Electrical conductivity matters in welding because a poorly conducting joint can create resistance, generate heat, and cause a connection to fail under load. Silver is one material with a notably high electrical conductivity rating. Here’s how that property affects... by Tami Holly | Sep 18, 2026 | Pot Metal, Super Alloy 1
Pot metal is a general term for low-cost casting alloys that contain metals such as zinc. Because these alloys have a low melting point, too much heat can destroy the part before the repair is complete. The damaged area can soften or collapse while you’re still... by Tami Holly | Sep 9, 2026 | 72 Electrode, 77 Electrode, Cast Iron
Cast iron can be a difficult material to weld due to its high carbon content and sensitivity to sudden temperature changes. If you need to repair a cracked block and want to avoid the post weld cracks that are common with cast iron, you need to control heat throughout...
