The Effect of Tandem Cooling on Welding Thermal Stress

Tandem Cooling이 용접열응력(熔接熱應力)에 미치는 영향(影響)

In this paper, two dimensional theoretical solutions of temperature distribution and thermal stress due to tandem cooling in an infinite plate were studied. Temperature distribution and thermal stress were calculated by numerical integration. Calculated temperature distributions were in good agreement with the result of the experiments by Park, and calculated thermal stresses were in good agreement with physical phenomena. This solutions could be applied to the practical tandem cooling operations.
