HAZ in Aluminum Welds

Understanding Heat Affected Zone HAZ

Understanding HAZ in Aluminum Welds The Heat-Affected Zone (HAZ) is the unseen neighborhood around a weld where temperatures from the welding process change the metal’s microstructure without melting it. In aluminum welding the HAZ frequently controls whether a joint will meet strength, toughness, or corrosion requirements — more than the …
