MATHEMATICAL MODELLING MEAN RESISTANCES TENSILE STEEL WELDED JOINTS BY RESISTANCE LOW ALLOY TENSILE BASIC MATERIALS
In the paper are elaborated the mathematical models of two types of low alloy steels used for the construction of fluids for the transport of fluids. The experimental study was conducted on two types of low alloyed steels: steel 13CrMo4-5 and 16Mo3. The correlation between the average tensile breaking strengths of the welded joints (untreated or heat treated by stress) by means of the processes 111, 141 and 511, as well as the breaking strength of the base materials (13CrMo4-5 and 16Mo3) according to the linear energy used for welding.
Keywords: low alloy steels, model, the average tensile breaking strengths
