  • Patent number: 12257655
    Abstract: A welding electrode apparatus may be mounted to a robot that presents it to a workpiece along a pre-programmed path conforming to the surface of the workpiece. The welding electrode apparatus has a first drive for rotating the welding electrode about its own axis. The electrode handle has a second rotating drive having an imbalance to impose vibration on the welding rod transverse to the axis of the rod. The first drive may turn relatively slowly; the second drive may turn more quickly. The first drive has an electrical pickup by which to carry DC power to the electrode. The two rotating drives impose two frequencies of vibration into the apparatus, causing a make-and-break contact for low power spark deposition, while at the same time causing the electrode to bounce and impact the surface. The forward end of the apparatus may include a cowling and a delivery line to provide shielding gas to the electrode.
