Method for joining tubular members |
摘要 |
A method is disclosed for inserting an end of a first tubular member into a complementary end of a second tubular member and attaching (e.g., welding) the adjacent surfaces of the inserted ends in a tight peripheral bond. In the method, a substantially continuous protrusion is formed in either the first or second member. Thereafter, the first and second tubular members are placed relative to each other such that a current may be passed through the protrusion and a seal may be formed, thereby joining the members.
