Percussion welding directly bonds two metals using a high-voltage electrical arc and forge pressure before the molten metals solidify, creating a strong, direct bond between the contact and substrate.
Provides a bond integrity of 95-100% across the bond area.
Operates without solder, generating less heat and maintaining the substrate and contact hardness.
The heat-affected zone is minimal, just .002” into the contact tip and substrate, allowing for smaller, more efficient contact tips.
Generally more expensive than brazing, with about 10% of the contact material lost during the arcing process.
Requires additional labor to size the contact tip surface.
Furnace brazed contacts are 15-20% less costly and the substrate is fully annealed.
TRIAC’s percussion welding, performed underwater using high-amperage electrical arcs, results in virtually indestructible joints with a liquid metal weld area of approximately .005” deep. This process avoids the impurities and voids found in brazed contacts, enhancing current-carrying capacity and longevity. TRIAC offers 100KVA and 250KVA percussion welding capabilities for superior performance across various applications.
