| Abstract: | A possibility of correcting N. N. Rykalin's known equation to calculate spot peak temperature in the welding area is shown. It is suggested to take into account factors related to metal fusion: latent heat of fusion and overheating degree. A possible experimental estimate of thermal efficiency value application in calculations for a point source at machine welding where the heat source distributed is carried out. |
