After the weld has cooled completely, carefully test the alignment and function of the barrel. This may involve test-firing (under the supervision of a qualified firearms professional) to ensure proper operation and accuracy.
5. Safety Checks & Final Touches
Before declaring the barrel installation complete, one final safety check is paramount.
5.1 Stress Testing the Barrel
If possible, subject the barrel to a stress test. This might include pressure testing or a controlled firing test to verify the strength and reliability of the weld. This should only be undertaken by a qualified gunsmith or in a controlled environment.
5.2 Cleaning and Lubrication
After the tests, carefully clean the barrel and receiver to remove any welding debris or spatter. Lubricate all moving parts to ensure smooth operation.
6. Troubleshooting Common Issues in Barrel Pinning and Welding
Even with careful execution, issues can arise.
6.1 Addressing Weld Defects
If you encounter weld defects such as porosity or incomplete penetration, grind the defective weld down and re-weld the area. Ensure proper cleaning and preparation before re-welding.
6.2 Misalignment Issues
If misalignment occurs, carefully remove the pins, correct the alignment, and repeat the welding process. It’s vital to get the alignment right before welding.
