This won’t eventually lead to the glass cracking as temperature changes cause the metal to expand and contract?

- senorprogrammer 8y agoNo, the terms picosecond and micron are pretty integral to the process. Imagine using a propane torch to heat up the side of a single brick in an apartment building wall for a few seconds. The temperature change in that brick, considerable compared to all the others, will have effectively no impact on the building itself.
- yetihehe 8y agoYeah, but it's about long term stresses leading to cracking. I wonder how big elements you can weld with this. Centimeter scale windows for chips will probably have no problems. While screens in mobile phones - I suppose they will crack within weeks/months.
- AstralStorm 8y agoIt is very much possible that such essentially atomic level weld will be more resilient than the glass itself. The interesting bit is if anyone can make new and exciting multilayer material composites using this kind of welding.
- jcims 8y agoDefinitely possible, but I think that's something you could engineer your way out of by being very selective with materials, building in strain relief. Then of course test test test.
- d-sc 8y agoAs long as the thermal strain(deformation) and therefore stress is managed, it would be fine. There are design tables and values that one can refer to that limit maximum cyclic stress which might be particularly applicable here.
