First of all, the width of the handheld laser welder weld seam is related to the thickness of the material to be welded. For thinner materials, the width of the weld is generally narrower and can be controlled in a few millimeters. And for thicker materials, the width of the weld seam may be wider, can reach tens of millimeters.
Secondly, the width of the weld is also related to the welding requirements. In some applications that require high welding strength, the width of the weld seam may be wider to increase the strength of the weld. And in some applications that require a high degree of appearance, the width of the weld may be narrower to keep the welded area looking good.
In addition, the width of a handheld laser welder's weld seam is affected by the welding speed and power. Generally speaking, the width of the weld seam may be narrower when the welding speed is faster and the power is higher. And the slower welding speed and lower power, the width of the weld seam may be wider.
In short, the width of the weld seam of the handheld laser welder is determined according to the specific welding needs and the thickness of the material. In actual application, it needs to be adjusted and controlled according to the specific situation to achieve the ideal welding effect.
