Method for Forming-Induced Weld Seam Treatment

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method for treating weld seams using deformation that is induced by the welding process itself. Specifically, after welding parts together (with or without filler materials), the weld seam and the areas directly adjacent to it are mechanically deformed while the weld is still cooling and hot from the welding heat, which improves the characteristics of the weld and the material around it.

Use CasesContent extracted from patent full text and abstract with AI.

• Manufacturing of vehicles (such as automotive or rail) where strong and durable metal joints are required.
• Construction of pipelines and pressure vessels that need high-integrity welds.
• Production of steel structures such as bridges, cranes, and building frameworks.
• Shipbuilding and aerospace industry where welded joints must withstand high stresses.
• Repair and maintenance of metal structures or equipment with welded connections.

BenefitsContent extracted from patent full text and abstract with AI.

• Improves the mechanical properties and durability of the welded joint.
• Reduces the likelihood of defects like cracks or weaknesses in and near the weld seam.
• Makes the welding process more efficient by exploiting the residual heat for deformation treatment, potentially reducing additional processing steps.
• Leads to stronger and more reliable connections in metal components.
• May extend the lifespan of welded structures by enhancing fatigue resistance.

Patent Abstract

Die Erfindung betrifft ein Verfahren zur umforminduzierten Schweißnahtbehandlung, insbesondere beim Schweißen mit Zusatzwerkstoff zum Fügen von Bauteilen, wobei nach dem Schweißvorgang eine umformende Bearbeitung der Schweißnaht unter Ausnutzung des beim Schweißen eingebrachten Wärmeeintrages erfolgt und erfindungsgemäß während des Abkühlens der Schweißnaht sowohl die Schweißnaht als auch das an die Schweißnaht beidseitig angrenzende Grundmaterial (indirekt) einer Umformung unterzogen wird.
