Abrasive Belt Grinding For Weld Preparation
The abrasive belt rapid grinding system from Surtech is designed for welding preparation applications, particularly when working with highly stressed load-bearing parts. Using the system, bevels are produced on straight edges of plates economically and with precision, according to the company. The repeatable, highly accurate welding edges are said to make it possible to achieve a high degree of efficiency in the subsequent welding processes and production of assemblies.
In automated welding, the best system is no help if the edge preparation is not up to the standard it should be. The oxyacetylene practice generally in use today is often no longer appropriate for the higher quality and economic efficiency requirements. The grinding belt system offers metal removal rates of 50-100cm3/min, a maximum thickness capacity of 50mm and bevel angles from 0-60-deg. It operates with belts in grit sizes from 24 to 36. Swarf is collected in a container and disposed of with other scrap metal.
Surtech said there is never any doubt about the quality of the bevels on high-strength fine-grained structural steels where the highly stressed areas of the welds are subject to routine testing and the conformation of the weld has a decisive influence on the quality of the welds. With the abrasive belt rapid grinding system, this quality is achieved. The side walls of the welds have a bright metal finish and the bevel angles and residual webs required can be repeated with great precision.
Abrasive belt grinding is said to be a simple operation that is quickly absorbed by the work force, particularly since it also improves working conditions and does not require extra remedial work before and after. Surtech said considerable time and space savings can be expected. The accuracy in manufacturing individual components ensures improved efficiency when producing the assemblies. Abrasive belt rapid grinding systems are suitable for continuous multiple-shift operation, and their compact and rugged construction is ideal to withstand these tough conditions.
