Preventing Burn-Through in Thin Material Welding

Burn-through in thin materials occurs from excessive heat input exceeding the material's ability to conduct heat away from the weld zone. Prevention requires reduced heat input, proper gas selection, and modified welding techniques.

Prevention Techniques

  1. Reduce heat input. Lower voltage, increase travel speed, or use pulse welding modes.
  2. Use appropriate gas. Lower CO2 content reduces heat input for thin gauge applications.
  3. Employ proper technique. Skip welding, backstep technique, or copper backing to manage heat.
  4. Adjust joint design. Use lap joints or backing strips to support thin materials.

CORGON® 10

Low Heat Input

Why CORGON 10 works for thin materials: Lower CO2 content (10%) provides good arc characteristics with reduced heat input, ideal for materials under 3mm thickness.
