A method for forming butt joints between thermoplastic members by resistive implant welding. A tongue is formed on one member to be joined and a complementary groove is formed in the other member. A resistive implant is placed between the tongue and the groove which are then pressed together by an applied pressure. An electric current is run through the resistive implant to melt a portion of the thermoplastic material of both the tongue and groove, and the melted plastic intermingles through the implant. When the electric current is removed, the plastic cools, forming a weld.
