Answer

Incorrect Arc Length

  1. What causes it? Incorrect arc length can be caused by improper electrode positioning, incorrect settings on the welding machine, or operator error.
  2. How can you prevent it? Ensure proper electrode positioning, adjust machine settings according to the material and thickness, and provide adequate training for operators.

Incorrect Travel Speed

  1. What causes it? Incorrect travel speed can be caused by operator inexperience, improper machine settings, or inconsistent movement during welding.
  2. How can you prevent it? Train operators to maintain a consistent speed, adjust machine settings appropriately, and practice to improve technique.

Cracks

  1. What causes it? Cracks can be caused by rapid cooling, high residual stress, or improper welding technique.
  2. How can you prevent it? Control cooling rates, use preheating and post-weld heat treatment, and ensure proper welding techniques are used.
