Mould, Instrument, Die Mend on Stainless Metal, Aluminum, and Brass Molds

A sharpened 1mm tungsten electrode is used for the steel mould maintenance.  We used an alligator design and style grounding clip on the bottom of the mould.  .015″ 316 stainless steel fill wire is used for this application.  Assortment of fill wire diameter can transform the electricity settings desired and the ease of filling the parts.

The Orion Pulse 250s is set to 20ws electricity with sloped agitation (a large frequency electricity overlay that increases penetration and spot sizing) enabled and 15ms duration.  The placement of the fill wire in relation to the electrode has an effect on how the metallic flows and attaches.  Correct orientation can be extremely essential in attaining effective welds.  Numerous layers can be placed together the surface that wants to be fixed.

For the aluminum samples we used a 1mm electrode with a marginally blunted tip to enable avoid digging holes.  We used 4043 fill wire and set the Orion 250s to 27ws electricity at 15ms duration.  The get the job done-piece is most likely anodized and it brought about some problems with grounding (burn marks wherever the alligator clip connected).

Brass is a difficult metallic to weld because of to the large zinc information.  The zinc has a lower boiling temperature and it burns out of the brass leading to soot and choppy weld puddles.  We were being able to use silver fill wire and copper fill wire to fill in the hole.  We attempted to use brass fill wire with weak success.  The Orion 250s is set to 70ws electricity to attach the silver fill wire and 130ws electricity to attach the copper fill wire.  The tip of the electrode is blunted for this application.

The Orion Pulse 250s is an great alternative for repairing molds and dies.  The contact monitor user interface can make it easy for operators to swiftly good tune electricity settings and come across effective weld parameters.  An articulating arm can be coupled with the Orion Pulse 150s to let for increased workspace clearance and versatile positioning. Please notice that the stylus can be taken out from the microscope and used in a handheld method if wanted (much easier to obtain some geometries).
