Abstract: In order to provide a method for heating an object (102) that is simple to perform and makes it possible to heat an object (102) efficiently and reliably, it is proposed that the method should include the following: providing an object (102) to be heated; applying at least one energy beam (108, 109) to the object (102) to be heated, wherein at least one energy beam (108) is guided over the object (102) to be heated multiple times, along a predetermined intended heating path (114), and this heats the object (102) along the intended heating path (114); determining a temperature distribution over the intended heating path (114), for identifying one or more deviation points (120) at which an actual local temperature differs from an expected and/or calculated temperature; changing and/or supplementing the application of at least one energy beam (108, 109) in order to compensate for the temperature difference at one or more deviation points (120).

Abstract: The invention relates to a method for determining whether two plastics components (1, 2) to be welded to each other in a joint plane are welded to each other after a welding process has been carried out, characterized in that the position of a reference plane is determined from a reference point before the welding process is carried out, then the welding process is carried out, and the position of the joint plane or the thickness of the components (1, 2) welded to each other is determined from the reference point during or after the welding process.

Abstract: For continuous welding of plastic components (1, 2) of a product along a join region extending over the circumference, the plastic components (1, 2) to be welded are first positioned in the join position thereof and fixed therein. Then, for the welding process, the product is transported past a fixed heat source (5) and is subjected to its own rotary movement in the region of the fixed heat source (5), in addition to the transport movement, in order to insert the welding energy into the join region.

Abstract: The invention relates to the melting of a thermoplastic, in particular for welding plastic parts (1). The plastic is heated by supplying an exhaust gas. According to the invention, a further gas is mixed with the exhaust gas prior to the supplying process.

Abstract: The invention relates to an industrial welding system with a tool table, which has at least one tool holder for fixing workpieces that are to be welded. According to the invention, the tool holder is placed on a rotating frame that is mounted in a manner that enables it to rotate about a rotation axis that is parallel to a table base area of the tool table. The invention serves to weld plastic parts for the automotive industry.
