Laser Cladding-Keepsake Engineering Consultancy Pvt Ltd

Cladding is a welding procedure that puts weld metal on the surface of the work, as opposed to joining two pieces of material. Generally, this is used for corrosion resistance or wear resistance and frequently a different material is used for the clad than for the base metal.  In hot wire welding, the power supply controls the heat of the filler wire prior to its introduction into the weld puddle. Arc energy that would usually go into melting the wire provides more penetration, while heating of the wire almost to the melting point by a separate power supply increases deposition beyond that possible with standard cold wire TIG. In cladding applications where the part is rotated, the hot wire solution can result in weld deposition that approaches MIG speed, but with TIG quality.

Laser cladding is realized either as wire (laser hot wire cladding) or powder cladding. The laser beam creates a molten pool at the workpiece surface, to which is simultaneously added the laser coating material (wire or powder) molten by the laser. The exposure time is short, which creates only a short delay as the cooling is quick. The result is a layer that is connected with the basic material metallurgically. It is tougher than those coatings created by thermal spraying, and compared to hard chromium plating, for example, it is harmless to health, too.

Advantages:

1. low exposure time and depth of the laser
2. metallurgical connection of layer and basic material
3. layers are more resistant than thermal spray coatings
4. high surface quality and low warpage, with almost no post-processing necessary
5. short laser cladding process period, high-energy efficiency

KECPL is an Ahmedabad based professionally run decade and half old co. specialized in the field of thermal spray coatings & carbide wear parts. Team is headed by a technocrat who has decades of stint with engineering icons L & T. To produce quality coatings we have an excellent thermal spraying facility and highly skilled and trained team of engineers to do the job successfully. During the period of time co. has renewed their facilities according to the technical advancement adopted in the industry. We are presently equipped with Six axis articulated arm robot to operate our Plasma transferred arc pulsed 350 amp power source, High velocity oxy-fuel systems, Arc spray systems and flame spray guns. We also have manipulators for down hand welding capability.

KeepSake Engineering Consultancy is a manufacturer, job shop and a specialised engineering firm. The one thing that its products and services have in common is that they reduce wear caused by abrasion, friction, heat and corrosion. The company specialises in applying Thermal Spray Coatings to solve problems related to wear. It has five categories of thermal spray systems, viz., Flame spray (Rod rokide, powder), HVOF (tungsten carbide), Arc Spray, Plasma Transferred Arc, Spray and Fuse. It applies ceramic, carbide, cobalt and Nickel alloy coatings.

We aim to employ this unique technology for life enhancement of wear prone parts belonging to various industries. To achieve that goal we have developed special kind of jigs and fixtures to maintain uniformity and accuracy of dimensions of coated parts. This efforts and care resulted in to a sound clientele of OEMs and big end users who are highly satisfied with the performance improvement they are getting by such coatings and wear parts.

We are well aware that we are in the maintenance field where emergency is very routine phenomena. That’s why at the customer level we have customer support engineers, who continuously work with customers to solve their wear and corrosion related problems.
