Abstract
A method and machine for producing welded reinforcing steel rod mats for use in the production of DIN-conforming reinforced concrete components having primarily no static loads, and to such a reinforcing steel rod mat, uses a welding device, one or more reinforcing steel rods, and one or more stay braces in the case of uniaxial reinforcing steel mats, positioned relative to each other with position control and optionally with position correction of the reinforcing steel rods to be welded together, and a reinforcing steel rod is welded in the area of at least one of the ribs thereof to a stay brace, or to another reinforcing steel rod in the area of at least one of the ribs of the rod.
Claims5
A method for producing welded connections between steel bodies being subject to alternating loads under operational conditions, the method comprising the steps of:
- a) positioning at least one welding device and at least two different elements of the group formed by:
- obliquely ribbed reinforcing steel rods and stay braces, relative to one another;
- b) welding the obliquely ribbed reinforcing steel rod exclusively in the area of at least one of its oblique ribs to another element;
- and
- c) repeating steps a) to b) until the desired number of welded connections has been produced,
- wherein providing a position control and a correction of the position of the obliquely ribbed reinforcing steel rod to be welded is carried out in or after step a), wherein the position control utilizes mechanical or optical sensors, wherein the position correction comprises rotating the element(s) about its longitudinal axis by at least 360°, and wherein step b) is carried out in the range of more than 30% of the maximum height of the respective rib.
