Systems and methods for adhesive injection for node assembly

A method of forming a bond between a joint and a corresponding tube connected to the joint, the method comprising:

• fitting an inner protrusion of the joint into the corresponding tube, wherein the inner protrusion includes one or more fluid delivery paths built into a side wall of the inner protrusion that provide a channel from one or more fluid delivery ports provided on the joint to a space between an inner surface of the corresponding tube and an outer surface of the inner protrusion;
• heating at least a portion of the joint to a surface temperature of at least about 50° C.;
• attaching (1) an adhesive source to at least one of the fluid delivery ports and (2) an negative pressure source to at least one of the fluid delivery ports;
• and
• injecting adhesive into the space between the inner surface of the corresponding tube and the outer surface of the inner protrusion by (1) providing adhesive from the adhesive source through the at least one fluid delivery ports and (2) pulling adhesive into the space by the negative pressure source on the at least one of the fluid delivery port.
