Abstract

The results of computer simulation (using the ELCUT software) of the magnetic field of a weld of ferromagnetic pipes both in the weld body and from outside the weld are given. Both linear and nonlinear cases of magnetization are considered. It is shown that in the nonlinear case the magnetic permeability and induction in the weld body are extremely nonuniformly distributed over its thickness, i.e., different weld layers operate on significant different sections of the magnetization curve.
