Upgrade your welding with the V30 smart annealing control system

Annealing is a critical part of the joining process in many applications, especially when working with steel. This crucial heat treatment modifies the material properties, ensuring optimal performance in the subsequent production steps. This article explores the different annealing options, focusing on the advanced ‘V30 smart’ control system.

Why is annealing required?

During electrical resistance butt welding, hardenable steels experience structural changes in the heat-affected zone. To ensure the required material properties, a controlled annealing process, particularly soft annealing, is crucial. This process reduces existing precipitates of cementite or pearlite, typically at temperatures between 650°C and 750°C.

Different annealing alternatives

Traditionally, annealing could be manually controlled by the operator - that simply presses a button until the desired annealing color is reached - or timed with a relay. However, these methods lack precision and control. A more advanced option is the "V30 smart" control unit, offering sophisticated program-controlled annealing.

Introducing the ‘V30 smart’ welding and annealing control system

Developed by STRECKER, a renowned manufacturer of welding machines for 90+ years, the ‘V30 smart’ control system empowers users to tailor both the welding and subsequent annealing processes to their needs.

Advantages of ‘V30 smart’

• Intuitive user interface: Featuring a rotary push-button and a large 7-inch display, the system enables easy program selection and parameter adjustment.
• Seamless program management: IntUSB and Ethernet connections facilitate program exchange between units, archiving, editing, and management. Pre-existing welding programs from older controllers can also be imported.
• Precise time-controlled annealing: Up to three segments ensure optimal post-processing even for critical materials.
• Optional pyrometer integration: Optimize thermal post-treatment of high-carbon steel or special alloys with up to five control segments and graphical temperature visualization.
• Robustness and security: The V30 smart can handle voltage fluctuations of +/- 8% and boasts password protection for sensitive areas.
• Customizable program naming: Utilize company-specific designations for efficient program identification.
• Easy upgrade path: Transition from previous V12/V20 models to the V30 smart is seamless.
