He now has a law degree and keeps threatening to go into private practice with a shingle that reads, Tim N . Sims : Attorney-At-Law and Spot Welding.
Historically, soldering coppers were standard tools used in auto bodywork, although body solder has been mostly superseded by spot welding for mechanical connection, and non-metallic fillers for contouring.
Friction stir spot welding is successfully used for the bonnet ( hood ) and rear doors of the Mazda RX-8 and the boot lid of the Toyota Prius.
Alternatively, under local anaesthetic, the corneal layer may be gently removed with a fine needle, cauterised ( heat or laser ) or'spot welding'attempted ( again with lasers ).
Spot welding is a resistance welding method used to join two or more overlapping metal sheets, studs, projections, electrical wiring hangers, some heat exchanger fins, and some tubing.

There, the method is often used for arc spot welding, thereby replacing riveting or flux cored arc welding is better suited for outdoor use such as in construction.
The advantages of the method include efficient energy use, limited workpiece shear is needed, spot welding is used in preference to more costly mechanical fastening, such as riveting.
The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time ( approximately 10 100 milliseconds ).
Many welding processes require the use of a particular joint design; for example, resistance spot welding, laser beam welding, and electron beam welding are most frequently performed on lap joints.
Yaskawa Motoman produces robotic automation for industry and robotic applications, including arc welding, assembly, clean room, coating, dispensing, material cutting ( laser, plasma, waterjet ), materials handling, materials removal, and spot welding.
