Abstract
A handheld laser trimming and welding device can include a handheld laser trimming and welding wand and a nozzle. The nozzle can extend from the handheld laser trimming and welding wand to a distal portion, and the nozzle can have an aperture on the distal portion. The distal portion of the nozzle can be configured to optically communicate a laser to the distal portion of the nozzle and fluidically communicate a pressurized gas to the distal portion of the nozzle.
Claims15
A handheld laser trimming and welding device comprising:
- a laser welding wand;
- a nozzle extending from the laser welding wand to a distal portion, the nozzle having an aperture on the distal portion, the nozzle configured to optically communicate a laser to the distal portion of the nozzle and fluidically communicate a pressurized gas to the distal portion of the nozzle;
- and
- a pressure wheel assembly attached to the laser welding wand, the pressure wheel assembly configured to apply pressure to a working sheet while the handheld laser trimming and welding device welds the working sheet, the pressure wheel assembly including:
- an attachment mechanism configured to attach the pressure wheel assembly to the laser welding wand;
- a main support beam extending from the attachment mechanism;
- a first pressure wheel support arm, extending from the main support beam;
- a second pressure wheel support arm extending from the main support beam such that the main support beam, the first pressure wheel support arm, and the second pressure wheel support arm are U-shaped so that the first pressure wheel support arm positions a first pressure wheel to contact a first sheet of material and the second pressure wheel support arm positions a second pressure wheel to contact a second sheet of material;
- and
- a tension mechanism connected to the first pressure wheel support arm and the second pressure wheel support arm, the tension mechanism configured to apply tension to the first pressure wheel support arm and the second pressure wheel support arm to hold the first sheet of material and the second sheet of material between the first pressure wheel and the second pressure wheel.
