RMU Welding

Because RMU enclosures must be gas-tight, weld quality directly determines whether the product works. Heat input on stainless steel is sensitive: too much causes distortion and discolouration, too little leaves insufficient penetration.

The system is set up to run inside the narrow parameter window required for thin stainless sections. Where seam tracking is used, deviations from the actual joint line are compensated so the continuous seam needed for tightness is maintained.
