All materials that are going to be welded require proper preparation: plate cutting, edge finishing depending on the cutting method used, beveling in V, K, X or Y, and finally welding the parts to be joined.
Oxy-fuel cutting and edge preparation
Oxy-fuel cutting is a thermal cutting process that separates material through combustion. Compared to other cutting techniques, it offers clear advantages: it allows cutting thick materials quickly and with relatively low energy consumption.
For this reason, it remains a widely used solution in many manufacturing processes.
However, when the goal is to achieve precise weld preparation, oxy-fuel cutting often requires additional operations. The heat affects the material properties, cutting precision is lower, and the resulting edges contain burrs and irregularities that must be corrected through grinding, shot blasting, or manual finishing. In addition, the resulting chamfers are not always consistent in terms of angle, width, and finish.
The hidden cost of the process
The issue is not only the cutting itself, but all the additional time required afterwards: rework, adjustments, and corrections. All of this directly impacts productivity and profitability.
In many companies, weld preparation can represent up to 20% of total production time, when it could be significantly reduced.
How to reduce time and costs without losing efficiency
When reworking is carried out using grinders or manual chamfering tools, the process can take around 60 minutes for a 6-meter plate on one side, not including the physical effort required from the operator.
This is where a dedicated bevelling solution makes the difference.
CEVISA bevelling machines perform beveling through material removal using a toothed milling cutter, reaching speeds of up to 2.6 meters per minute. This allows oxy-fuel cutting processes to be complemented with a much faster, more precise, and cost-effective edge preparation.
Depending on the thickness and type of material, the most suitable machine model can be selected, with similar working speeds across the range.
