Aluminium’s high thermal conductivity can lead to distortion due to uneven heating.

Preventive Measures:

  • Preheating: Reduces thermal gradients, especially for thicker sections.
  • Clamping and Fixtures: Holds parts rigidly in place to minimize warping.
  • Controlled Welding Speed: Adjusting travel speed and heat input to avoid excessive temperatures.
  • Weld Sequencing: Alternating weld locations to balance stresses.
