Abstract

PURPOSE:To improve welding efficiency by installing a downhand welding torch above the fin and an overhead welding torch below the fin and in front of the downhand welding torch, and welding both sides of the fin and tube simultaneously moving the fin and torch. CONSTITUTION:In welding a fin 11 and a tube 12, a downhand welding torch 10 is installed above the fin 11 and an overhead welding torch 13 is installed below the fin 11 and in front of the downhand welding torch 10. Then, both sides of the fin and tube are welded simultaneously moving the fin 11 and torches 10, 13.
