S1: SMAW One _ SMAW Fillet Welds on Mild Steel Flashcards
Joint Preparation
Objective 1: Preparation
Clean and fit materials properly, ensuring correct alignment and gap for welding.
Equipment Setup
Objective 1: Preparation
Select appropriate current, polarity, and electrode based on material and welding position.
Positioning
Objective 2: Welding Techniques
Maintain correct electrode angle, arc length, and travel speed to produce quality welds.
Fillet Welds
Objective 2: Welding Techniques
Techniques for various positions:
Horizontal Position: Maintain a slight drag angle.
Vertical Position: Use a slight upward angle, adjust travel speed.
Overhead Position: Keep a short arc, control bead size.
Inspection
Objective 3: Quality Control
Look for defects like porosity, undercut, and incomplete fusion. Ensure consistent bead appearance and penetration.
Repairs
Objective 3: Quality Control
Methods for correcting weld defects, such as grinding out and re-welding.
