'Formula 62' Vibratory Stress Relief Equipment
Formula 62 – Model C and CSP units are designed to provide years of continuous service even under the adverse conditions found in the factory or the field. Each unit contains all the items necessary for operating, controlling, and recording the stress relief of weldments and machined components. The uni-body construction of the cabinet is functional as well as durable. Ample storage space is provided to house the heavy-duty vibrator and accessories. The interior electronics section is sealed off from outside sources of contamination such as oil mist vapour, dirt or abrasive grit. The machine is portable and can be used on any 220/230 V, 50 Hz., single-phase power source at 100% duty cycle. VSR equipment is used in diverse industrial segments like heavy fabrications, welded structures, castings, stainless steel, aluminium, heavy machined components, weld repaired jobs, etc., for specific applications. The company can also offer solutions as per the specifications provided by the clients, so that their exact demands can be catered.

Vibratory Stress Relieving Services (VSR)
Based on the weight of the piece, the VSR method introduces into it high amplitude and low frequency vibrations for a given period of time. This relieves residual stress without distortion or alteration of tensile strength, yield point or resistance to fatigue, and the static equilibrium is restored. The most efficient vibrations are the resonant ones, because in the resonance frequency vibrations stress is better distributed, compared with sub-resonant frequency. Low frequency vibrations carry high amplitude energy and are very efficient in the significant decrease of peak residual stress in metallic parts and welds. The equipment usually employed consists of a sturdy vibrator of variable speed, which is attached to the piece and an electronic control panel. Both are mounted into a portable cabinet. Also attached to the piece is an accelerometer that detects vibrations and transmits a signal to the control panel. The resonance point is then determined and displayed on a dial. If the vibrator is equipped with a recorder, a chart can also be obtained.
