Which welding processes generate less heat affected zone?

Which welding processes generate less heat affected zone?

With regard to welding procedures, those processes with low heat input will cool faster, leading to a smaller HAZ, whereas high heat input will have a slower rate of cooling, leading to a larger HAZ in the same material. In addition, the size of the HAZ also grows as the speed of the welding process decreases.

What are the causes of welding defects?

Causes:

• Too high weld current.
• Too fast weld speed.
• The use of an incorrect angle, which will direct more heat to free edges.
• The electrode is too large.
• Incorrect usage of gas shielding.
• Incorrect filler metal.
• Poor weld technique.

What are the factors that must be considered when choosing a welding process?

To evaluate the welding process most appropriate for the job at hand, the following factors would typically be considered:

• Type of material being welded (see table below)
• Thickness of the material.
• The welding position.
• Type of welding power source and the amount of current available.
• Time requirements.
• Working conditions.
