Abstract:
To highlight the importance of resistance spot weld in the automotive industry, it's important know that a vehicle has on average 4,000 welding spots [BROWN; SCHWABER 2000] and based on worldwide vehicle production in 2015 with 90.78 million vehicles produced [OICA, 2015], were performed more than 363 billion welding spots. The number of machines in manual and automatic workstations (robots), based on 20 points by equipment and production of 45 vehicles / hour add up more than 20 million of welding machines in all over world. According new production lines are being introduced using the adaptive dynamic resistance control the welding constant current control are being replaced, so understand this technology and know implement it with efficiency needs a deep knowledge in how dynamic resistance works and correlate his behavior with the problems that causes failures in welding, so is necessary give for the welding engineers this knowledge.
