PRINCIPLES OF HIGH FREQUENCY INDUCTION TUBE WELDING

adds a fifth roll at the bottom of the tube, allowing smaller diameter side rolls to be used. Many smaller mills use three rolls mounted 120 degrees apart. Some are orientated with a grooved roll at the top of the tube (D), others with a roll directly below the tube. D eliminates edge misalign-ment and is especially suited to D/T ratios above 10:1.

Increasing tube mill welding speed: Examining technology

Oct 25, 2001 The key to increasing tube mill weld speed is to provide consistent roll forming of the strip material for edge presentation at a weld station. This allows the TIG beam welding process to maximize the mill output. Weld speed depends on: 1. Strip material composition and weldability and certification tolerance limits. 2.

Optimizing Efficiency in HF Tube Welding Processes

types of high frequency tube welding equipment. Modern solid state welders can convert 60Hz power to the high frequencies used for welding at efficiencies of 90%, compared to a maximum 65% for the older vacuum tube equipment. At the very best, improvements in welder design may raise this figure by another 5% or so. In contrast, the process
