSC - High-quality weld seams with the lowest level of spattering and increased deposition rate.

  • COLD METAL TRANSFER - CMT - The extremely stable arc allows for the best results with all materials.

  • PULSE MULTI CONTROL - PMC - Modified arc for even better results in MIG/MAG pulsed-arc welding.

  • Most frequently used in the gas metal arc welding is steel. In addition, aluminum and stainless steel alloys can also be welded well with MIG/MAG

Tungsten Inert Gas welding

Gas Shielded Fusion Welding

CLEAN SEAMS, STABLE CONNECTIONS

  • Wherever optimum quality and spatter-free weld seams are required.

  • TIG welding is suitable, among other things, for stainless steels, aluminum and nickel alloys as well for thin sheet metal made of aluminum and stainless steel.

  • Materials used in TIG welding include stainless steels, aluminum and nickel alloys and thin sheets of aluminum and stainless steel.

  • It is used in pipeline and container construction, in portal construction and in aerospace applications.

  • The tungsten electrode is the heart of TIG welding.

  • A cold-wire feed increases productivity: The welding speed increases and the filler metal is fed precisely and evenly to the weld pool.

  • TIG hot-wire welding, the filler metal is heated. The deposition amount and rate increase, the welding speed rises and the fusion is reduced.

  • Arc Tig welding process is used for mechanized joint welding. It allows for an excellent weld seam appearance, reliable full penetration welding of the root pass and very high weld quality. Due to the increased welding speed and reduced work to prepare the seam, ArcTig also makes the whole welding process more cost-effective.

  • Cladding is a process in which the components are coated with special alloys in order to extend their service life significantly. This coating is carried out through mechanized electro-surfacing. Fronius Speed Cladding makes the coating process up to three times faster and more efficient.

  • Orbital Welding is used for pipeline construction, food industry & chemical industry. With the moveable orbital technique, it is not only possible to produce pipe-to-pipe connections, but also to weld pipes into pipe baseplates.

Multiprocess welding systems

Systems that can carry out more than one welding process to a high standard.


FRONIUS WELDING PROCESSES


Cold Metal Transfer - CMT

Pulse Multi Control - PMC

Low Spatter Control - LSC

Robotic Welding

Manual interventions usually lead to interruptions in the production process and so have a negative impact on productivity.

Plasma Welding

When high quality is required, especially with sheets and other components up to 8 mm thick, plasma welding offers numerous advantages, including high welding speeds, deeper penetration and no more need for weld seam preparation.
