The invention relates to a profile in a container, where a profile (5, 6, 7, 8, 101) comprising a cross section where at least a part of the cross section over a length of the profile is provided with a crumple zone, which crumple zone has a critical buckling load being smaller than the critical buckling load for zones abutting the crumple zone. The invention further relates to a method of manufacturing a profile for a container, where one or more profiles (5, 6, 7, 8, 101) in the container (1) is provided with a crumple zone, which crumple zone has a critical buckling load being smaller than the rest of the profile (5, 6, 7, 8, 101). The invention also relates to abase structure for a container, comprising a pair of bottom side rails, a front sill (4) in one end and a door end in an opposite end, a number of crossmembers (8) placed in parallel with the front sill (4) and door end and extending from a bottom side rail (2) in one side of the container (1) to a bottom side rail (2) at the other side of the container (1), wherein the crossmember (8) comprises a cross-section, where at least a part of the cross section over a length of the profile (5, 6, 7, 8, 101) is provided with a crumple zone, which crumple zone has a critical buckling load being smaller than the critical buckling load for zones abutting the crumple zone.

One aspect is an apparatus including a node having a socket configured to receive a component and a detachable additively manufactured nozzle co-printed with the node and arranged for adhesive injection between the component and the socket. Another aspect is an additively manufactured apparatus including a first additively manufactured component having an area configured to receive a second additively manufactured component. The first component includes an adhesive channel for injecting adhesive into the area when the second component is being connected to the first component. Another aspect is an apparatus including a plurality of additively manufactured components each having an adhesive injection channel. The components are connected together such that adhesive injection channels are aligned to form an adhesive path that allows adhesive flow between the components.

A spot welding system comprises a robot which changes a relative position of a spot welding gun and a workpiece. A control device drives an electrode drive motor so that a movable electrode of the spot welding gun abuts on the workpiece, and is formed so as to perform a position detection control which detects a position of the workpiece based on a position of the movable electrode when a state value of the electrode drive motor deviates from a predetermined range. An operation program includes a workpiece detection parameter for performing the position detection control. The workpiece detection parameter is set at each of welding points in the operation program.
