    摘要: A pipe welding structure includes: a channel plate that includes a fluid channel; through-hole plates stacked on the channel plate, each of the through-hole plates having through holes that communicate with each other and forming a combined through hole; and a pipe inserted into the combined through hole and welded to one of the through-hole plates disposed farthest from the channel plate, the pipe internally including a pipe channel that connects to the fluid channel.

    摘要: A truss structure of a spray boom assembly includes a top member, a bottom member, and a first truss member positioned between the top member and the bottom. The truss structure also includes a first connecting member welded to the top member and the first truss member, and a second connecting plate welded to the bottom member and the first truss member.

    摘要: A tube arrangement as described herein can include a first and a second wedge shaped circular tube, or pie cut, that are each defined by a front face and a back face, a minimum face-to-face distance between the front face and the back face that is smaller than a maximum face-to-face distance between the front face and the back face. A plurality of evenly spaced keys is dispersed along the front face of the first pie cut. The keys are engaged with a plurality of evenly spaced facets dispersed along the back face of the second pie cut. A weld seals a joint located between the front face of the first pie cut to the back face of the second pie cut. This arrangement is beneficial for constructing custom shaped exhaust tubes by welding the offset pie cuts as needed.

    摘要: An internal line-up clamp for welding pipe lengths end-to-end includes a clamp ring made up of a plurality of clamp ring elements that are angularly distributed around the circumference of the clamp ring. The clamp ring elements are divided into mutually opposed groups that are interdigitated such that the clamp ring elements alternate from one group to the other around the circumference of the clamp ring. A longitudinally-acting actuator system drives relative longitudinal movement of the groups to effect clamping expansion of the clamp ring by wedging interaction between the circumferentially-alternating clamp ring elements of the groups. By expanding the clamp ring in alignment with a weld plane between the abutting ends, the same clamp ring may be used to align the pipe lengths and to back a weld between them.
