Cutting Techniques for Welding Glass

Here are some effective cutting techniques for welding glass:

1. Scoring the Glass: Hold the glass cutter firmly, align it with the marked cutting line, and apply consistent pressure while making a single continuous score along the line. It is crucial to maintain a steady hand and avoid stopping or lifting the cutter during the process. Make sure to score the glass only once, as multiple scores may lead to an uneven break.

2. Breaking the Glass: With the scored line facing up, carefully position the glass breaker at one end of the scored line. Apply gentle pressure while moving the breaker along the line. The glass should break smoothly along the scored line. If necessary, reapply pressure at specific points to ensure a clean break.

3. Fine-Tuning the Cut: After breaking the glass, inspect the cut edges for any roughness or unevenness. Use a glass grinder if necessary to smooth out any imperfections. Be cautious while using the grinder, as excessive grinding can weaken the glass or alter its shape.

Safety Measures to Follow While Cutting Welding Glass
