PROBE2 Posted July 10 Share Posted July 10 Hi, looking to get a nice ported K Series aluminium cylinder head welded on one combustion chamber following valve/piston contact, any recommendations on someone who could do it? It’s just the welding required. Regards Paul Link to comment Share on other sites More sharing options...
Ed White Posted July 10 Share Posted July 10 Where are you Paul? Possibly, but no guarantees as a lot of variables in the material , regards, Ed Link to comment Share on other sites More sharing options...
PROBE2 Posted July 10 Author Share Posted July 10 Ed, in Bedfordshire, I thought worth a go as a decent spec head so worth saving. Link to comment Share on other sites More sharing options...
Mike Biddle Posted Monday at 21:45 Share Posted Monday at 21:45 Hi Ed, I had some laser welding done on a 1937 aluminium sump last year, excellent work, and a brilliant method, but providers are few and far between and often busy. I used a guy in Boscastle down in Cornwall, he does a lot of work for F1 teams, but enjoys the occasional diversion to something different. You could always send it by courier. If its of interest PM me and I'll send his details. Link to comment Share on other sites More sharing options...
Miker7 Posted Tuesday at 06:51 Share Posted Tuesday at 06:51 Does welding affect the heat treatment of the head at all? I'm aware we are all concerned about them over heating and warping, welding will be a much higher temperature (but more localised). Link to comment Share on other sites More sharing options...

Thermal shock is more the issue. If we weld anything serious we can pre heat it so the whole job is warm / hot to reduce thermal shock. Cylinder heads are designed to cope with quite serious explosions happening below them so are generally quite strong. Link to comment Share on other sites More sharing options...
OldAndrewE Posted Tuesday at 14:43 Share Posted Tuesday at 14:43 Watch some of Allen Millyard's YouTube stuff, for example this one Kawasaki Z1 Super Six Cylinder head - How its Made (youtube.com) He cuts up aluminium bike engines to make bigger engines. He preheats them in a gas barbeque before Tig welding Link to comment Share on other sites More sharing options...
