Welding Using Battery. Once we are done with Circuit and assembly of Transformer we can mount the Transformer on a piece of wood and hold it down using some screws. Cell casing and terminal dimensions may constrain possible contact geometries.
Each of these welding techniques has its own characteristics depending on the material properties and contact geometry. YouTube user engineer775 shows in the video above how to setup an emergency welding rig by connecting two 12v car batteries in series wiring them into a single 24v battery. Try sparking up deliberately and keep doing it.
In one of my trips to China in the late 1980s I visited a laser welding system builder in Wuhan that was supplying solid-state laser systems to join battery pairs a booming job-shop industry then.
What are you welding today. Resistance and laser welding micro TIG welding laser marking laser surface cleaning and. As compared to welding cables the copper strands of battery cable are thicker and are insulated using XLPE or PVC for resistivity feature. Each of these welding techniques has its own characteristics depending on the material properties and contact geometry.
