Butt-welding process using an automatically controlled electro-welding machine

摘要

It concerns butt-welding of parts made of plastics material(s). For this purpose, the invention proposes correcting, according to an ambient temperature which is measured in the environment of the parts at the moment of welding, at least one of the following parameters: pressure(s) for contact and/or welding of the parts, electrical energy to be supplied to means for displacement of the said parts, stroke(s) of relative displacement of the parts, time for obtaining beads at the end of the parts during the phase of heating the latter.
