A method for producing a frame component for a door frame structure of an aircraft. A connecting zone is generated on a first and a second assembly surface of a connecting component in each case by generating a surface texture on the assembly surfaces, wherein the connecting component is formed from a metal material. The assembly surfaces of the connecting component are placed against a door frame member and against an attachment member, wherein the door frame member and the attachment member are each formed from a fiber-reinforced thermoplastics material. Furthermore, the connecting component and the door frame member are welded, and the connecting component and the attachment member are welded. A frame component and a door frame structure are also described.

A moveable seam welding machine, system, and method of use is provided. The seam welding machine includes at least one sensor that generates at least one data point having geolocation coordinates incorporated or integrally formed therewith. The data point typically relates to the integrity or quality of the welded seam created by the machine. The sensor generates data points which may be evaluated in alarm logic for abnormalities or anomalies. The geolocation coordinates inherent or integral to the data point may be plotted or registered overtop satellite imagery. The coordinates of the anomalies or the registered image, or both, can be provided to the workman or operator so he/she may manually inspect the geolocation at where the abnormal or anomaly data point was generated by the sensor to spot check the welded seam by hand.

Described is a heated gaseous welder system and associated methods of welding plastic with the heated gaseous welder system. The heated gaseous welder system includes a welding tool and a welder control unit. The welder control unit includes a gaseous control system and a heater control system. The gaseous control system is configured to selectively supply a gas to the welding tool and control at least one characteristic of the gas supplied to the welding tool. The heater control system is configured to selectively control power supplied to the welding tool.

A thermal welding marking system for attachment to a thermal welding machine including: a hammer arm rotatably connected to a mounting bracket attached to the thermal welding machine, wherein a distal end of the hammer arm is shaped to receive a marker or pen therein; a cable or spring connected to the distal end of the hammer arm; a cable connecting the hammer arm to a hand lever mounted adjacent to hand controls on the thermal welding machine, wherein movement of the hand lever raises or lowers the distal end of the hammer arm and thereby raises or lowers the marker or pen therein. In operation, the thermal welding machine is advanced across the edges of overlapping building roofing material and the marker or pen is intermittently lowered/raised to mark locations along a seam of the edges of overlapping building roofing material where the seam is either open or closed.

A contact welding heating component and to an automatic welding machine for plasticizing the edges of thermally fusible/meltable material sheets disposed so as to overlap at least partially. A roughening device for the material sheets, which is disposed upstream of the trailing-material edge of the heating component in the direction of movement of the contact welding heating component, protrudes beyond the upper side of the heating component and/or the lower side of the heating component, wherein the roughening device extends transversely to the direction of movement of the contact welding heating component, adjoining the trailing-material edge of the heating component, and includes a number of sharp-edged raised roughening elements extending in the direction of movement of the contact welding heating component, preferably having a variable height in the direction of movement of the contact welding heating component. The automatic welding machine includes a contact welding heat component thus designed.

A machine for welding an overlapped region of two adjacent strips of material and a method of using the same. The machine includes a housing with front and rear ends, a wheel train engaged with the housing for moving the housing across the material; a nozzle on the housing having a welding head at a free end; the nozzle being positionable at least partially beneath the housing's bottom wall for welding the overlapped region; front and rear pressure rollers engaged with the housing, where the front roller is positioned forwardly of the welding head and the rear roller is positioned rearwardly of the welding head; wherein the rear pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a forward direction; and the front pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a reverse direction.
