LPG Cylinder Longitudinal Welding Machine Multi-layer and multi-pass welding
LPG Cylinder Longitudinal Welding Machine has the ability to achieve multi -layer and multi-pass welding . From the perspective of welding technology, many LPG cylinder longitudinal seam welding machines use MAG (metal active gas shielded welding) welding technology. Taking the common thick-walled cylinder welding as an example, by reasonably adjusting key parameters such as welding current, voltage and welding speed, the welding operation can be completed in multiple times to achieve the goal of multi-layer and multi-pass welding. For example, when welding a cylinder with a wall thickness of 4-6mm , first use a larger current to perform a base weld to ensure good fusion at the root of the weld, and then adjust the parameters of each subsequent layer appropriately to ensure the quality of each layer of weld .

In terms of equipment structure, many welding machines are equipped with weld centering devices and welding gun fine-tuning mechanisms. The weld centering device can ensure that the weld of the cylinder is always directly below the welding gun during the welding process, so that the welding position is accurate and correct; and the welding gun fine-tuning mechanism can flexibly adjust the angle and height of the welding gun, so that the welding gun can accurately align each layer and each weld during multi-layer and multi-pass welding to ensure welding quality. In addition, some advanced LPG cylinder longitudinal seam welding machines are equipped with digital control systems, which can accurately control the wire feeding speed and accurately plan the movement trajectory of the welding gun, and complete multi-layer and multi-pass welding tasks in an orderly manner according to the preset program, which not only improves welding efficiency, but also ensures the stability of welding quality.
