Disclosed example robotic welding systems include: a robotic manipulator configured to manipulate a welding torch; and a robot control system, comprising: a processor; and a machine readable storage medium comprising machine readable instructions which, when executed by the processor, cause the processor to, during a robotic welding procedure involving the robotic manipulator: prior to initiating an arc as part of the robotic welding procedure, identify an arc warning event; in response to the arc warning event, output at least one of a visual notification or an audible notification proximate to the robotic manipulator; and control the robotic manipulator to perform the robotic welding procedure involving initiating the arc using the welding torch.

A device and a method for removing worn or damaged wear-resistant steel plates installed over the surface of substrates subject to wear by contact with abrasive materials, wherein said wear-resistant steel plates are bonded to said substrate by a heat-sensitive adhesive. The device has a frame, one or more electrical resistors to raise the temperature of said wear-resistant steel plates when said frame is positioned above said wear-resistant steel plates, one or more electromagnets being configured and adapted to contact and hold said wear-resistant steel plates when said electromagnets are activated by an electrical current, and one or more handles to separate the device magnetically holding said wear-resistant steel plates away from said substrate. The device may also comprise a thermocouple and a PID controller to control the temperature of the wear-resistant steel plates in a range between 350 C. and 450 C. Optionally, an audible alarm is provided to indicate the operator that the desired temperature has been reached and that separation of the device holding the wear-resistant steel plates away from said substrate can be done. Optionally, the device is split into two separate and independent sections, a first heating section comprising the heating elements to raise the temperature of the wear-resistant steel plates and a second removing section comprising the electromagnets used for engaging and separating the wear-resistant steel plates. Using two separate sections for heating and removing the wear-resistant steel plates provides flexibility regarding the size of the device and allows for removal of wear-resistant steel plates while other wear plates are being heated.
