Abstract

The influence of the thermal welding cycle of the gray cast iron was established, as well as the behavior of the isotherms during the heating and cooling of the material. For the study, a bevel joint was considered in simple V at 60o, in a thickness of 12 millimeters. The parameters analyzed were the current intensity, the arc voltage, the welding speed, as well as the linear energy of the process and the incoming energy. To establish the isotherms, temperatures of 900, 800, 600 and 200 oC, were taken at different distances from the welding arc. It was determined that during the thermal cycle, the distribution of temperature along the seam in the branch of heating and cooling, in the first, the curves is more abrupt, that is, have higher slope than in the branches of cooling.
