Fresh thread , same topic .......reguarding the Linear Impact Hammer ......having discovered that the linear induction motor wasn't a good application to this project but that the pernanent magnet inducion motor certainly is ...a few new ???s have surfaced.....
To simply forge (reshape / displace) the metal I am thinking that the blows could be more of the lighter peen , higher impact / speed variety ...getting the most bank for your buck so to speak ....preserving the "heat" in the work peice (less actual real-time) that the peen ; part ; and anvil-face are in solid contact with each other......
for the forge weld how ever ...I picture a heavy-er peen , a smoother lower speed blow to allow for the joining of the two halves , and the expulsion of the flux ...and to maximise the working life of each "heat" the return stroke would be as fast as practically possible just short of the point of causing a rebounding of the whole frame of at least the upper driving portion......does this sound like the characteristics of a good power-hammer cycle
the thinking is that the downward and upward strokes can easilly be tailored as to the ballance of speed and force ......with the L.M. technologies available today
Please feel free to take these threads to any more realavent forums ......I do not have time to monitor anymore forums ....and frankly anvilfire and practical machinist seem slugish for me to post in....I have had 20 minutes of typing simply vanish more than once
if someone can get ahead of me on this ....great all I ask is that progress and improvement be relayed back to me , and others interested in this concept !!!
Please keep imput based on EXPERIENCE-forging and forge welding ....
and note assumptions and conjectures as such , to keep the foundational research on this at a pure-ist level , Thankyou in advance for your help

REVEIW of concept :
prototype trip-hammer (forging power-hammer)
need to drive peen directly or indirectly with L.M. or L.I.M.>>>
hydrolic coupling >>master-cylinder / slave-cylinder , with air cushion most likely design>>
single phase and DC prefered but concept will be advanced even if 3 phase only>>>
air powered hammers are the inspiration, but terribly inefficient ...and
control of speed & force and return make L.M.s a very big hopefull
