    摘要： The present invention relates a method for the welding of pipes (1) of a weldable polymer material, where the pipe has ends (1a, 1 b), and a muff (7) of a weldable polymer material, where the method comprises that the muff (7) is placed with an overlap over the ends (1a, 1b) of the pipes, that the muff (7) is welded to the ends (1a, 1 b) of the pipes through the placing of an electrically conducting band (L, 9) that is permeable to molten plastic between the pipe (1) and the muff (7), and that a power supply (PU-DC, PU-AC) is connected to the band (L, 9) through feed cables (M) and that an electrical current is supplied in order to heat the band (L, 9) and the surrounding polymer material such that they melt together around the band (L, 9) in order to form a weld, where the method comprises that the initial ambient temperature T 0 of the weld is measured before the band is heated, that a voltage U L across the band is measured, that the electrical current l L supplied to the band is measured, that the initial resistance R0 of the band is calculated before the band is heated, that the electrical current supplied to the band is caused to increase, that the resistance R of the band is calculated based on the voltage and the measured current, that the change ΔR in resistance is calculated, that the increase ΔT in temperature of the band is calculated based on the change in resistance and in that the temperature T w of the weld is calculated through adding the initial ambient temperature T 0 of the weld and the increase ΔT in temperature of the band. The invention relates also to an device for the welding of a pipe (1) of a weldable polymer material.
