A method for sterile connection of tubing includes welding the tubing sections together using an efficient laser. The ends of the tubing sections are brought together prior to the initiation of welding, facilitating isolation of interior passage of the tubing sections. The method can be carried out by an apparatus which is relatively inexpensive and compact.
