5. Test Weld When Possible
To help ensure that all preparations are correct, you should perform a test weld on similar materials when possible. The more critical the piece, and the more expensive the material, such as titanium, the more important it is to conduct a test weld. Taking the time for this step in the process can minimize problems later, which is especially important on one-of-a-kind pieces or critical welds. Using similar materials for a test weld also helps with accuracy and gives you a feel for how the material will respond to the welding parameters.
Similar to clamping, test welding is an additional step in preparation that pays off in benefits later in the welding process.
