At what angle should filler metal be added to the molten puddle?

• A. 30 degrees
• B. 45 degrees
• C. 15 degrees
• D. 60 degrees

Answer: (C)

The most suitable angle for adding filler metal to the molten puddle is at approximately 15 degrees. This angle allows for efficient control of the filler metal without disrupting the molten puddle significantly. By applying filler metal at this angle, the welder can ensure that the filler blends seamlessly into the base metal, promoting a strong and cohesive weld. Using a shallow angle like 15 degrees helps to minimize the risk of overheating the filler material and allows for better penetration into the joint, leading to a more stable weld joint. This technique is particularly important in maintaining the integrity of the weld and ensuring that the filler metal flows properly into the desired areas, which contributes to an overall strong and aesthetically pleasing weld. Greater angles may create challenges by either causing the filler metal to deposit too far from the base metal or potentially interfering with the stability of the molten puddle, which could adversely affect the quality of the weld. Thus, 15 degrees is optimal for controlling the feed of filler metal while ensuring the molten puddle remains well-formed and effective.
