Abstract
Algorithm of numerical estimation of temperature fields in a welded joint (penetration zone) in butt welding of elements with a foam macrostructure is suggested. This algorithm is based on corresponding modelling of the foam macrostructure using statistical data on pore parameters. It is shown that welding conditions at a high porosity should substantially differ from those for a solid material.
Keywords: mathematical modelling, foam (porous) macrostructure, stochastic characteristics of macrostructure, welding processes, super-light structural materials, permanent joints, molten pool, fusion welding, material porosity, temperature fields
