Can grinding and welding processes be significantly improved by selecting an optimized combination of abrasive and safety solutions? Let's take a look...
We'll be looking at production time, hand-arm vibration exposure, noise dose.
We'll be comparing conventional solution, depressed center grinding wheel, separate face-eye-hearing-respiratory protection, to performance solution, 3M Cubitron fibre disc, 3M Speedglas integrated welding and respiratory protection with separate eye and hearing protection. Let's get going with the challenge.
A technician dons 3M Speedglas G5-01 welding helmet with 3M Adflo powered air purifying respirator. Wearing separate eye and hearing protection. He installs a 3M Cubitron Fibre disc 36 plus on a 3M electric angle grinder.
A side by side compares weld preparation, conventional solution with performance solution, including noise and vibration monitoring meters.
The technician grinds metal in both scenarios. At 20 seconds, conventional vibration exposure is 0.302 points, vibration magnitude is 4.7 meters per second squared, noise dose is 94. Performance solution, vibration exposure is 0.094 points, vibration magnitude 5.1 meters per second squared, noise dose 98. On the performance side he changes plates and continues. At 39 seconds, the conventional solution changes plates.
At 39 seconds, the performance side begins welding.
The side-by-side videos speed up 1.5 times.
The conventional side continues grinding. At 1 minute 23 seconds, vibration exposure is 1.163 points, vibration magnitude is 0.3 meters per second, noise dose is 530. The welding begins on conventional solution.
Both video streams return to normal speed.
On the conventional solution, the welder switches head and face protection.
The conventional solution video is sped up 1.5 times.
The welding continues on the conventional solution side. At 2 minutes 6 seconds it ends on the performance side.
The technician on the performance solution lifts his visor.
Weld removal begins on the performance side.
At 3:18 on the conventional side, weld removal begins. The welder has to switch eye and face protection again. On the performance side, at 2 minutes 30 seconds, vibration exposure is 0.312 points, vibration magnitude is 3.6 meters per second squared, and noise dose is 208. The conventional side speeds up to triple speed. The performance side is completed at 2 minutes 49 seconds with 0.400 points of vibration exposure and noise dose of 214.
The conventional side completes at 4 minutes 39 seconds with vibration exposure of 2.086 points and noise dose of 671.
Let's take a look at the data and make some comparisons.
Time comparison, 40% faster. (1) 4 minutes and 39 seconds versus 2 minutes and 49 seconds. Vibration comparison. 81% reduction in vibration. (2) 2.1 vibration exposure points versus 0.4. Noise comparison. 68% reduction in noise. (2) 671 noise dose versus 214. The winner, performance solution.
3M Precision-Shaped Grain featured in our fibre grinding discs can help to increase cut rate, reduce vibration exposure, reduce noise energy.
3M Cubitron 3 fibre grinding discs are ideal for a variety of applications. Available in the following grades: 36 plus, 60 plus, 80 plus. The remarkable power of 3M Cubitron 3 also extends into other product forms — cut off wheel, depressed center grinding wheel, quick release Roloc discs and cloth belts.
3М Welding Solutions are better adapted to the welder's needs thanks to integrated PPE, respiratory eye and face, high level of respiratory protection according to EN 12941 and OSHA, no fit-testing requirements, natural color and contrast thanks to the 3M Speedglas Natural Color technology.
We understand that no two fabrication professionals are the same. 3М provide options to allow workers undertaking welding and grinding tasks to select the protection they want to wear. The versatile welder: 3M Speedglas G5-03 Pro and Pro Air. Touch to change from weld mode to grind mode. Lightweight design for ultimate versatility and comfort. The heavy-duty welder: 3M Speedgas G5-01, flip up welding visor, wide field of view when grinding.
Speak to your 3M representative and find out how combining the latest 3M Cubitron 3 abrasives and 3M Speedglas products can transform your grinding and welding process. This video made in collaboration with GT Trailers.
This video captures hand-arm vibration and noise levels, and completion times during a single challenge. Other welding and grinding activities may produce different experiences – results may vary. Always follow local regulation and guidance when selecting PPE and follow the specific user instructions of your PPE.
When it comes to fabricating, assembling or processing anything around the world, 3M knows efficiency is key. From ultra-strong abrasives that keep processes running smoothly, to futuristic materials that literally lighten your workload. 3M innovative solutions keep your business and your employees working smoothly with innovative industry leading solutions in abrasives, PPE and facilities safety solutions and adhesives and tapes.
