745 Welding, Cutting, and Brazing Safety

Weldability

Weldability is the ability of a material to be welded under specific conditions without causing defects, cracks, or significant loss of strength.

Factors affecting weldability include material composition, welding process, and environmental conditions. Weldability also refers to how easily procedures can produce welds with properties equal to or better than those of the base material.

Many factors influence the weldability of metal, including:

• The chemical composition of the metals involved
• The effect of radical temperature changes on the various elements
• The expansion and contraction characteristics of the base metals
• The filler metal (welding rod or electrode)
• The joint design
• The welding procedure
