For information on welders and peripheral devices, please contact the manufacturer to receive a more accurate answer. ↓↓↓↓↓↓↓ korea@nswel.com Hello everyone. There is a prejudice that laser welders are only used for welding thin sheets. So, is laser welding for pressure testing impossible? Today, I made a pressure vessel using only precision welding. If a pressure vessel welded with only precision welding with a width of 2 to 3 mm passes the pressure test, it will likely be applicable to many places. Also, at the end of the video, we added information about what results are obtained when electropolishing the laser welded part. We will try other interesting tests in the future. Thank you for watching and have a great week. #laser #welding #pipe #enter #test #electropolishing #factory #machine #steel #crafts #Tips #secret #trick #amazing #DIY #idea #future #technology #technique #pipe #HAGOJIBI #video #weldingmachine #Laserwelder #laserweldingmachine
